Professional Applications & Engineering Value
This M12 hex head screw delivers exceptional engineering value through its Class 8.8 steel construction and zinc plating surface treatment. The combination of fine metric threading (1.5mm pitch) and partial threading design addresses common industrial challenges by providing superior vibration resistance while minimizing stress risers in assembled components. The external hex drive facilitates high-torque installation in confined spaces, making these industrial screws ideal for machinery assembly, structural frameworks, and heavy equipment manufacturing. With Rockwell C21 hardness ensuring thread durability, these fasteners maintain clamping force integrity in dynamic loading conditions, reducing maintenance frequency and downtime in production environments.
Specification Summary & Compliance
This metric screw features precise Class 6h thread fit tolerance and complies with ISO 8765 specifications where identified as DIN 960. The fastener meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) certification for chemical safety. Manufacturing follows international standards for right-hand thread configuration and dimensional accuracy, ensuring interchangeability and reliable performance in global industrial applications.
