S-93406A203 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments
• Enhanced load distribution from the wide truss head design, reducing material stress and preventing pull-through in sheet metal applications
• Efficient thread forming installation creates strong, permanent threads without chips, eliminating the need for separate tapping operations
• Optimized sheet metal penetration with pointed tip and fully threaded shank for quick starts and maximum thread engagement
• Secure Phillips No. 2 drive compatibility provides reliable torque transfer while minimizing cam-out during installation
• Precision No. 29 drill bit compatibility ensures proper hole sizing for optimal thread formation and holding power
• Full regulatory compliance with RoHS 3 and REACH standards, meeting international environmental and safety requirements

Professional Applications & Engineering Value

This No. 8-15 thread forming tapping screw delivers exceptional engineering value for sheet metal fabrication and assembly operations. The 18-8 Stainless Steel composition provides excellent corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor elements. The wide truss head design significantly increases bearing surface area, distributing clamping force over a larger area to prevent deformation of thin sheet materials. The thread forming tapping method (Type A/AB) cold-forms mating threads in the base material, creating stronger connections than cut threads while eliminating chip removal concerns. With full threading and a pointed tip, installation is streamlined, reducing assembly time and labor costs in high-volume production environments.

Specification Summary & Compliance

This tapping screw features precision No. 8-15 thread specifications with 0.164" diameter and 15 threads per inch, ensuring consistent performance across applications. The 1-1/2" length provides ample engagement for various material thicknesses. Manufactured to industry standards for thread forming screws, it demonstrates compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance adherence. The screw is engineered for use with No. 29 drill bits (0.136" diameter) and accommodates maximum drilling thickness of 0.025" in sheet metal applications.
