S-92727A130 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel and Black-Oxide coating, ideal for harsh environments and extending service life.
• Enhanced torque transmission and reduced cam-out thanks to the Torx T10 drive, ensuring secure fastening and minimizing tool slippage.
• Reliable thread forming in plastics with the Tri-Lobe shank design, creating strong, vibration-resistant threads without pre-tapping.
• Optimized for plastic assembly with a blunt tip and right-hand threading, preventing material cracking and ensuring smooth installation.
• Precise fit and compatibility with a No. 37 drill bit (0.104" diameter), guaranteeing accurate hole sizing and consistent performance.
• Full threading for maximum grip across the entire 3/8" length, providing uniform clamping force in various material thicknesses.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in industrial applications.

Professional Applications & Engineering Value

This No. 4-20 TRS tapping screw is engineered to address common challenges in plastic assembly, such as strip-out and material stress. The thread forming Tri-Lobe shank displaces plastic material to create durable, high-retention threads, eliminating the need for separate inserts and reducing assembly time. Made from 18-8 stainless steel with a Black-Oxide finish, it resists rust and corrosion in humid or chemical-exposed settings. The Torx T10 drive offers superior torque control compared to Phillips or slotted drives, minimizing operator fatigue and ensuring consistent clamp load in automated or manual industrial fastener applications, from electronics enclosures to automotive components.

Specification Summary & Compliance

This screw features a No. 4-20 thread with a 3/8" length, fully threaded design, and blunt tip for use in plastics. It complies with standard inch measurements and is designed for use with a No. 37 drill bit (0.104" diameter). The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial supply chains.
