• Precision compatibility with a No. 53 drill bit (0.0595" diameter), ensuring accurate pilot holes and reliable fastening in plastic assemblies.
• Compliance with environmental regulations, meeting RoHS 3 and REACH standards for safe use in industrial and consumer products.
• Consistent performance with a standardized pan head and right-hand threads, enabling repeatable installations in high-volume production.

Professional Applications & Engineering Value

This No. 1 TRS thread forming screw is engineered to address common challenges in plastic fastening, such as material cracking and stripped threads. The 18-8 stainless steel offers excellent durability against corrosion, while the tri-lobe shank and thread forming design displace plastic material to create strong, permanent threads without pre-tapping. This reduces assembly time and tool wear, making it ideal for plastic assembly in electronics, automotive trim, and consumer goods. The Phillips drive ensures straightforward installation with standard tools, and the fully threaded 3/8" length provides uniform clamping force, enhancing joint integrity in demanding applications.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.073" and 32 TPI for precise fit. It is designed as a TRS (Thread Rolling Screw) type for use in plastics, requiring a No. 53 drill bit for pilot holes. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
