S-94061A157 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 industrial environments
• Efficient installation with integrated No. 3 drill tip that eliminates pre-drilling, saving time and labor costs
• Maximum material penetration with 0.21" drilling thickness capability for secure fastening in steel and sheet metal applications
• Enhanced drive stability through Phillips No. 3 drive system that reduces cam-out and improves torque transmission
• Secure thread formation with BSD thread forming design that creates strong, permanent threads without chip removal
• Complete fastening coverage with fully threaded shank design that ensures consistent holding power along the entire length
• Professional finished appearance with standard oval head profile that sits flush with material surfaces

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where reliability is critical. The specialized thread forming technology (BSD type) creates permanent, high-strength threads by displacing material rather than cutting it, eliminating metal chips that can compromise electrical systems or moving parts. The integrated drill tip with No. 3 geometry penetrates up to 0.21" thickness without pilot holes, significantly reducing installation time in production environments. The zinc-plated finish provides essential corrosion protection for industrial settings, while the Phillips drive system ensures secure tool engagement during high-torque applications. The fully threaded design maintains consistent clamping force across the entire 1-1/2" length, preventing loosening under vibration and thermal cycling.

Specification Summary & Compliance

These tapping screws feature precise No. 12 screw size with 0.216" thread diameter and 14 threads per inch in right-hand orientation. The BSD thread forming design follows industry standards for self-tapping fasteners, while the 82° countersink angle ensures proper seating with the oval head profile. Manufacturing complies with standard inch system tolerances for consistent performance. The zinc-plated steel construction meets industrial requirements for corrosion resistance and mechanical strength in demanding applications.
