S-92400A280 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic with TRS thread forming design that creates strong, permanent threads without chips
• Enhanced corrosion resistance through zinc-plated steel construction for extended service life in various environments
• High-torque installation capability with external hex drive head that prevents stripping during assembly
• Excellent resistance to back-out thanks to the tri-lobe shank design that provides secure locking in plastic materials
• Full thread engagement with completely threaded shank for maximum grip strength across the entire fastener length
• Precision fit with No. 21 drill bit compatibility ensuring proper hole size and optimal thread formation
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, regulated use

Professional Applications & Engineering Value

These No. 10 TRS tapping screws deliver exceptional performance in plastic assembly applications where traditional fasteners often fail. The thread forming technology eliminates chip formation during installation, preventing contamination in sensitive electronic enclosures and automotive plastic components. The tri-lobe shank cross-section creates compressive forces that generate superior resistance to vibration loosening, while the zinc-plated steel construction provides reliable corrosion protection in industrial environments. With 14 threads per inch and 0.19" thread diameter, these fasteners offer precise engagement in thermoplastic and thermoset materials, making them ideal for plastic fabrication, electronic housing assembly, and automotive interior applications where reliable, long-term fastening is critical.

Specification Summary & Compliance

This No. 10 x 3/8" TRS tapping screw features inch system measurements with fully threaded right-hand orientation and blunt tip design. The fastener demonstrates precision manufacturing with 0.312" hex head width and 0.414" flange diameter for consistent installation. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory compliance for industrial use. Designed specifically for use with No. 21 drill bit (0.159" diameter) to achieve optimal thread formation in plastic materials.
