Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish prolongs service life in harsh industrial environments, minimizing maintenance needs.
- Precise Class 3A thread fit guarantees secure, vibration-resistant connections for enhanced assembly integrity.
- High hardness (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Fully threaded design allows for maximum adjustability and uniform clamping force along the entire length.
- Coarse UNC thread enables quick installation and reduced cross-threading risk, improving assembly efficiency.
- 3/8" hex drive compatibility offers easy installation with standard tools, streamlining maintenance and repair processes.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this black-oxide alloy steel socket head cap screw delivers critical reliability where failure is not an option. The combination of 170,000 psi tensile strength and Rockwell C37 hardness makes it ideal for heavy machinery, automotive assemblies, and construction equipment subjected to extreme loads and vibrations. The fully threaded UNC coarse thread design ensures rapid installation in time-sensitive production environments while maintaining Class 3A precision for vibration-resistant connections. The black-oxide surface treatment provides essential corrosion protection in humid or chemically exposed applications, extending service intervals and reducing lifecycle costs. These socket head cap screws are particularly valuable in confined spaces where the hex drive allows for precise torque application without compromising structural integrity.
Specification Summary & Compliance
This fastener maintains Class 3A thread fit per UNC standards with 7/16"-14 coarse threading and right-hand direction. Manufacturing complies with ASTM A574 specification for high-strength socket head cap screws. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets.
