Key Features & Benefits at a Glance
- Exceptional load-bearing capability with Class 10.9 strength grade, ensuring reliable performance under high-stress conditions
- Superior corrosion resistance and durability from black steel construction, extending service life in harsh industrial environments
- Easy installation and removal with external hex drive and 13mm head width, allowing for standard tool compatibility
- Optimized thread engagement through M8 coarse 1.25mm pitch, reducing cross-threading risks and speeding assembly
- Precise partial threading (22mm min thread length on 130mm shank) provides secure fastening while minimizing weight
- Guaranteed dimensional accuracy with Class 6g thread fit, ensuring consistent performance across applications
- Full regulatory compliance meeting DIN 931, RoHS 3, and REACH standards for global market acceptance
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M8 hex head screws deliver critical reliability where failure isn't an option. The Class 10.9 steel construction provides exceptional tensile strength (150,000 psi) and Rockwell C32 hardness to withstand extreme vibrations and dynamic loads in machinery assembly, structural steel connections, and automotive frameworks. The coarse metric thread with 1.25mm pitch ensures rapid installation in both soft and hard materials while resisting loosening. Partial threading concentrates strength where needed most, making these DIN 931 compliant fasteners ideal for applications requiring precise clamp load distribution without unnecessary thread engagement.
Specification Summary & Compliance
This M8 x 1.25 hex head screw maintains Class 6g thread tolerance for precision fit and meets DIN 931 manufacturing specifications. The fastener demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. With 130mm length and 22mm minimum thread length, it provides consistent performance across industrial applications requiring metric coarse thread fasteners with external hex drive configuration.
