The WSHL is designed to work with the Simpson Strong-Tie Quik Drive auto-feed screw driving system. This screw is ideal for securely fastening subfloor panels to floor joists. The Quik Drive system features non-skid teeth that provide increased stability resulting in uniform toenailing and countersink on slick surfaces.
