S-95893A212 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP8 drive that minimizes cam-out and tool slippage during installation
• Exceptional thread retention in plastic materials through Tri-Lobe shank design that creates permanent, vibration-resistant threads
• Corrosion-resistant protection with zinc plating that extends service life in demanding industrial environments
• Streamlined installation process with standard 82° flat head profile that sits flush with surfaces and No. 44 drill bit compatibility
• Reliable thread forming performance using TRS technology that eliminates chips and creates strong threads without pre-tapping
• Enhanced driving efficiency with fully threaded blunt tip design that ensures consistent engagement in plastic substrates
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

This No. 4-20 x 1/4" zinc-plated steel TRS tapping screw delivers exceptional engineering value in plastic assembly applications where vibration resistance and thread integrity are critical. The thread forming technology with Tri-Lobe shank cross-section displaces plastic material to create permanent, high-strength threads that won't loosen under dynamic loads. The Torx Plus IP8 drive system provides superior torque transmission compared to conventional drives, eliminating cam-out issues that can damage screw heads and compromise assembly quality. Specifically designed for plastic materials, this fastener solves common challenges in electronics enclosures, automotive plastic components, and consumer products where reliable fastening in brittle or soft plastics is essential. The combination of right-hand threading and blunt tip design ensures controlled penetration without material cracking or stress concentration.

Specification Summary & Compliance

This No. 4-20 x 1/4" TRS tapping screw features precise inch system dimensions with 20 threads per inch and standard Class 2A thread tolerances. The fastener incorporates thread forming (TRS) technology with Tri-Lobe shank cross-section, engineered for use in plastic substrates with recommended No. 44 drill bit (0.086" diameter) and standard 82° countersink angle. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory compliance for industrial applications worldwide.
