S-94209A560 8-32 x 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black protective coating for extended service life in harsh industrial environments
• Exceptional torque transmission through Torx Plus IP20 drive system, reducing cam-out and tool wear
• Maximum holding power achieved through Tri-Lobe shank design that creates secure, vibration-resistant threads in soft materials
• Optimized for aluminum, brass, and copper applications with thread forming design that eliminates chip formation
• Precise dimensional control with length tolerance of -0.03" to 0" ensuring consistent installation performance
• Coarse UNC threading provides rapid installation and strong pull-out resistance in soft metals
• Full regulatory compliance with RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These 8-32 UNC thread forming screws deliver exceptional engineering value in aluminum, brass, and copper assemblies where traditional fastening methods often fail. The Tri-Lobe shank cross-section displaces material during installation, creating permanent, high-strength threads without generating metal chips that can compromise electrical components or precision mechanisms. The black corrosion-resistant coated steel construction ensures long-term reliability in demanding environments, while the Torx Plus drive system provides superior torque transmission, eliminating the stripping issues common with Phillips or slotted drives. Engineered specifically for No. 29 drill bit preparation (0.136" diameter), these thread forming tapping screws offer predictable, repeatable performance in automated assembly operations and maintenance applications across electrical enclosures, HVAC systems, and industrial machinery.

Specification Summary & Compliance

These No. 8 tapping screws feature 8-32 UNC coarse threads with right-hand direction and fully threaded blunt tip design. Manufactured to precise dimensional standards with 1" length tolerance of -0.03" to 0" and 0.164" thread diameter. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The thread forming tapping method and standard rounded pan head profile provide reliable performance in accordance with industrial fastening specifications for soft metal applications.
