S-90190A077 Length 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Excellent thread-forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapped holes
• Optimized Phillips drive design (No. 1 size) provides secure tool engagement and reduces cam-out during installation
• Fully threaded 5/16" length with 32 TPI ensures maximum grip length and holding power in thin materials
• Low-profile pan head design offers a finished appearance while maintaining sufficient drive torque capacity
• Precision-engineered pointed tip facilitates easy starting and alignment in sheet metal applications
• Compliance with major environmental regulations including RoHS 3 and REACH for global manufacturing acceptance

Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and installation efficiency are critical. The thread forming technology (A/AB type) creates strong, permanent threads by displacing material rather than cutting it, eliminating chip-related contamination issues in electrical assemblies and precision equipment. The combination of 0.086" thread diameter and 32 threads per inch provides optimal balance between thread engagement strength and material integrity in thin gauges. The zinc plating delivers essential corrosion protection for industrial environments, while the Phillips pan head design ensures consistent clamping force distribution and streamlined assembly processes in high-volume manufacturing operations.

Specification Summary & Compliance

These thread forming tapping screws feature precision Class 2A thread tolerances with 0.086" thread diameter and 32 TPI in right-hand orientation. The 5/16" fully threaded design with standard pan head profile (0.167" diameter, 0.062" height) ensures consistent performance across applications. Manufactured to A/AB tapping screw standards for sheet metal, these fasteners are compatible with No. 48 drill bits (0.076" diameter) for optimal hole preparation. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures they meet current industrial safety and sustainability requirements.
