Professional Applications & Engineering Value
This high-strength alloy steel set screw delivers critical performance in demanding industrial applications where vibration resistance and permanent positioning are essential. The cup tip design provides concentrated contact pressure that bites into shaft materials, preventing rotational slippage in power transmission components, gear assemblies, and precision machinery. Engineered with Class 5g6g thread fit and coarse M5x0.8mm metric threading, it offers superior resistance to loosening while accommodating minor misalignments. The Rockwell C45 hardness ensures the hex headless set screw maintains its structural integrity under repeated stress cycles, making it ideal for permanent fastening in automotive, manufacturing, and heavy equipment applications where reliability cannot be compromised.
Specification Summary & Compliance
This metric set screw features precise M5x0.8mm coarse threading with Class 5g6g tolerance according to ISO metric thread standards. The 16mm length and headless design conform to DIN 916 ISO 4029 specifications for dimensional accuracy and performance requirements. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance across international markets. The right-hand thread direction and 2.5mm hex drive provide standardized installation compatibility with common industrial tools.
