Kwikseal Woodbinder - #10 diameter 1/4" Hex Washer Head fastener is designed to attach steel roofing and siding used in post-frame & residential metal roofing applications. Threads transition from fine to coarse to generate superior holding strength in various wood substrates. Sharp Point and pronounced lead thread consistently drills high tensile 29 & 26 gauge steel with no "point walking." EPDM rubber is vulcanized to a steel washer to form an excellent seal, even when driven at an angle. Kwikseal Stitch screws are also available.

This bonded sealing washer will completely cover existing hole, even if elongated by movement in the metal roof.

It is also used to attach steel roofing used in post-frame and residential construction.
