Professional Applications & Engineering Value
These M4 metric screws with zinc-plated steel construction and Torx button head design address critical engineering challenges in industrial assembly. The fully threaded configuration with coarse pitch threading enables rapid installation in metal frameworks, machinery, and equipment where vibration resistance is paramount. The T20 drive system prevents tool slippage during high-torque applications, while the rounded head profile eliminates snagging hazards in confined spaces. With Class 8.8 strength rating and 110,000 psi tensile strength, these fasteners maintain joint integrity under dynamic loads, making them ideal for automotive components, industrial machinery, and electronic enclosures requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
Manufactured to precise ISO 7380 standards with Class 6h thread fit tolerance for consistent dimensional accuracy. The metric coarse thread (M4 x 0.7mm) with right-hand direction follows international threading specifications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial applications. The 25mm length and fully threaded design provide versatile fastening capabilities while maintaining Rockwell C22 hardness for durable performance.
