Professional Applications & Engineering Value
This cadmium-plated alloy steel socket head cap screw delivers critical performance where vibration resistance and structural integrity are paramount. The Class 3A UNRC coarse thread configuration prevents loosening in high-stress environments while enabling rapid assembly in production lines. Engineered with 160,000 psi tensile strength and Rockwell C39 hardness, this fastener withstands extreme mechanical loads in heavy machinery, aerospace frameworks, and precision equipment. The fully threaded design provides maximum engagement in tapped holes, while the cadmium plating offers essential corrosion protection for outdoor or chemically exposed applications. These industrial fasteners are specifically designed to maintain clamp force integrity where standard fasteners would fail.
Specification Summary & Compliance
This 1/4"-20 x 3/8" socket head cap screw features precision Class 3A thread fit with UNRC coarse threads in right-hand direction. Manufactured to meet MS16997-57 specifications NAS1352-4-6P, ensuring consistent quality for demanding industrial applications. The inch system measurement provides standardized compatibility with North American equipment and tooling. Material composition and plating comply with industrial standards for high-strength fasteners in critical assembly operations.
