Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this M8 metric screw combines Class 10.9 high-strength alloy steel with blue-dyed zinc plating to address critical challenges like vibration-induced loosening and environmental corrosion. The fully threaded coarse pitch design (M8 x 1.25mm) ensures rapid installation and superior grip in metals, plastics, and assembled structures, while the rounded button head with 5mm hex drive allows for flush mounting and high-torque application without stripping. Ideal for machinery, automotive assemblies, and construction equipment where precision threading and long-term reliability are paramount, this fastener minimizes maintenance downtime and enhances structural integrity under extreme operational stresses.
Specification Summary & Compliance
This M8 x 1.25mm coarse pitch screw adheres to ISO 7380 standards with Class 6g thread fit for precise dimensional accuracy. Manufactured from alloy steel with a tensile strength of 140,000 psi and Rockwell C32 hardness, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory acceptance in global markets.
