NOTE: To be used in low carbon steels,
aluminum and stainless steels in an annealed
condition RB85 or softer.
Installation
NOTE: For inner panels less than 1.3 (.051) thick,
the retainer will create a small gap. To select the
proper stud, assume the inner panel thickness as
1.3 (.051).
2. Press receptacle into hole until shoulder

ADJUSTMENT CALCULATION
To determine your total material
thickness, substitute 1.3 (.051) for
frame thickness if frame thickness
is less than 1.3 (.051).
3. To select proper stud grip, determine
total panel thickness and select stud
from corresponding stud selection table.

condition RB85 or softer.
Installation
NOTE: For inner panels less than 1.3 (.051) thick,
the retainer will create a small gap. To select the
proper stud, assume the inner panel thickness as
1.3 (.051).
2. Press receptacle into hole until shoulder

ADJUSTMENT CALCULATION
To determine your total material

frame thickness if frame thickness
is less than 1.3 (.051).

condition RB85 or softer.
Installation
NOTE: For inner panels less than 1.3 (.051) thick,
the retainer will create a small gap. To select the
proper stud, assume the inner panel thickness as
1.3 (.051).

Choosing a Quarter-turn Fastener Assembly
1. Choose your receptacle (note any frame thickness limitations)
2. Choose your stud (or ”headstyle” type)
• Measure your Outer Panel Thickness or Total Material Thickness (chart on page 5 lists range of thickness
by receptacle and will tell you to use either Outer Panel Thickness or Total Material Thickness)
• Apply adjustment calculation to your measurement if listed next to receptacle drawings
• Utilize measurement (or adjusted calculation) to locate stud part number in table
3. Choose your retainer
Retainer
Stud
Receptacle
To fasten, apply 1/4 turn to the stud. The stud now engages with the
installed receptacle and secures both panels.

By applying a 1/4 turn to the stud in the opposite direction, the stud
disengages with the receptacle, but remains captive for future use.

Adjustment Calculation:
In typical applications, an installed stud is used to fasten an outer panel
with an inner panel (frame). An installed receptacle is permanently
installed to the inner panel. The stud is held captive in the outer panel
with a retainer.

• Utilize measurement (or adjusted calculation) to locate stud part number in table
3. Choose your retainer
