S-95893A505 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
• Excellent torque transfer and reduced cam-out using the Torx Plus IP3 drive, ensuring secure fastening and minimizing tool wear.
• Strong, reliable threads in plastic via the Tri-Lobe shank design, which forms durable mating threads without creating chips.
• Precise, flush installation with a standard 82° flat head profile, providing a clean finish in countersunk applications.
• Full-length threading (42 TPI) ensures maximum grip and holding power across the entire 1/4" length in plastic materials.
• Simplified assembly process with compatibility for a standard No. 55 drill bit, reducing preparation time and errors.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

These TRS thread forming screws are specifically engineered for plastic assembly applications, where traditional fasteners may strip or fail. The Tri-Lobe shank cross-section displaces material during installation, creating strong, load-bearing threads without generating debris that could interfere with sensitive components. Made from 18-8 Stainless Steel, they resist oxidation and corrosion, maintaining integrity in humid or chemically exposed settings. The Torx Plus IP3 drive allows for higher torque application compared to standard drives, reducing the risk of head stripping and improving assembly speed in high-volume production. This combination of thread forming technology and durable material solves common issues like loosening under vibration and material fatigue, making them ideal for electronics enclosures, automotive trim, and consumer products where reliability is critical.

Specification Summary & Compliance

This No. 0 screw size features a 0.06" thread diameter and 1/4" length with fully threaded 42 TPI right-hand threads. The flat head design conforms to an 82° countersink angle for standard flush mounting. Manufactured to precise dimensional tolerances typical for thread forming screws in plastic, it is designed for use with a No. 55 drill bit (0.052" diameter). The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for hazardous substances.
