  • Secure and stable fastening with a fully threaded blunt tip, minimizing the risk of plastic cracking during assembly.
  • Easy installation with Phillips No. 0 drive, providing reliable torque transfer and reducing cam-out risks.
  • Pre-engineered compatibility using a standard No. 56 drill bit (0.0465"), streamlining your assembly process.
  • Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in global markets.
  • Compact and versatile design with a 1/8" length and 0.06" thread diameter, ideal for tight spaces in plastic components.

Professional Applications & Engineering Value

This TRS tapping screw is specifically engineered for plastic applications, where traditional fasteners often cause material failure. The 18-8 stainless steel offers excellent durability and resistance to oxidation, while the Tri-Lobe shank cross-section and thread forming method displace plastic material to create strong, permanent threads without pre-tapping. This design reduces assembly time and tool wear, making it ideal for high-volume production in electronics, automotive trim, and consumer goods. The Phillips drive ensures consistent installation, and the blunt tip prevents damage to delicate plastic structures, providing a reliable fastening solution that enhances product lifespan.

Specification Summary & Compliance

This screw features a thread diameter of 0.06" with approximately 42 threads per inch and a right-hand thread direction. It complies with standard inch measurements and is designed for use with a No. 56 drill bit (0.0465" diameter). The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for international industrial applications.
