S-90056A199 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Excellent thread-forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapping requirements
• Optimized drive efficiency with No. 2 Phillips head providing secure tool engagement and reduced cam-out during installation
• Maximum material engagement through full threading and 18 TPI design ensures superior holding power in thin-section applications
• Streamlined installation process with blunt tip and thread forming Type B design that displaces material rather than removing it
• Reliable performance compliance meeting RoHS 3 environmental standards for use in regulated industrial applications
• Versatile pan head design offers low-profile fastening with improved bearing surface for sheet metal assemblies

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value for sheet metal applications where reliable fastening is critical. The thread forming Type B technology creates strong, permanent threads by displacing material rather than cutting it, eliminating chips and ensuring full thread engagement in thin materials. The Phillips pan head design with No. 2 drive size provides optimal torque transfer while maintaining a low profile for space-constrained assemblies. With full threading and 18 TPI, these screws distribute clamping force evenly, preventing loosening under vibration and thermal cycling. The combination of zinc plating corrosion protection and RoHS 3 compliance makes them ideal for electronics enclosures, HVAC systems, automotive components, and industrial equipment where environmental regulations and durability are paramount concerns.

Specification Summary & Compliance

This No. 8 x 1" tapping screw features precise 0.164" thread diameter with 18 TPI fully threaded design and Class 2A thread fit for reliable engagement. The screw meets thread forming Type B specifications for sheet metal applications, requiring No. 29 drill bit (0.136" diameter) for proper installation. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental responsibility while maintaining industrial-grade performance standards for corrosion resistance and mechanical strength in demanding fastening applications.
