S-95893A393 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in various environments
• Enhanced torque transmission and reduced cam-out thanks to the T8 Torx drive, providing secure fastening and minimizing tool slippage
• Efficient thread forming in plastic materials with the tri-lobe shank design, creating strong, vibration-resistant threads without pre-tapping
• Flush, low-profile installation with the standard flat head and 82° countersink angle, ideal for sleek, unobtrusive assemblies
• Full-length threading for maximum grip across the entire 5/8" length, distributing load evenly and preventing pull-out in plastic substrates
• Simplified installation process using a standard No. 37 drill bit, reducing setup time and improving assembly efficiency
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe, sustainable use in global markets

Professional Applications & Engineering Value

These No. 4 zinc-plated steel tapping screws are engineered specifically for plastic applications, addressing common challenges like material cracking and weak thread retention. The thread forming (TRS) design with a tri-lobe shank displaces plastic material to form durable, high-strength threads, eliminating the need for inserts and reducing assembly steps. The T8 Torx drive ensures precise torque control, minimizing strip-out risks in softer plastics, while the flat head with 82° countersink provides a clean, finished appearance. Ideal for electronics enclosures, automotive trim, and consumer products, these screws deliver reliable performance in right-hand threaded assemblies, enhancing productivity and reducing warranty issues.

Specification Summary & Compliance

This product adheres to inch system measurements with a No. 4 screw size, 0.112" thread diameter, and 20 TPI fully threaded design. It meets standard thread forming specifications for TRS tapping screws and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are upheld for industrial use.
