Professional Applications & Engineering Value
Engineered for demanding environments, this Grade 8 steel hex head screw delivers robust performance in heavy machinery, construction, and automotive assemblies. The fully threaded UNC coarse thread design provides superior grip and load distribution, preventing loosening under dynamic stresses. With a zinc yellow-chromate plating, it resists corrosion from moisture, chemicals, and outdoor exposure, making it ideal for infrastructure and equipment subjected to harsh conditions. The external hex drive ensures straightforward installation with common wrenches, reducing labor time while maintaining high tensile strength and Rockwell C33 hardness to withstand extreme forces without deformation.
Specification Summary & Compliance
This fastener adheres to Class 2A thread fit for precise dimensional accuracy and smooth assembly, meeting ASME B18.2.1 and SAE J429 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The 5/8"-11 UNC coarse thread and 3" length provide consistent performance in standardized applications.
