S-90485A466 Length 14 mm 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 in industrial settings.
• Efficient thread forming design (TRS type) creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and labor costs.
• Secure and flush installation thanks to the flat head with 90° countersink angle, providing a smooth surface finish and preventing snagging in plastic applications.
• Easy drive engagement with Phillips No. 2 drive, ensuring quick installation and reducing the risk of cam-out for consistent fastening performance.
• Full threading and blunt tip design offers maximum grip and prevents material splitting, enhancing fastener integrity in delicate plastic components.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries and global market acceptance.
• Precise M4 x 1.79mm metric sizing delivers accurate fit and reliable performance, compatible with standard No. 30 drill bits for streamlined workflows.

Professional Applications & Engineering Value

These M4 tapping screws are engineered to address common challenges in plastic fastening, where material integrity and corrosion resistance are critical. The 18-8 stainless steel composition provides excellent durability against moisture and chemicals, reducing maintenance needs in industrial applications. The TRS thread forming design eliminates the need for separate tapping operations, minimizing assembly errors and enhancing production efficiency. With a Phillips flat head and 90° countersink, these screws ensure a secure, flush fit that prevents protrusion in enclosures or consumer products. Ideal for electronics, automotive panels, and appliance manufacturing, they offer a reliable fastening solution that withstands vibration and environmental stressors, backed by RoHS and REACH compliance for global supply chain integration.

Specification Summary & Compliance

This M4 x 1.79mm metric Phillips flat head tapping screw adheres to standard thread forming (TRS) specifications with a right-hand thread direction and fully threaded shank. It is designed for use with a No. 30 drill bit (0.1285" diameter) and features a 90° countersink angle for precise installation. The screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial and manufacturing applications.
