SAFETY
The washer is designed to ensure the
screw insertion at precisely 45° to the
plane and the connector feed in the
correct direction
EASE OF HANDLING
The regular cylindrical shape of the
diameter external to the countersink and
the anti-slip knurling assure a firm grip
during the assembling phase
AESTHETICS
The perfect matching between VGS
head and the countersunk washer
creates a compact and aesthetically
pleasing joint finish.

* For thicker plates it is necessary to realize a countersink in the lower part of the steel plate.
For VGS screw-lengths > 300 mm a Ø5 predrill is recommended.
The assembly must be performed so as to guarantee that the stress is evenly distributed
among all the installed VGU washers.

GENERAL PRINCIPLES
NOTES
• Charatteristic values consistent with EN 1995:2008 and in accordante with
ETA-11/0030.
• Admissible values are obtained according to DIN 1052:1988.
• For the calculation process a timber density of ρk = 380 kg/m3
has been considered.
• The fastener pull-out strength has been evaluated by considering a
45° angle to the grain and an effective length of the threaded part equal to Sg.
(1) The design shear strength of the joint is the minimum among the timber
design shear strength (RV,d) and the steel design shear strength (Rtens,d 45°).
For the correct realization of the joint, the fastener head should be fully
embedded into the VGU washer. For intermediate values of SPLATE linear
interpolation is allowed. Dimensioning and verification of timber elements
and steel plates shall be carried out separately.
