Taptite thread forming screws
Mechanical properties according to ISO 7085:1999.
When tapping the neccessary force required is always less than the tensile strength of the screw.
The size of the mounting hole, precision, material properties and lubrication method affects the tapping torque.
The pull-through strength value in the following chart is an directional value, not a constant value set by the ISO standard.
Case hardened self-tapping screws has to be marked with a “-0-” marking.
The mark is mandatory in socket and hex head screws with nominal diameter M5 or larger.
If separately requested, this mark can also be put in smaller or different types of screws.

Fasteners for sheet metal
Press-in fasteners can be used to create, either internal or
external threaded joints on sheet metal. These joining elements are securely clinched to the host material.
The joints can be used to attach and detach objects several
times with a screw or a nut. This feature allows the improvement of manufacturing efficiency and the production of complex sheet metal solutions, such as closed corner products.
There are two types of press-in fasteners, SELF-BROACHING
and SELF-CLINCHING based fasteners. Both types are installed to a drilled or punched mount hole in the host material, by applying a constant squeezing force.
82
more than you expect
Self-broaching fasteners
A fastener is attached to a mount hole and is pressed from the opposite side, so that the bottom face of the fastener
clinches to the host material. The serrated clinching ring in the shank of the fastener provides torque resistance, which
prevents any turning between the host material and the fastener. This type of fastener suits well for thin and hard
materials.
Self-clinching fasteners
Fasteners with a hexagon head or serrated clinching ring are attached to the host material in a mount hole. The bottom face of the fastener is designed to displace the host material causing it to flow into the thread or groove of the
fastener, thus locking the fastener securely to the host material. This type of fastener suits especially for sheet metals of
medium hardness with minimum thickness of 0.8 mm, as well as for softer materials.
More specified information about the properties and benefits of an individual fastener can be found
from the product page.

WEBSO WEMINLOK
more than you expect
WEARB and WEARBSO
WEARB and WEARBSO are internal threaded self-broaching nuts with a serrated shank. When installed the
shank rivets around the hole, while the serrated part clinches itself firmly to the host material, ensuring a strong
and enduring joint.
WEMINARB
WEAMINARB is a miniaturized WEARB. It is especially designed for spots with limited space to operate.
WEMINLOK
WEMINKLOK includes the properties of WEMINARB. The last few leads of the nut are distorted in order to give
the nut the ability to lock attached fastener, making it resistive to working and vibration loosening.
WES and WECLS
WES and WECLS are self-clinching flush nuts, which are installed into a mount hole and locks in place by
shaping the host material causing the displaced material to flow to the serrated ring at the bottom face of the
fastener.
WEFH and WEFHS
WEFH and WEFHS are self-clinching studs that are installed into a mount hole and lock in place by shaping the
host material causing the displaced material to flow smoothly and evenly into the groove and around the ribs.
WEHFH
WEHFH is a self-clinching stud, which is installed into a mount hole and lock in place by shaping the host material causing the displaced material to flow smoothly and evenly into the groove and around the ribs.
WEF
WEF is a self-clinching flush nut, which allows level surface on both sides of the host material. When installed
the hexagonal head embeds into the base material causing the displaced material to flow into the groove, thus
locking the fastener to the host material.
WEBSO and WESO
WEBSO and WESO are self-clinching standoffs, which allows fastening in different distances from the host material. When installed, the hexagonal head embeds into the host material causing the displaced material to flow
into the clinching groove.
85
Self-broaching nut
WEARB and WEARBSO are internal threaded self-broaching nuts
with serrated shank.
When installed, the bottom face of the nut mounts around the
hole, while the serrated shank clinches firmly to the host material, ensuring a strong and enduring joint.
Benefits
• Suits well for thin and strong materials
• Suits well for aluminium, light metals, magnesium etc.
• Can be installed using manual or automatic tools
• Suits well for both drilled and punched mount holes
• Suits well for materials with thickness 6 mm or less
• Suits well for the attachment of two sheets
Installation
and design instructions
Mount hole diameter in sheet metal
Nut types
The mount hole can be made by drilling or punching.
Hole tolerance should be --0.00 + 0.1 mm.
If there are room for the serrated ribs in the mount hole, using a size
bigger nut is recommended.
Installation
Usage
To achieve the best installation result, it is important to use a properly
manufactured riveting tool (see page 92). It is recommended to use
a clamp to achieve a constant result. Small amounts can also be
installed by hand tools
In order to achieve the best possible joint, it is recommended to install
the screw through the opposite side of the head, although it is possible
to install the screw from the top face side.

Miniature self-broaching nut
WEMINARB and WEMINOFF are miniaturized internal threaded
self-broaching nuts with serrated shank.
When installed, the bottom face of the nut mounts around the
hole, while the serrated shank clinches firmly to the host material, ensuring a strong and enduring joint. This product is especially designed for places with limited space to operate.
Benefits
• Suits well for thin and strong materials
• Suits well for light metals such as aluminium, magnesium, etc.
• Can be installed using manual or automatic tools
• Suits well for both drilled and punched mount holes
• Suitable for materials with thickness between 0.5 - 3.0 mm
• Can be installed to a place with limited space or near the edge
of the sheet.
Installation
and design instructions
Mount hole diameter in sheet metal
Nut types
The mount hole can be made either by drilling or punching.
Hole tolerance should be --0.00 + 0.1 mm.
If there are room for the serrated ribs in the mount hole, using a size
bigger nut is recommended.
Installation
Usage
To achieve the best installation result, it is important to use a proper
riveting tool (see page 92). It is recommended to use a clamp to
achieve a constant result. Small amounts can also be installed by
hand tools.
In order to achieve the best possible joining element, it is recommended to install the screw through the opposite side of the head, although
it is possible to attach the screw from the top face side.

