- Coarse M8 x 1.25mm thread with Class 6g fit enables quick assembly and secure fastening in various materials.
- External hex drive allows for high-torque application with standard tools, ensuring tight and consistent clamping force.
- Partial threading provides optimal grip length while minimizing weight and material usage in assembled structures.
Professional Applications & Engineering Value
This M8 hex head screw delivers critical engineering value in heavy-duty applications where vibration resistance and structural reliability are paramount. Manufactured from black-phosphate steel, it combats corrosion in industrial settings, while the Class 10.9 strength rating ensures it withstands high dynamic loads without deformation. The flange design distributes clamping pressure evenly, preventing surface damage and loosening under stress. With its coarse metric thread and partial threading, it offers rapid installation and precise engagement in machinery, automotive assemblies, and construction frameworks, solving common fastening challenges like joint slippage and premature wear.
Specification Summary & Compliance
This screw features an M8 x 1.25mm coarse thread with Class 6g tolerance for consistent fit, a length of 35 mm, and partial threading up to 22 mm. It conforms to ASME B18.2.3.9M specifications and is compliant with RoHS 3 and REACH environmental regulations, ensuring safe and standardized use in global industrial markets.
