Professional Applications & Engineering Value
This No. 8 x 5/16" stainless steel tapping screw is specifically engineered to address common challenges in plastic assembly, such as stress cracking and strip-out. The thread forming (DST type) action displaces material to create robust, load-bearing threads without generating chips, making it perfect for electronics enclosures, automotive trim, and consumer appliances. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance, ensuring long-term reliability even in harsh conditions. The combination of a Phillips drive and blunt tip allows for quick, straightforward installation while preserving the integrity of the plastic substrate, reducing waste and improving production efficiency.
Specification Summary & Compliance
This screw features a thread diameter of 0.164" with 18 TPI and a length of 5/16", adhering to standard inch measurements for precise fit. The fully threaded shank and right-hand thread direction ensure consistent engagement. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing compliance with environmental and safety standards for industrial use.
