Professional Applications & Engineering Value
This M8 hex head screw is engineered from CU2/CU3 brass, offering exceptional corrosion resistance which is critical in moist, chemical, or marine environments where steel fasteners would fail. The fully threaded metric coarse thread with a 1.25mm pitch and Class 6g tolerance ensures rapid assembly and a secure fit in tapped holes or nuts, reducing installation time and preventing loosening under vibration. With a 50mm length and external hex drive, it provides ample clamping force for machinery, electrical enclosures, and plumbing systems. Its high tensile strength and hardness make it a dependable choice for industrial fastening applications requiring long-term reliability without galvanic corrosion issues when paired with dissimilar metals.
Specification Summary & Compliance
This screw features an M8 x 1.25mm coarse thread with Class 6g thread fit per ISO metric standards, ensuring precise dimensional accuracy. It is manufactured to meet ISO 4017 (identical to DIN 933) for hex head screws. The product is RoHS 3 (2015/863/EU) compliant under exemption 6(c) for lead in copper alloys, confirming its adherence to environmental and safety regulations for industrial use.
