S-90315A432 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Optimized Phillips drive and oval head provides secure tool engagement and a flush, professional finish that minimizes snagging.
• Precise dimensional compatibility with No. 32 drill bit (0.116") and 82° countersink angle for seamless integration into standard sheet metal assemblies.
• Full RoHS 3 and REACH compliance guarantees environmental safety and meets stringent international regulatory standards.
• High thread density (18 TPI) delivers enhanced grip and vibration resistance in thin materials up to 0.025" thickness.
• Versatile right-hand threading ensures easy installation and reliable performance in various sheet metal fabrication applications.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are critical. The thread forming Type A/AB design eliminates the need for separate tapping operations by cold-forming mating threads directly into the material, preventing stripping and ensuring superior pull-out strength. The Phillips oval head sits flush with surfaces, reducing protrusion risks in assembled products. Ideal for HVAC systems, electronic enclosures, and automotive panels, these screws provide reliable fastening in thin-gauge materials while maintaining compliance with industrial safety standards through their RoHS and REACH compliant composition.

Specification Summary & Compliance

This No. 6 x 7/8" tapping screw features standard inch measurements with 0.138" thread diameter and 18 threads per inch for precise fitment. Manufactured to Type A/AB thread forming specifications with fully threaded shank and pointed tip for easy starting. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability. The oval head design incorporates an 82° countersink angle for proper seating in prepared holes using No. 32 drill bits.
