Professional Applications & Engineering Value
This M16 hex head screw delivers exceptional engineering value through its Class 8.8 steel construction and zinc plated finish, specifically designed to address common industrial challenges. The metric fine threading (1.5mm pitch) provides superior resistance to vibration loosening in machinery, automotive, and structural applications. The partially threaded configuration ensures optimal stress distribution while preventing joint separation. With Rockwell C21 hardness, these hex head screws maintain thread integrity even after repeated installations, reducing replacement costs and downtime in manufacturing environments. The external hex drive facilitates efficient assembly with common tools, making them ideal for high-volume production settings where reliability and speed are critical.
Specification Summary & Compliance
This fastener meets ISO 8765 specifications (equivalent to DIN 960) with Class 6h thread fit tolerance for precise engagement. The 60mm length with 38mm minimum thread length ensures consistent performance across applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards guarantees environmental safety and regulatory adherence for global industrial use. The right-hand thread direction and metric thread system provide universal compatibility with standard components.
