Professional Applications & Engineering Value

This M5 tapping screw is engineered to address common challenges in plastic fastening, such as cracking and stripping, by utilizing a thread-forming (TRS) design that creates strong, permanent threads without pre-drilled tapping. The 18-8 stainless steel material provides excellent durability against corrosion and mechanical stress, making it ideal for industrial assemblies in electronics, automotive, and consumer goods. With a Phillips pan head and blunt tip, it ensures easy installation and minimizes plastic deformation, while the fully threaded shank and precise 2.24 mm pitch enhance grip and load distribution. This screw is a reliable choice for plastic applications requiring high performance and regulatory compliance.

Specification Summary & Compliance

This M5 x 20 mm tapping screw features metric dimensions with a rounded pan head (8.8 mm diameter, 3.32 mm height) and Phillips No. 2 drive. It is manufactured to thread-forming (TRS) standards with a right-hand thread direction and approximate 2.24 mm pitch for consistent performance. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial use.
