— WSNTL51E is superceded by WSV51E
All screws are supplied in box quantities only. free 'bit' supplied with every box of screws
The WSV is the new improved subfloor screw from Simpson Strong-Tie. The subfloor screws have been re-engineered to reduce driving force and increase installation speed. Less installation torque means reduced wear on tools. WSV screws have a sharp point with an aggressive variable thread resulting in faster, smoother installations. The deep T25 6-lobe recess provides improved control and greater bit life whilst the ribbed head design countersinks easily providing a clean, flush finish.
