Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
- Excellent holding power in plastic materials thanks to the Tri-Lobe shank design that prevents loosening and back-out
- Efficient thread forming action creates strong, permanent threads in plastic without pre-tapped holes
- Reliable Phillips drive system with No. 2 size provides secure installation and prevents cam-out during tightening
- Optimized blunt tip design ensures proper alignment and reduces stress cracking in plastic substrates
- Full 7/8" threading delivers maximum engagement and pull-out resistance in plastic assemblies
- Environmental compliance assurance with RoHS 3 and REACH standards for sustainable manufacturing
Professional Applications & Engineering Value
This No. 10 TRS thread forming screw is specifically engineered for plastic fastening applications where reliability and material compatibility are critical. The 18-8 stainless steel construction provides exceptional corrosion resistance, while the Tri-Lobe shank cross-section creates a secure interference fit that eliminates the need for additional locking components. The thread forming design displaces plastic material rather than cutting it, resulting in stronger threads with reduced stress concentration. The Phillips pan head offers a low-profile finish with excellent drive transfer, making these plastic screws ideal for electronics enclosures, automotive trim, consumer products, and industrial equipment where vibration resistance and long-term performance are essential.
Specification Summary & Compliance
This tapping screw features a No. 10 size with 7/8" length, 0.19" thread diameter, and 14 threads per inch. The TRS (Thread Rolling Screw) design utilizes a Tri-Lobe shank cross-section for optimal performance in plastic materials. Manufactured to precise dimensional standards with right-hand threading and fully threaded shank. Compatible with No. 21 drill bit (0.159" diameter) for proper installation. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
