S-94065A242 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Secure spanner drive head prevents cam-out during high-torque applications, ensuring reliable fastening and minimizing tool damage.
• Full threading and pointed tip enables quick starts and smooth penetration through materials up to 0.025" thickness.
• Optimized drill bit compatibility with No. 21 (0.159") specification ensures precise hole preparation for maximum thread engagement.
• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for safe use in global industrial supply chains.
• Standard pan head profile provides a low-profile finish with excellent bearing surface for consistent clamping force.

Professional Applications & Engineering Value

These No. 10-12 x 1/2" 18-8 stainless steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design (A/AB type) eliminates the need for separate tapping operations, significantly reducing production time while creating stronger thread engagement than cutting alternatives. The drilled spanner drive accommodates specialized tools for high-torque applications where standard drives may fail, making these industrial fasteners ideal for machinery, enclosures, and structural components requiring vibration resistance. With fully threaded construction and right-hand threading, installation is streamlined while maintaining consistent clamping force across the entire engagement length.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.19" thread diameter and 12 threads per inch specification. The pan head features standard rounded profile with 0.373" diameter and 0.11" height. These tapping screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. Designed for use with No. 21 drill bit (0.159" diameter) for optimal performance in materials up to 0.025" maximum drilling thickness.
