Professional Applications & Engineering Value

This No. 2 x 1/4" TRS thread forming screw is engineered to address common challenges in plastic fastening, such as material cracking, strip-out, and corrosion. The 18-8 stainless steel material provides excellent durability and resistance to rust, ideal for outdoor or humid conditions. Its Tri-Lobe shank and thread forming design displace plastic material to form strong, permanent threads, eliminating the need for inserts and reducing assembly steps. The Torx Plus drive (IP7/T7) ensures high torque transfer with minimal wear on drivers, enhancing efficiency in automated or high-volume production lines. Commonly used in electronics enclosures, automotive trim, and consumer products, this screw delivers reliable performance where vibration resistance and long-term integrity are critical.

Specification Summary & Compliance

This screw features a No. 2 size with a 1/4" length, 0.086" thread diameter, and 28 TPI fully threaded right-hand design. It adheres to standard inch measurements and includes a pan head with a rounded profile. Compliance is confirmed with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for hazardous substances.
