Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with Class 8.8 strength grade and 110,000 psi tensile strength for reliable performance in demanding applications
- Superior wear resistance due to Rockwell C21 hardness, extending service life in high-stress environments
- Quick and secure installation with external hex drive and 17mm head width for efficient torque application
- Optimized thread engagement through M10 coarse threading (1.5mm pitch) ensuring faster assembly and reduced cross-threading risk
- Full-length threading provides consistent clamping force along the entire 100mm length for uniform load distribution
- Environmental compliance assurance with RoHS 3 and REACH regulations for safe usage across regulated industries
- Precision manufacturing to ISO 4017/DIN 933 standards with Class 6g thread fit for consistent quality and interchangeability
Professional Applications & Engineering Value
These M10 hex head screws deliver critical engineering solutions where high-strength fastening is paramount. The Class 8.8 steel construction combined with fully threaded design ensures maximum load distribution across the entire 100mm length, preventing stress concentration in heavy-duty industrial and construction applications. The coarse metric thread (M10x1.5mm) facilitates rapid assembly in structural steel connections, machinery frames, and equipment manufacturing while maintaining Rockwell C21 hardness to withstand vibrational forces and repeated loading cycles. The external hex drive with 17mm head width allows for high-torque installation using standard tools, making these black steel fasteners ideal for demanding environments requiring both mechanical reliability and regulatory compliance.
Specification Summary & Compliance
Manufactured to ISO 4017 / DIN 933 standards with Class 6g thread fit tolerance ensuring precise dimensional accuracy. The metric coarse thread (M10x1.5mm) follows standardized right-hand threading with full-length engagement. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming adherence to international substance restriction requirements for industrial applications.
