S-90380A375 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in various environments.
• Excellent thread-forming capability with TRS design creates strong, reliable threads in plastic materials without pre-tapping.
• Secure and efficient installation through Phillips No. 2 drive system that prevents cam-out and ensures proper torque transmission.
• Optimized plastic fastening performance with blunt tip and fully threaded design that minimizes material stress and cracking.
• Wide compatibility with standard 3mm pilot holes for quick installation across various plastic applications.
• Enhanced holding power through precise 1.79mm thread pitch that maximizes engagement and pull-out resistance.
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing practices.

Professional Applications & Engineering Value

These M4 x 8mm zinc-plated steel tapping screws are specifically engineered for plastic fastening applications where material integrity is paramount. The TRS thread forming technology creates permanent, high-strength threads in plastic substrates without generating chips or debris that could compromise electronic components or mechanical assemblies. The Phillips drive system ensures consistent installation torque, while the standard pan head design provides a low-profile finish with excellent bearing surface. These metric tapping screws solve critical challenges in plastic assembly by eliminating the need for separate tapping operations, reducing installation time by up to 50% compared to traditional fastening methods. The fully threaded configuration with precise 1.79mm pitch distributes clamping force evenly, preventing stress concentration points that lead to plastic cracking or failure in vibration-prone environments.

Specification Summary & Compliance

This M4 x 8mm tapping screw features metric threading with standard pitch tolerance, TRS thread forming design compliant with industry standards for plastic fastening applications. The screw maintains dimensional accuracy with 7mm head diameter and 2.8mm head height for consistent performance. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring product safety and regulatory adherence for global industrial applications.
