Professional Applications & Engineering Value

This M5 Torx button head screw is engineered to address common industrial challenges such as vibration loosening, corrosion, and the need for high-strength, low-profile fastening. The zinc-plated steel construction provides a protective barrier against rust and chemical exposure, making it ideal for machinery, automotive assemblies, and electronic enclosures. The Class 8.8 strength grade ensures it can withstand significant mechanical stress, while the T25 Torx drive offers superior torque transfer compared to Phillips or slotted drives, reducing cam-out and damage during installation. The fully threaded design and coarse 0.8 mm pitch enable rapid installation and secure clamping in a variety of materials, from metal to plastic, streamlining production and maintenance processes.

Specification Summary & Compliance

This fastener features a Class 6h thread fit and M5 x 0.8 mm coarse thread with right-hand direction, manufactured to ISO 7380 dimensional standards. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances. The screw is fully threaded and meets the mechanical properties for Class 8.8, including a tensile strength of 110,000 psi and Rockwell C22 hardness, confirming its reliability for industrial use.