Self-clinching stud
Self-clinching studs WEFH and WEFHS are external threaded
joining elements, which are installed in to the sheet metal by
pressing.
The ribs and the groove at the bottom face of the stud shape
the host material creating a strong and enduring joining.
Benefits
• Easy to install by pressing
• High torque resistance
• Clean joining
• Level opposite side of the joining
Installation
and design instructions
When installed, apply squeezing force sufficiently enough to
achieve a steady embedment of the head. Using excess force
must be avoided. Installation squeezing force varies depending on the material of the sheet and the size of the fastener.
See page 104 for more information.
Noteworthy
In particular installation combinations depending on the size
of the fastener and the thickness of the sheet metal, the anvil
must be equipped with a countersink. Countersink is needed
for self-clinching studs M5 or less when installed in to a sheet
with thickness 1.5 mm or less. Self-clinching nuts M6 or larger
also require a countersink, when the sheet thickness is 2.5
mm or less.
Sheet metal material
The sheet metal material hardness must be less than 80 Rb (150 VPN).
Stainless steel sheet hardness must be less than 70 Rb (128 VPN).
Mount hole
Holes can be made by punching or drilling with -0.00 / +0.08 mm
tolerance.

Self-clinching flush nut
WEF self-clinching flush nut is designed to create level sheet surface on both sides of the joint.
When the nut is clamped it embeds itself in to the sheet by displacing the host material causing the material to flow into the
groove, thus forming a strong and enduring joint.
Benefits
• Allows the creation of a joint in places with limited space
• Easy to install
• High torque resistance
• High push-out force resistance
• Level surface on both sides of the joint.
Installation and design instructions
Mount hole
Sheet metal thickness
The mount hole tolerance has to be -0.00... + 0.08 mm
See the chart on the next page.
Sheet metal hardness
Shank
Stainless steel sheet hardness needs to be less than 70 Rb (128 VPN).
It is recommended to use longest possible shank length that
the sheet metal thickness allows. This creates the strongest
possible joint.
Installation
Installation has to be always done by applying constant squeezing force,
never by stamping.
100
Installation side
Installation to the joint is always recommended to be done
from the opposite side of the head (round face in this case).

Self-clinching standoff
WESO and WEBSO self-clinching standoffs are designed to act
as standoffs or spacers in the sheet metal.
When the standoff is clamped it embeds itself in to the sheet
by displacing the host material causing the material to flow
into the groove, thus forming a strong and enduring joint.
Benefits
• Creates a stationary joining element
• Available as blind or thru-holed
• Level surface on the opposite side of the joint
• Clean installation
• Broad range of sizes
Installation

All self-clinching fasteners
are easy to install without
special tools. Self-clinching
fastener is installed by applying constant squeezing
force. It is recommended
to install the fastener into a
punched or drilled mount
hole.
WES & WECLS self-clinching nut installation
1. Drill or punch a proper sized hole
into a sheet metal and install the press-in
fastener directly into the place.
2. Clamp the fastener steadily with a right
sized tool above the fastener until the head is
embedded into the sheet.
3. Fasten the desired fastener from
the opposite side.
WEF Self-clinching flush nut installation
1. Drill or punch a proper sized hole
into a sheet metal and install the press-in
fastener directly into the place.
2. Clamp the fastener steadily above the
nut until the hexagon head of the nut embeds
into the sheet metal.
WESO & WEBSO self-clinching standoff installation
1. Drill or punch a proper sized hole in to the
sheet metal.
2. Clamp the fastener above the standoff until
the hexagon head is embedded into the sheet.

Rivet nuts
When the material is thin, using rivet nuts is a simple and ideal
way of creating a threaded joint.
The rivet nut suits well for materials with thickness of 0.25 to
8.00 mm.
Available in different materials: Steel, aluminium and stainless
steel.
Thread range: M3 – M12
Shank models
Head models
Thru-holed or blind model
Round:
Pan head:
Thru-holed:
Most common when using normal load on
a steel sheet.
Most common when joint surface isn’t
required to be level.
Round, Rifled:
Flat head:
Most common when an efficient and strong
penetrating internal thread, without the need
for sealing, is required.
Grants higher torque resistance.
Hexagon:
Grants the highest torque resistance with
high loads.
Used when the joint surface needs to be
level.
Reduced Head:
Used when the joint surface needs to be
level with the sheet metal.
Tools
Tools are important when using rivet nuts. They are strong and easy to use. The
nosepiece and cap screw are easy to replace. A single tool suits for the installation
of various sizes. Easy to use manual, pneumatic and hydraulic tools are available
for use. The rivet nuts are placed into drilled or punched mount holes. The rivet nut
is then placed into the nosepiece manually or automatically, depending on the
type of the tool. When the jaw pusher is drawn out the non-threaded part of the
nut expands radially, thus riveting the nut into the material. Turning the cap screw
counter-clockwise releases the tool from the nut.
108
Blind:
Grants liquid proof sealing, which protects
the joint from corrosion or dirt. Important
when the joint is painted and the thread isn’t
protected.
