Sealtite Building Fasteners

STEELBINDER® MAXX SELF DRILL®

• Fastener designed to attach metal roof and sidewall panels used in pre-engineered metal building applications.

• #12 Diameter 5/16 Cupped HWH self-drilling fastener easily penetrates steel up to .210 in thickness with no "point walking". 1/4 Stitch will securely fasten 2 layers of 26 GA with no strip-out.

• Mechanical zinc plating provides superior corrosion resistance versus electro-plating under barrier coatings.

• Cupped head & washer encapsulate EPDM rubber washer & provide a secure seal even when driven at an angle.
