Key Features & Benefits at a Glance
- Exceptional durability with Class 12.9 strength grade, providing reliable performance under extreme mechanical stress.
- Superior load-bearing capacity due to 170,000 PSI tensile strength, ideal for heavy-duty industrial applications.
- Enhanced wear resistance from Rockwell C39 hardness, extending service life in high-friction environments.
- Easy installation and removal with external hex drive and standard 22mm head width, compatible with common tools.
- Secure fastening in coarse materials thanks to M14 x 2mm coarse pitch threading, reducing cross-threading risks.
- Full-length threading ensures maximum grip and uniform stress distribution along the entire 50mm length.
- Global compliance assurance meeting ISO 4017, RoHS 3, and REACH standards for safety and environmental responsibility.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this M14 hex head screw delivers critical reliability in machinery assembly, structural frameworks, and automotive systems. The Class 12.9 steel construction and fully threaded metric design prevent joint failure under vibration and dynamic loads, while the coarse pitch thread facilitates quick installation in brittle or soft materials. With a Rockwell C39 hardness rating, it resists deformation and maintains clamp force in high-temperature or corrosive environments, reducing maintenance downtime. Ideal for OEMs and MRO operations requiring ISO 4017 compliant fasteners that meet rigorous performance and regulatory standards.
Specification Summary & Compliance
This screw adheres to ISO 4017 specifications (equivalent to DIN 933) with Class 6g thread fit tolerance for precise engagement. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted hazardous substances are used. The manufacturing process follows standardized metric dimensions, including M14 thread size, 2mm pitch, and 50mm length, guaranteeing interchangeability and consistent quality across industrial applications.
