Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Class 12.9 metric socket head cap screw addresses critical challenges in machinery, automotive, and construction sectors. The black-oxide alloy steel construction combats corrosion in humid or chemically aggressive settings, while the coarse M22 x 2.5mm thread ensures rapid assembly and robust clamping force. With a fully threaded design and hex drive, it simplifies maintenance in confined spaces, reducing downtime. Ideal for securing high-load components, this fastener delivers consistent performance where vibration resistance and high tensile strength are paramount, supporting long-term operational reliability.
Specification Summary & Compliance
This socket head cap screw features a 70mm length with Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional tolerances. Manufactured to meet DIN 912/ISO 4762 specifications, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible sourcing. The right-hand coarse thread and fully threaded rod design adhere to international engineering norms for reliability in industrial fastening systems.
