Professional Applications & Engineering Value
Engineered for steel and sheet metal applications, this corrosion-resistant coated steel tapping screw addresses critical industrial challenges. The thread forming design creates precise mating threads without generating chips, eliminating contamination risks in sensitive assemblies. With its integrated sealing washer combining steel strength and rubber flexibility, the fastener provides both mechanical security and environmental protection against moisture ingress. The drill tip configuration penetrates up to 0.21" thickness, streamlining installation in fabrication, HVAC, and structural applications where pre-drilling isn't feasible. This BSD tapping screw delivers reliable performance in right-hand threaded assemblies requiring repeated disassembly and reassembly cycles.
Specification Summary & Compliance
This 1/4"-14 fully threaded tapping screw features precision Class 2A thread tolerances with right-hand threading and external hex drive configuration. The fastener meets BSD tapping screw standards for thread forming applications in metallic substrates. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental responsibility while maintaining the mechanical properties required for industrial fastening applications. The integrated flat washer (0.563" OD) combines steel and rubber materials for optimal sealing performance.
