S-90935A310 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel construction, ideal for demanding industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping
• Optimized for 3/16" drill bits with precise 0.1875" diameter compatibility for consistent installation
• Maximum material penetration with pointed tip and fully threaded shank ensuring secure fastening in 0.025" maximum thickness materials
• Reliable Phillips drive system (No. 3 size) provides excellent torque transfer and prevents cam-out during installation
• Industry-compliant performance meeting RoHS 3 and REACH environmental standards for global manufacturing applications
• Standard pan head design offers low-profile installation with improved bearing surface for sheet metal assemblies

Professional Applications & Engineering Value

These No. 12 x 1" Black-Oxide Steel Phillips Pan Head tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and long-term reliability are critical. The thread forming design (A/AB type) displaces material rather than removing it, creating stronger thread engagement that resists loosening under stress. With 0.216" thread diameter and 11 threads per inch, these right-hand threaded screws provide optimal pull-out strength while the black-oxide surface treatment enhances corrosion protection in harsh environments. The combination of fully threaded construction and pointed tip ensures rapid startup and consistent seating in materials up to 0.025" thickness, making them ideal for HVAC systems, electrical enclosures, and automotive assemblies where precision fastening is essential.

Specification Summary & Compliance

These thread forming sheet metal screws feature precise dimensional specifications including 0.216" thread diameter, 11 threads per inch, and 1" length with standard inch system tolerances. Manufactured to A/AB tapping screw standards with fully threaded right-hand configuration and pan head profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications while maintaining consistent performance in sheet metal fastening operations.
