S-90434A146 Length 14 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
• Efficient thread forming design (TRS type) creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and costs.
• Secure and stable fastening with a fully threaded M3 x 14mm metric size and standard flat head profile, providing consistent holding power and flush installation.
• Easy installation and reduced tool wear thanks to the Phillips No. 1 drive, allowing for quick driving with common tools and minimizing slippage.
• Optimized for plastic applications with a blunt tip and 90° countersink angle, preventing material cracking and ensuring a clean, professional finish.
• Compatibility with standard 2.25mm drill bits simplifies hole preparation, streamlining the assembly process for high-volume production.
• Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use in global industrial supply chains.

Professional Applications & Engineering Value

This M3 TRS thread forming screw is engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The zinc-plated steel material offers excellent durability and resistance to environmental factors, while the thread forming (tapping) method displaces plastic to create robust, load-bearing threads without chips, reducing the risk of loosening. Ideal for applications in electronics, automotive components, and consumer goods, this Phillips flat head screw ensures reliable performance in plastic materials, with its fully threaded design and precise 90° countersink angle enabling flush mounting and enhanced structural integrity. By minimizing assembly steps and improving joint strength, it supports efficient, high-quality manufacturing processes.

Specification Summary & Compliance

This screw adheres to standard metric (M3) dimensions with a length of 14mm, fully threaded design, and right-hand thread direction for consistent fastening. It is manufactured to precise tolerances suitable for thread forming applications in plastics, with compatibility for a 2.25mm drill bit and 90° countersink angle. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
