Professional Applications & Engineering Value
These M6 hex head screws deliver critical engineering advantages in heavy-duty industrial applications where vibration resistance and structural integrity are paramount. The Class 8.8 steel construction provides optimal strength-to-weight ratio, while the fully threaded design ensures maximum clamping force distribution across the entire 65 mm length. The coarse metric thread with 1 mm pitch enables rapid assembly in structural steel, machinery, and equipment manufacturing, significantly reducing installation time compared to fine-thread alternatives. The external hex drive accommodates high torque requirements, making these black steel screws ideal for applications requiring frequent maintenance or disassembly without compromising fastener integrity.
Specification Summary & Compliance
Manufactured to ISO 4017/DIN 933 standards with Class 6g thread tolerance ensuring precise fit in metric applications. The M6 x 1 mm coarse thread configuration maintains dimensional accuracy per international metric specifications. Compliance verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and material restrictions adherence. Class 8.8 strength rating guarantees consistent mechanical properties across production batches for reliable performance in critical assemblies.
