S-95893A382 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention with Tri-Lobe shank design that creates secure, vibration-resistant threads in plastic materials
• Maximum torque transfer through T27 Torx drive system, preventing cam-out and tool slippage during installation
• Enhanced corrosion resistance with zinc-plated steel construction for extended service life in industrial environments
• Efficient thread forming technology eliminates chips and debris, reducing assembly time and cleanup requirements
• Flush mounting capability with 82° countersink angle and flat head design for smooth surface finishes
• Full-length threading provides consistent holding power along the entire 3/4" length for reliable fastening
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated applications

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are specifically engineered to address common challenges in plastic fastening applications. The thread forming design with Tri-Lobe shank cross-section creates strong, permanent threads in plastic substrates without generating chips that could compromise electronic components or contaminate clean environments. The T27 Torx drive system ensures maximum torque transmission, reducing installation time and preventing fastener damage that often occurs with Phillips or slotted drives. The combination of fully threaded construction and 82° countersink angle provides reliable pull-out resistance while maintaining flush surface profiles critical for aesthetic applications in consumer products, automotive components, and electrical enclosures where plastic-to-plastic or plastic-to-metal joining is required.

Specification Summary & Compliance

This 1/4"-10 TRS tapping screw features precision right-hand threads with Class 2A thread tolerances and requires a 0.234" (A drill size) pilot hole for optimal performance. The flat head design with standard profile and blunt tip facilitates easy starting in plastic materials. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for industrial applications requiring chemical substance restrictions.
