S-93406A291 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• Secure sheet metal fastening through thread forming technology that creates strong, reliable threads without chips or debris
• Enhanced bearing surface with wide truss head design distributes load effectively and prevents pull-through in thin materials
• Optimized driving efficiency with No. 3 Phillips drive that provides excellent torque transfer and reduces cam-out risk
• Full-length threading ensures maximum grip along the entire 1/2" length for superior holding power in sheet metal assemblies
• Precision thread engagement with 11 TPI and 0.216" diameter delivers consistent performance in pre-drilled 3/16" holes
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These 316 stainless steel tapping screws solve critical challenges in sheet metal fabrication and industrial assembly. The thread forming design eliminates tapping operations by cold-forming mating threads directly into pre-drilled materials, preventing metal chips that could contaminate sensitive equipment. With their rounded truss head profile and wide bearing surface, these Phillips drive screws provide exceptional clamp force distribution while resisting vibration loosening. The fully threaded No. 12 screw with 11 threads per inch ensures maximum thread engagement in materials up to 0.025" thickness, making them ideal for HVAC systems, electrical enclosures, and automotive components where corrosion resistance and structural integrity are paramount.

Specification Summary & Compliance

This thread forming tapping screw features precision Class 2A thread tolerances with 0.216" diameter and 11 TPI thread pitch conforming to A/AB tapping screw standards. The manufacturing process ensures consistent fully threaded design with pointed tip for easy starting in pre-drilled 0.1875" holes. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance adherence for industrial applications.
