S-90048A196 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Excellent thread-forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Optimized 82° countersink angle ensures flush installation and prevents snagging in sheet metal assemblies
• Maximum holding power through fully threaded design that distributes load evenly across the entire fastener length
• Quick and secure installation with Phillips No. 2 drive that prevents cam-out and speeds assembly processes
• Precise compatibility with standard No. 29 drill bits (0.136" diameter) for consistent, reliable hole preparation
• Reliable performance in materials up to 0.025" thickness, making them ideal for various sheet metal gauges

Professional Applications & Engineering Value

These No. 8-15 thread forming tapping screws deliver exceptional engineering value in sheet metal applications where vibration resistance and permanent fastening are critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the thread forming design eliminates the need for separate tapping operations, reducing assembly time and costs. The Phillips flat head configuration ensures smooth, flush surfaces that won't interfere with adjacent components. With 15 threads per inch and 0.164" thread diameter, these screws create strong, reliable threads in sheet metal up to 0.025" thickness, making them ideal for HVAC systems, electrical enclosures, automotive panels, and machinery guards where secure, long-lasting fastening is paramount.

Specification Summary & Compliance

This No. 8-15 x 5/8" tapping screw features precision Class 2A thread tolerances and conforms to A/AB tapping screw standards for consistent performance. The right-hand threaded, fully threaded design with pointed tip ensures easy starting and maximum thread engagement. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental responsibility and industrial safety standards. The standard flat head profile with 82° countersink angle and compatibility with No. 29 drill bits (0.136" diameter) ensures proper installation in sheet metal applications requiring reliable, permanent fastening solutions.
