S-90925A203 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Enhanced torque transmission through T20 Torx drive design, reducing cam-out and tool slippage during installation
• Reliable thread forming capability creates strong, permanent threads in sheet metal without pre-tapping requirements
• Full 1-1/2" threading provides maximum grip length and uniform stress distribution across the entire fastener
• Optimized pan head design offers excellent bearing surface while maintaining a low-profile appearance
• Precision No. 8-15 thread configuration ensures perfect engagement with 0.164" diameter and 15 threads per inch
• Comprehensive regulatory compliance with RoHS 3 and REACH standards for global market acceptance

Professional Applications & Engineering Value

These No. 8 sheet metal tapping screws deliver exceptional performance in thread forming applications where traditional fastening methods fall short. The zinc-plated steel construction provides reliable corrosion protection for HVAC systems, electrical enclosures, and automotive assemblies. The T20 Torx drive system eliminates common installation issues like screw head stripping, while the thread forming technology creates stronger connections by displacing material rather than removing it. This A/AB screw type is specifically engineered for 0.025" maximum drilling thickness applications, making it ideal for thin-gauge sheet metal work where pull-out resistance is critical. The fully threaded design ensures consistent clamping force distribution, preventing material distortion and maintaining structural integrity in vibration-prone environments.

Specification Summary & Compliance

These sheet metal tapping screws feature precision No. 8-15 thread configuration with 0.164" thread diameter and 15 threads per inch, manufactured to exacting dimensional standards. The fasteners are compatible with No. 29 drill bit (0.136" diameter) for optimal hole preparation. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and market acceptance. The thread forming tapping method and right-hand threading provide reliable performance in various industrial applications.
