- Optimized torque transfer with Phillips No. 1 drive that minimizes cam-out and ensures secure fastening
- Reduced material stress thanks to blunt tip design that displaces plastic evenly during installation
- Simplified installation process with fully threaded shank and standard 1.85mm drill bit size for precise fit
- Reliable industrial compliance meeting RoHS 3 and REACH environmental standards for safe usage
- Secure fastening profile with pan head design providing excellent bearing surface and 4.4mm head diameter
Professional Applications & Engineering Value
These M2.5 thread forming screws deliver exceptional engineering value in plastic assembly applications where traditional fastening methods often fail. The zinc-plated steel construction combined with TRS thread forming technology eliminates common issues like material cracking and strip-out by displacing plastic rather than cutting it. The fully threaded design with 1.12mm pitch ensures maximum thread engagement while the Phillips No. 1 drive provides reliable torque transmission during installation. This combination makes these metric tapping screws ideal for electronics enclosures, automotive plastic components, and consumer products where vibration resistance and long-term reliability are critical.
Specification Summary & Compliance
This M2.5 x 8mm tapping screw features precision metric threading with fully threaded shank and standard thread form for consistent performance. The screw maintains dimensional accuracy with 4.4mm head diameter and 1.8mm head height pan head profile. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage in industrial applications. Recommended drill bit size of 1.85mm provides optimal clearance for thread forming installation in plastic materials.
