Sealtite Building Fasteners

WOODBINDER ® ST-XL

• Designed as an alternative to the zinc-aluminum alloy head. It is also used to attach steel roofing used in post-frame & residential construction. The smaller cupped HWH provides an attractive low-profile appearance versus larger HWH fasteners.

• 304 Stainless Steel cap provides lifetime warranty against red rust on the head & washer. You may obtain a free copy of the written warranty upon request.

• ST-XL is an excellent choice for GALVALUME or other long-life metal roofs.

• The combination of a sharp point & Type 17 drills 29 & 26 gauge consistently & eliminates the metal shavings that can embed themselves in the EPDM rubber washer.
