A free-rotating, permanently attached washer distributes holding pressure over a wider area than a flange and remains stationary to prevent scratching the material surface as you tighten the screw.

Thread-forming screws press threads into drilled holes for a tight, vibration-resistant assembly.

Alternating high and low threads minimize driving torque and allow the screw to hold more material between threads for a stronger hold and better strip-resistance than standard drywall screws for wood.

Hold sheets of drywall together until glue sets

Attach metal framing to metal studs up to 0.036" thick.

With a square-drive head, these screws attach drywall to metal studs up to 0.036" thick. The head is one-third smaller than other drywall screws.

These square-drive screws have a drill point that powers through drywall and into metal studs up to 0.105" thick. Heads are one-third smaller than those of other drywall screws.
