S-92295A109 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black Zinc-Plated Steel coating, extending service life in demanding industrial environments
• Exceptional holding power in plastic materials through advanced Tri-Lobe shank design that displaces material without creating chips
• Reduced installation torque requirements with thread forming technology that creates stronger, more reliable threads in plastic substrates
• Optimized drive efficiency with Phillips No. 1 drive style providing secure tool engagement and reduced cam-out risk
• Precision dimensional control with 20 threads per inch ensuring consistent performance and reliable fastening in plastic applications
• Enhanced environmental compliance meeting RoHS 3 and REACH standards for global manufacturing requirements
• Streamlined installation process with compatible No. 37 drill bit (0.104" diameter) for precise hole preparation

Professional Applications & Engineering Value

These TRS thread forming screws deliver exceptional engineering value in plastic assembly applications where traditional fastening methods often fail. The Tri-Lobe shank cross-section and thread forming technology work synergistically to compress plastic material rather than cutting through it, eliminating problematic chips while creating zero-clearance threads that significantly enhance pull-out resistance. The Black Zinc-Plated Steel construction provides critical corrosion protection in environments where moisture or chemicals may be present, while the fully threaded design ensures maximum engagement depth throughout the 3/4" length. This combination addresses common industrial pain points including thread stripping, material cracking, and premature fastener failure in thermoplastics and other polymer substrates used across automotive, electronics, and consumer goods manufacturing.

Specification Summary & Compliance

This No. 4 x 3/4" TRS tapping screw features precision inch measurements with a thread diameter of 0.112" and 20 threads per inch for consistent fastening performance. Manufactured to TRS (Thread Rolling Screw) standards with right-hand threading and blunt tip configuration optimized for plastic materials. The screw demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring strict material restrictions.
