S-90434A147 Length 14 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials through TRS thread forming design that displaces material without cutting, reducing stress cracking.
• Enhanced corrosion resistance with zinc-plated steel construction, ensuring longevity in various industrial environments.
• Efficient installation and flush finishing with a standard 90° countersink flat head and Phillips No. 2 drive for secure, tamper-resistant assemblies.
• Full thread engagement for maximum grip across the entire 14mm length, providing reliable fastening in plastic components.
• Simplified drilling preparation with compatibility for standard 2.6mm drill bits, reducing setup time and errors.
• Compliance with environmental regulations, meeting RoHS 3 and REACH standards for safe, sustainable use in global markets.
• Durable and reusable fastening solution due to the robust thread forming method and high-strength steel material.

Professional Applications & Engineering Value

These M3.5 x 14mm zinc-plated steel TRS thread forming screws are engineered to address common challenges in plastic assembly, such as material cracking and weak thread retention. The thread forming technique creates strong, permanent threads by compressing plastic fibers, rather than cutting them, which minimizes the risk of failure in applications like electronics enclosures, automotive trim, and consumer goods. The flat head with a 90° countersink ensures a smooth, flush surface, while the Phillips drive allows for quick installation with standard tools. Made from zinc-plated steel, these screws offer excellent resistance to corrosion, making them ideal for both indoor and outdoor plastic fastening needs, and their full threading provides uniform stress distribution for enhanced durability in dynamic environments.

Specification Summary & Compliance

This product adheres to standard metric (M3.5) dimensions with a length of 14mm, fully threaded design, and a blunt tip for effective thread forming in plastics. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance. The screw is designed for use with a 2.6mm drill bit and features a 90° countersink angle, providing precise fit and ease of installation in various plastic materials.
