S-90184A450 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Optimized for 0.1875" drill bits ensures precise fit and maximum holding power in sheet metal up to 0.025" thickness.
• Reliable Phillips drive (No. 3 size) provides secure torque transmission and prevents cam-out during high-speed assembly.
• Fully threaded shank and pointed tip for faster starting, easier alignment, and consistent engagement across the entire fastener length.
• Standard pan head profile offers a low-profile finish with good bearing surface for secure fastening in confined spaces.
• Full regulatory compliance with RoHS 3 and REACH standards, ensuring safety and environmental responsibility for global supply chains.

Professional Applications & Engineering Value

This thread forming tapping screw is specifically engineered to solve common fastening challenges in sheet metal applications, where material integrity and joint reliability are critical. The 316 stainless steel composition provides exceptional resistance to chlorides, acids, and industrial chemicals, preventing failure in corrosive environments like marine, chemical processing, and food equipment. The thread forming (Type A/AB) design displaces material rather than cutting it, creating zero chips and stronger, vibration-resistant threads that won't loosen under dynamic loads. With its fully threaded construction and Phillips drive, installers achieve faster drive times and consistent clamp force, making it ideal for high-volume production lines in HVAC, electronics enclosures, and automotive assemblies where speed and durability are paramount.

Specification Summary & Compliance

This No. 12 x 5/8" tapping screw features a 0.216" thread diameter with 11 threads per inch and standard Class 2A inch-series tolerances for consistent fit. The pan head design has a 0.425" diameter and 0.151" height with a rounded profile. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for industrial safety standards worldwide.
