Professional Applications & Engineering Value
Engineered for demanding industrial assemblies, these socket head cap screws deliver critical performance where failure is not an option. The cadmium-plated alloy steel construction provides an effective barrier against galvanic corrosion and chemical exposure, while the Class 3A thread fit maintains precise tolerances in vibration-prone equipment. The combination of 160,000 psi tensile strength and Rockwell C39 hardness ensures these fully threaded fasteners withstand extreme mechanical loads without deformation. Ideal for precision machinery, aerospace components, and automotive systems requiring reliable UNRC coarse threads for rapid maintenance access and secure fastening under dynamic operating conditions.
Specification Summary & Compliance
This 4-40 thread socket head cap screw features precise Class 3A thread fit per UNRC standards with coarse thread spacing and right-hand thread direction. Manufacturing complies with MS16997-10 specifications (equivalent to NAS1352-04-6P) for dimensional accuracy and performance verification. The 3/8" length and fully threaded design maintain consistent mechanical properties throughout the fastener. Materials and plating processes adhere to industrial standards for corrosion resistance and mechanical reliability in critical applications.
