Value Collection 015259PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The Value Collection 015259PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and equipment fabrication. Built from alloy steel with a black oxide finish, this screw delivers corrosion resistance and a low-reflectance appearance suited to industrial environments. The 3/8-16 UNC thread size and 1-1/2-inch length under head make it a common choice in medium-duty structural connections. Drive engagement is through a 5/16-inch hex socket, allowing controlled torque application with standard Allen keys or hex-bit drivers. Fully threaded along its length, the screw provides maximum thread engagement in through-hole and tapped-hole configurations. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards.

This screw is well suited for machine shop work, fixture building, equipment maintenance, and industrial assembly. Fully threaded construction makes it appropriate for use in tapped blind holes or with a nut in clearance holes. The black oxide alloy steel construction holds up in moderate-exposure environments where mild rust resistance is needed without plating costs. Machinists, maintenance technicians, and fabricators regularly use this fastener type in both OEM production and field repair contexts.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes and hardware
• 1-1/2-inch length under head provides reliable grip in medium-thickness material
• Alloy steel construction rated to ASTM A574 for high tensile and proof load requirements
• Black oxide finish offers mild corrosion resistance and low-glare surface
• Fully threaded along entire length for maximum thread engagement
• 5/16-inch hex drive allows use with standard Allen wrenches and hex bit sets
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw for use in any tapped hole or through-hole application requiring an ASME/ANSI B18.3-compliant alloy steel socket head fastener.

Installation Notes

Installation is performed using a 5/16-inch hex key or hex socket driver. Ensure the mating tapped hole is clean and free of debris before threading. Applying thread lubricant or anti-seize may be appropriate depending on the base material and service environment. Always verify thread engagement depth is adequate for the load rating of the joint before final torque.
