Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Class 10.9 steel hex head screws deliver critical performance where structural integrity matters most. The M20 coarse thread configuration with 2.5mm pitch provides rapid installation while maintaining vibration resistance in machinery, construction, and equipment manufacturing. The blue-dyed zinc plating creates a protective barrier against corrosion, significantly extending service life in challenging environments. With partial threading design, these metric hex bolts offer both precise clamping force and unthreaded shank strength, making them ideal for structural connections, heavy machinery assembly, and infrastructure projects requiring high tensile strength and reliable fastening solutions.
Specification Summary & Compliance
Manufactured to ISO 4014 specifications (equivalent to DIN 931) with Class 6g thread fit tolerance ensuring precise engagement. The 80mm length provides 46mm minimum thread length for secure fastening depth. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, these screws meet international standards for industrial use. The Class 10.9 strength rating and Rockwell C32 hardness guarantee consistent performance under high-stress conditions.
