S-90434A205 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for extended service life in various environments
• Superior material displacement through thread forming (TRS) design creates strong, permanent threads in plastic without chipping
• Streamlined installation process with Phillips drive and standard flat head profile requiring only a 1.85mm drill bit
• Maximum holding power achieved through fully threaded M2.5 design with 1.12mm pitch for optimal load distribution
• Secure flush mounting enabled by 90° countersink angle that sits perfectly flush with material surfaces
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, regulated industrial use
• Reliable right-hand threading ensures consistent, predictable fastening performance in plastic assemblies

Professional Applications & Engineering Value

These M2.5 TRS thread forming screws are specifically engineered to address common challenges in plastic assembly applications where traditional fasteners often cause material stress or failure. The zinc-plated steel construction provides essential corrosion protection while the thread forming technology displaces plastic material rather than cutting it, eliminating chips and creating stronger, more reliable threads that resist loosening under vibration. The Phillips flat head design with 90° countersink allows for flush mounting in tight spaces, making these metric tapping screws ideal for electronics enclosures, automotive plastic components, and consumer products where appearance and structural integrity are critical. The combination of fully threaded engagement and precise 1.12mm thread pitch ensures maximum pull-out strength in brittle or soft plastic materials.

Specification Summary & Compliance

This M2.5 x 8mm tapping screw features metric dimensions with fully threaded right-hand orientation and standard thread forming (TRS) profile. Manufactured to precise dimensional standards with 4.7mm head diameter and 1.7mm head height for consistent performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries. The 1.85mm recommended drill bit size and 90° countersink angle provide optimal installation parameters for plastic applications.
