Pittsburgh, PA – Triangle Fastener Corporation has announced the availability of its new #14-13 DP1 CONCEALOR® 304 Stainless Steel Bi-Metal Screws. It is available in four sizes to meet most application needs.

DP1 CONCEALOR® 304 Stainless Steel Bi-Metal Screws offer superior corrosion resistance and exceptional ductility, and feature a #2 square recess for optimal stability during installation. The screws’ buttress thread increases pullout loads and resistance to back-out compared to ordinary roofing screws. The screws are also TRI-SEAL® top-coated to improve tapping and reduce thread roll-over.

Product specifications and submittal are available at the Triangle Fastener website. The screw is suitable for fastening to metal, wood or concrete.
