Professional Applications & Engineering Value

Engineered for industrial fastening where durability and precision are critical, these M5 hex head screws in CU2/CU3 brass address common challenges like corrosion in electrical enclosures, plumbing systems, and marine equipment. The coarse metric thread with 0.8mm pitch and Class 6g tolerance ensures quick, reliable installations in soft materials or pre-tapped holes, minimizing assembly time and reducing failure risks. With fully threaded construction and external hex drive, they provide uniform stress distribution and easy access in confined spaces, making them ideal for high-vibration environments and machinery requiring frequent disassembly. Their right-hand thread design aligns with standard practices, facilitating seamless integration into existing metric fastener systems while offering long-term performance in automotive, HVAC, and electronic assemblies.

Specification Summary & Compliance

This product adheres to ISO 4017 and DIN 933 specifications, with thread fit Class 6g ensuring precise dimensional accuracy for metric coarse threads (M5 x 0.8mm). It meets RoHS 3 (2015/863/EU) compliance under exemption 6(c) for lead in copper alloys, supporting use in regulated industries. The screw features a fully threaded 25mm length, external hex drive with 8mm head width, and right-hand thread direction, manufactured to consistent hardness (Rockwell B55) and tensile strength (50,000 psi) standards for reliable performance.
