- Corrosion-resistant zinc-plated steel construction ensures long-term durability and reliability in various industrial environments.
- Efficient installation with Phillips No. 2 drive provides common tool compatibility and reduces cam-out during fastening.
- Clean, flush finish thanks to the standard flat head with 82° countersink angle, ideal for applications requiring a smooth surface.
- Reliable thread engagement from fully threaded design and blunt tip, enabling consistent performance in plastic materials.
- Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries.
- Optimized for plastic assembly with specified drill bit size (No. 15), reducing preparation time and improving installation accuracy.
Professional Applications & Engineering Value
These No. 10 x 1/2" zinc-plated steel TRS tapping screws are engineered to address common challenges in plastic assembly, such as material cracking and poor thread retention. The thread forming action of the Tri-Lobe shank creates strong, lasting threads in plastic without generating chips, minimizing failure risks. The Phillips drive and flat head design ensure easy installation and a flush finish, critical for consumer electronics, automotive trim, and appliance manufacturing where aesthetics and reliability are paramount. The zinc-plated finish provides essential corrosion resistance, extending service life in demanding conditions.
Specification Summary & Compliance
This screw features a No. 10 size with 1/2" length, 0.19" thread diameter, and 14 TPI fully threaded right-hand design. It complies with standard inch measurements and is designed for use with a No. 15 drill bit (0.18" diameter). The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring adherence to environmental and safety regulations for industrial components.
