  • Enhanced torque transmission and reduced cam-out with Torx Plus IP10 drive, ensuring secure fastening and tool longevity
  • Reliable thread formation in plastics through the Tri-Lobe shank design, creating strong, permanent threads without pre-tapping
  • Flush, professional finish achieved with the standard flat head and 82° countersink angle for seamless integration into assemblies
  • Full-length threading provides maximum grip and consistent holding power along the entire screw length
  • Precision dimensional accuracy with No. 6 diameter and 3/4" length ensures perfect fit and repeatability in plastic applications
  • Compliance with global environmental standards including RoHS 3 and REACH for safe, sustainable manufacturing

Professional Applications & Engineering Value

This No. 6 x 3/4" TRS thread forming screw delivers exceptional engineering value in plastic assembly applications where material integrity and fastening reliability are critical. The 18-8 stainless steel construction provides excellent corrosion resistance, while the Tri-Lobe shank design displaces plastic material during installation to form permanent, high-strength threads without creating internal stresses that could lead to cracking. The Torx Plus IP10 drive system enables higher torque application with minimal cam-out, reducing assembly time and preventing fastener damage. The flat head with 82° countersink angle ensures a flush finish that maintains aerodynamic and aesthetic surfaces in consumer electronics, automotive components, and industrial equipment enclosures.

Specification Summary & Compliance

This thread forming screw features precision No. 6 thread diameter (0.138") with 19 TPI right-hand threading and full-length thread coverage. The flat head design measures 0.262" in diameter with 0.083" height, compatible with standard 82° countersink preparations. Manufactured to exacting standards for plastic fastening applications with recommended 1/8" drill bit size. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental regulations for industrial components.
