Value Collection 011249P Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 011249P is a hex socket cap screw designed for secure mechanical fastening in industrial, commercial, and trade applications. Sized at 3/8-16 UNC with a 5/8-inch length under the head, this fastener is fully threaded and driven with a 5/16-inch hex key. It is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, confirming its suitability for high-strength bolted connections. Machinists, millwrights, HVAC technicians, and equipment assemblers regularly specify this fastener type for structural and mechanical assemblies.

The 011249P is appropriate for use in machinery frames, equipment enclosures, pipe supports, and mechanical assemblies where a recessed hex drive is preferred over an external hex head. The fully threaded body maximizes thread engagement across the full grip length, making it well suited for thinner base materials or applications requiring maximum holding strength per unit of fastener length.

Key Features

• 3/8-16 UNC thread size for compatibility with standard inch-series threaded holes
• 5/8-inch length under head, fully threaded for maximum thread engagement
• 5/16-inch hex socket drive accepts standard Allen or hex key tools
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and a low-reflectance appearance
• Meets ASME/ANSI B18.3 dimensional standard for socket cap screws

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 3/8-16 UNC threaded fastener with a recessed hex drive.

Installation Notes

Installation requires a 5/16-inch hex key or Allen driver in good condition to avoid rounding the socket. Ensure the mating threaded hole is clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or relevant standards for 3/8-16 alloy steel socket cap screws. Black oxide finish offers limited corrosion protection — apply thread lubricant or anti-seize compound as required by the service environment.
