• Optimized compatibility with No. 21 drill bits (0.159" diameter), simplifying hole preparation and improving installation accuracy.

Professional Applications & Engineering Value

These M5 TRS tapping screws are specifically engineered for plastic assembly challenges, where traditional fasteners may strip threads or cause material stress. The 18-8 stainless steel offers excellent resistance to rust and chemicals, ideal for outdoor equipment, electronics enclosures, and automotive components exposed to moisture. The thread-forming (TRS) design displaces plastic material to form precise, load-bearing threads, eliminating the need for inserts and reducing part count. With a Phillips flat head and 90° countersink, these screws sit flush to prevent interference and enhance aesthetics in consumer products. Fully threaded and with a blunt tip, they minimize cracking in brittle plastics while providing uniform clamping force, making them a reliable choice for high-volume manufacturing and maintenance repairs.

Specification Summary & Compliance

This metric M5 x 14mm screw features a standard thread pitch of 2.24mm and is fully threaded for consistent performance. It adheres to common industrial tolerances for thread-forming screws in plastic applications. The product is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted hazardous substances and safe for use in various markets. Designed for use with a No. 21 drill bit (0.159" diameter) and a 90° countersink angle, it supports efficient, precise installations in compliance with industry best practices.
