- Secure fastening in plastic materials with TRS type and blunt tip, minimizing cracking or stress damage during installation.
- Easy installation and removal thanks to the Phillips No. 1 drive and standard pan head, providing a reliable grip with common tools.
- Consistent performance with fully threaded M4 x 8mm metric sizing and 1.79mm pitch, ensuring uniform holding power.
- Compliance with industrial safety standards including RoHS 3 and REACH, supporting sustainable and safe manufacturing practices.
- Versatile for various plastic applications, from electronics to automotive assemblies, due to its durable and non-corrosive properties.
Professional Applications & Engineering Value
This M4 x 8mm TRS tapping screw is engineered to address common challenges in plastic fastening, such as material stress and assembly inefficiencies. Made from 18-8 stainless steel, it resists rust and corrosion, ideal for outdoor or high-moisture settings. The thread-forming design creates strong, permanent threads in plastics without pre-drilling, reducing labor and part failure. With a Phillips drive and pan head, it ensures quick, tool-compatible installation, while the blunt tip prevents splitting in brittle plastics. Perfect for industrial applications like electronics enclosures and automotive components, it enhances durability and streamlines production lines.
Specification Summary & Compliance
This screw features metric M4 size with 8mm length, fully threaded with an approximate pitch of 1.79mm, and a standard pan head profile (7mm diameter, 2.8mm height). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use. Designed for thread-forming applications in plastics, it requires a No. 30 drill bit (0.1285" diameter) for optimal performance.
