The ICC-ES ESR-1472 code-listed Strong-Drive WSNTL Subfloor screw has a unique thread pattern that allows for quick and seemingly effortless installations. With lateral, shear and withdrawal values that exceed those of 10d common nails, the holding power of the WSNTL screw eliminates the gaps between the joist and subfloor that cause floor squeaks. The WSNTL Subfloor screw countersinks easily and backs out smoothly, allowing for easy future access to floor cavities. Quik Drive screws are specifically designed for use in our attachments to ensure problem-free system performance. The patented curved collation strips hold the screws up and away from the work surface, making moving and positioning the tool easier.
