• Streamlined assembly process with a fully threaded, blunt tip design that forms precise, strong threads without pre-tapping.
• Reliable material compatibility specifically engineered for use in various plastics, minimizing stress cracking and ensuring a secure fit.
• Broad industrial compliance meeting RoHS 3 and REACH regulations, making them suitable for global supply chains and sensitive applications.
• Precise M4.55 x 10mm metric sizing with a 1.59mm pitch, offering dimensional accuracy for consistent performance in automated or manual assembly.

Professional Applications & Engineering Value

This M4.55 TRS thread-forming screw is engineered to address common challenges in plastic assembly, such as material stress and loosening under vibration. The 18-8 stainless steel material provides excellent durability and corrosion resistance, while the Tri-Lobe shank and thread-forming action displace plastic material to create strong, permanent threads without chips. This design eliminates the need for pre-tapped holes, reducing assembly steps and potential failure points. The Torx Plus IP20 drive ensures high torque transfer with minimal wear, making it ideal for high-volume production lines in electronics, automotive components, and consumer appliances where reliability and vibration resistance are critical.

Specification Summary & Compliance

This screw features a metric M4.55 size with a 10mm length and 1.59mm thread pitch, designed as a thread-forming TRS type with a Tri-Lobe shank for plastic applications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for industrial use where environmental and safety standards are mandatory.
