Key Features & Benefits at a Glance
- Enhanced corrosion resistance with black-oxide coating, extending service life in harsh industrial environments
- Superior torque transmission from the 12-point external drive design, preventing tool slippage during high-tension applications
- Exceptional mechanical strength with 180,000 psi tensile rating and Rockwell C38 hardness for heavy-duty load requirements
- Integrated flange design eliminates separate washers, providing wider bearing surface and simplified assembly
- Precision Class 4h thread fit ensures consistent engagement and reliable fastening in metric assemblies
- Full threading along 16mm length offers maximum adjustment flexibility and uniform stress distribution
- Coarse 1.25mm pitch enables rapid installation and reduced cross-threading risk in production environments
Professional Applications & Engineering Value
Engineered for demanding industrial applications, this M8 12-point screw combines black-oxide alloy steel construction with precision metric coarse threading to address critical fastening challenges. The flanged design provides distributed clamping force that prevents surface damage while eliminating loose washers in assembly lines. With Class 4h thread fit maintaining tight tolerances, these fully threaded screws deliver vibration resistance in machinery, automotive subsystems, and heavy equipment where 180,000 psi tensile strength prevents joint failure under dynamic loads. The external 12-point drive accommodates standard industrial tools for high-torque installation without stripping concerns.
Specification Summary & Compliance
Manufactured to metric standards with M8 x 1.25mm coarse threads and Class 4h thread fit precision. The black-oxide surface treatment provides corrosion protection while maintaining dimensional stability. Meets industry standards for alloy steel fasteners with verified Rockwell C38 hardness and 180,000 psi tensile strength. Compliant with RoHS and REACH environmental directives for industrial use.
