S-90184A158 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• Effortless installation through thread forming design that creates strong, permanent threads without chip removal
• Secure fastening in sheet metal with precise No. 32 drill bit compatibility (0.116" diameter) for optimal grip in materials up to 0.025" thickness
• Enhanced drive stability with Phillips No. 2 drive system, reducing cam-out and ensuring consistent torque application
• Maximum thread engagement with fully threaded 1-1/4" length and 18 TPI configuration for superior holding power
• Low-profile rounded pan head provides smooth finished appearance while maintaining adequate drive contact surface
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

This 316 stainless steel tapping screw delivers exceptional performance in sheet metal fabrication and industrial assembly applications where corrosion resistance is critical. The thread forming design eliminates tapping operations by cold-forming mating threads directly into materials, creating stronger thread engagement than conventional cutting screws. The Phillips pan head configuration offers reliable drive transfer while maintaining a low profile for space-constrained assemblies. Engineered specifically for sheet metal applications with precise drill bit sizing (No. 32), these screws prevent material distortion and provide consistent clamping force in panels up to 0.025" thickness. The 18 TPI thread pitch ensures optimal thread density for secure fastening in thin-gauge materials commonly used in HVAC, electronic enclosures, and automotive components.

Specification Summary & Compliance

This No. 6 x 1-1/4" tapping screw features standard Class 2A thread tolerances with right-hand threading and A/AB tapping screw type specifications. The fully threaded design with 18 TPI provides complete thread engagement along the entire shank length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors. The screw is optimized for use with No. 32 drill bits (0.116" diameter) in materials with maximum drilling thickness of 0.025".
