Professional Applications & Engineering Value

These black epoxy coated steel tapping screws deliver exceptional performance in steel, insulation, and sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the need for separate tapping operations, significantly reducing installation time while creating stronger thread engagement through material displacement. The drilling tip design combined with partial threading allows for precise depth control and prevents material splitting in thin-gauge applications. With FM Approved certification, these industrial fasteners meet stringent safety requirements for construction and manufacturing environments, providing reliable, long-lasting connections in HVAC systems, building envelopes, and equipment assemblies where vibration resistance and environmental protection are critical.

Specification Summary & Compliance

These tapping screws feature precision 0.255" thread diameter with 13 TPI right-hand threads and Class 2A thread tolerances for consistent performance. The manufacturing process adheres to FM Approved specifications for quality assurance, while the black epoxy coating provides enhanced corrosion protection meeting industrial standards. The partially threaded design with 4" thread length on a 10" shank ensures optimal fastening in various material thicknesses. Compliance includes meeting relevant industrial fastening standards for construction and manufacturing applications.
