Professional Applications & Engineering Value
Engineered for industrial assembly and heavy-duty machinery, these M5 hex head screws deliver robust fastening solutions where reliability is critical. The Class 8.8 steel and Rockwell C21 hardness provide excellent resistance to shear and tensile forces, preventing failures in high-vibration settings. With a coarse metric thread and 0.8mm pitch, they offer quick installation and secure holding power in metals, plastics, and composite materials. The black oxide coating adds a layer of corrosion protection, making them suitable for automotive, construction, and equipment manufacturing applications. Fully threaded design ensures maximum grip length, distributing load evenly and reducing the risk of loosening over time.
Specification Summary & Compliance
This M5 x 35mm hex head screw adheres to ISO 4017 (equivalent to DIN 933) dimensional standards with a Class 6g thread fit for precise tolerance. It is manufactured from steel with a tensile strength of 110,000 psi and hardness of Rockwell C21. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets international environmental and safety requirements for industrial use.
