- Superior corrosion resistance from the black-oxide finish prolongs service life in harsh industrial environments, minimizing maintenance needs.
- Precise Class 3A thread fit provides tight tolerances for secure fastening, enhancing assembly integrity and vibration resistance.
- Partially threaded design allows for controlled clamping force and easier alignment in complex machinery setups.
- High hardness (Rockwell C37) offers excellent wear resistance, maintaining thread integrity over repeated use.
- 3/8" hex drive compatibility enables efficient installation with standard tools, speeding up assembly processes.
- Compliance with ASTM A574, RoHS 3, and REACH ensures adherence to industry standards for safety and environmental responsibility.
Professional Applications & Engineering Value
This 7/16"-14 UNC socket head cap screw is engineered from black-oxide alloy steel to address critical challenges in heavy-duty industrial settings. Its coarse thread and Class 3A fit provide superior grip in high-vibration environments, such as machinery, automotive assemblies, and construction equipment, preventing loosening under dynamic loads. The partially threaded rod type allows for precise clamping without over-tightening, reducing stress concentrations. With a tensile strength of 170,000 psi and corrosion-resistant coating, it delivers long-term reliability in demanding applications, minimizing downtime and replacement costs for engineers and procurement specialists.
Specification Summary & Compliance
This socket head cap screw features a 7/16"-14 UNC coarse thread with Class 3A thread fit for high precision, and a partially threaded design with a minimum thread length of 1 3/8". It meets ASTM A574 specifications for high-strength fasteners and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
