Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these Class 12.9 metric steel hex head screws deliver exceptional performance in machinery assembly, structural steel connections, and equipment manufacturing. The fully threaded M14x2mm coarse pitch design provides superior resistance to loosening under vibration, while the external hex drive enables high-torque installation without stripping. The high-strength steel construction with precise Class 6g thread fit ensures reliable performance in critical joints subject to dynamic loads and extreme conditions. These ISO 4017 DIN 933 compliant fasteners solve common engineering challenges by offering predictable failure points and consistent mechanical properties across production batches.

Specification Summary & Compliance

Manufactured to ISO 4017 and DIN 933 standards with Class 6g thread tolerance for precision fit. The M14x2mm coarse thread configuration follows metric threading specifications with right-hand thread direction. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence. The Class 12.9 strength rating guarantees minimum tensile strength of 170,000 psi with Rockwell C39 hardness, meeting international requirements for high-strength fasteners in industrial applications.
