Professional Applications & Engineering Value

This No. 10 x 5/8" Phillips flat head tapping screw is engineered to address common challenges in plastic assembly, where material cracking and strip-out are frequent issues. The 18-8 stainless steel provides excellent strength and corrosion resistance, while the TRS thread forming design with a Tri-Lobe shank cross-section displaces plastic material without cutting, creating strong, vibration-resistant threads. This reduces the need for additional inserts and minimizes assembly time. Ideal for applications in electronics, automotive components, and consumer goods, the screw’s fully threaded profile and standard flat head ensure a secure, flush fit, enhancing both aesthetic and functional integrity in demanding environments.

Specification Summary & Compliance

The screw features a thread diameter of 0.19" with approximately 14 threads per inch, adhering to standard inch measurements for precision. It is designed for use with a No. 21 drill bit and an 82° countersink angle, ensuring proper fit in plastic materials. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
