Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance under extreme loads, minimizing failure risks in critical assemblies.
- Superior corrosion resistance from the black-oxide finish prolongs service life in harsh industrial environments, reducing maintenance needs.
- Precise hex socket drive (14mm) allows for high-torque installation with standard tools, enhancing assembly efficiency and reducing slippage.
- Class 12.9 strength rating guarantees consistent durability and fatigue resistance for heavy-duty applications.
- Partially threaded design with M16 coarse pitch (2mm) provides optimal grip and ease of alignment in varied material thicknesses.
- Compliance with DIN 912/ISO 4762 standards ensures dimensional accuracy and interchangeability, streamlining global procurement.
- RoHS 3 and REACH environmental compliance supports sustainable operations by meeting strict regulatory requirements.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this M16 socket head cap screw combines black-oxide alloy steel and a Class 12.9 strength rating to address common challenges like vibration loosening and material fatigue. The coarse thread (2mm pitch) and partially threaded rod design facilitate quick installation in heavy machinery, automotive frames, and structural assemblies, where high clamp load and alignment precision are critical. Its hex drive enables secure tightening in confined spaces, reducing assembly time while maintaining 170,000 psi tensile strength for long-term reliability under dynamic stresses.
Specification Summary & Compliance
This fastener adheres to ISO 4762 / DIN 912 specifications, with a Class 5g6g thread fit for precise dimensional tolerance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety. The Rockwell C37 hardness and 44mm minimum thread length further validate its consistency in high-stress applications.
