S-99512A674 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T25 Torx drive that prevents cam-out and reduces tool wear
• Enhanced corrosion resistance through Black-Oxide Steel construction for extended service life in various environments
• Exceptional holding power in plastic materials thanks to the Tri-Lobe shank design that creates secure, vibration-resistant threads
• Reduced installation stress with thread forming technology that eliminates chip formation in plastic assemblies
• Consistent fastening performance with fully threaded design ensuring maximum engagement along the entire 3/4" length
• Simplified installation process using standard No. 15 drill bit (0.18" diameter) for precise hole preparation
• Reliable industrial compliance meeting RoHS 3 and REACH environmental standards for global manufacturing applications

Professional Applications & Engineering Value

These No. 10 TRS thread forming screws are specifically engineered to address common challenges in plastic assembly applications where traditional fasteners often fail. The Tri-Lobe shank cross-section creates a forming action that displaces plastic material rather than cutting it, resulting in zero chip generation and eliminating contamination risks in sensitive assemblies. The Black-Oxide Steel construction provides essential corrosion protection while maintaining the structural integrity needed for demanding industrial environments. With their T25 Torx drive system, these screws deliver maximum torque transfer without stripping, making them ideal for high-volume production lines where consistent fastening performance is critical. The 14 TPI thread pitch and 0.19" thread diameter are optimized for plastic materials, providing superior pull-out resistance while minimizing stress cracking around fastening points.

Specification Summary & Compliance

These thread forming screws feature a No. 10 screw size with 0.19" thread diameter and 14 threads per inch in right-hand orientation. The 3/4" length is fully threaded with a blunt tip design for controlled penetration. Manufactured to precise dimensional standards with a pan head style and standard rounded head profile (0.373" diameter, 0.133" height). The products are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility in industrial applications.
