Professional Applications & Engineering Value

This No. 8 tapping screw delivers exceptional engineering value in plastic assembly applications where material integrity and secure fastening are paramount. The 410 stainless steel construction provides excellent corrosion resistance while the specialized thread cutting technology eliminates the need for pre-tapped holes, significantly reducing assembly time and labor costs. The Phillips pan head design offers a low-profile finish that sits flush against surfaces, making it ideal for electronic enclosures, automotive plastic components, and consumer product assemblies. The fully threaded configuration ensures maximum thread engagement throughout the material thickness, preventing loosening from vibration or thermal cycling. Engineered with precise 18 TPI thread pitch and 0.164" diameter, this screw creates strong, reliable threads in various plastic substrates without causing stress cracking or material failure.

Specification Summary & Compliance

This thread cutting screw features precise dimensional specifications including No. 8 screw size, 3/8" length, 0.164" thread diameter, and 18 threads per inch. The tapping screw type 25/BT follows industry-standard thread forms for plastic applications. Manufacturing compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring hazardous substance restriction compliance for industrial and commercial applications. The screw is designed with standard Class 2A thread tolerances for consistent performance and interchangeability.
