Professional Applications & Engineering Value
This No. 1 TRS tapping screw is specifically engineered for plastic fastening applications, where traditional screws may cause material failure. The 18-8 stainless steel provides excellent corrosion resistance, making it suitable for outdoor equipment, electronic enclosures, and automotive components exposed to moisture. The thread forming action with a Tri-Lobe shank displaces plastic material without cutting, which minimizes internal stress and reduces the risk of boss cracking—a common issue in plastic assembly. Combined with a Phillips drive and blunt tip, it ensures easy installation and secure holding power, enhancing productivity in high-volume manufacturing while meeting strict RoHS and REACH compliance for global supply chains.
Specification Summary & Compliance
This screw features a thread diameter of 0.073" with 32 TPI and a length of 1/2", designed for use with a No. 53 drill bit (0.0595" diameter). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances. The thread forming (TRS) design and right-hand threading provide reliable performance in plastic materials, with full threading for consistent grip. Manufactured to precise standards, it offers dependable fastening in industrial applications.
