Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M5 flat head screws deliver exceptional reliability in machinery assembly, automotive components, and structural frameworks. The zinc-plated alloy steel construction provides critical corrosion resistance, while the Torx T25 drive prevents tool slippage during high-torque applications. With Class 8.8 strength and Rockwell C22 hardness, these metric screws maintain integrity under vibration and dynamic loads. The fully threaded design ensures maximum grip length, and the 90° countersink angle enables seamless surface integration - solving common challenges of fastener failure, installation inefficiency, and aesthetic compromise in precision engineering projects.
Specification Summary & Compliance
This M5 x 40mm flat head screw features precise Class 6h thread fit per metric standards with 0.8mm coarse pitch threading. Manufacturing complies with ISO 14581 specifications for dimensional accuracy and performance. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in restricted substance-sensitive applications. All specifications including right-hand thread direction, 2.7mm head height, and 9.3mm head diameter maintain consistent quality across production batches.
