Value Collection 33676 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 33676 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 1/2-13 UNC thread size with a 5-inch length under the head and is partially threaded. The drive is a 3/8-inch hex socket. Constructed from alloy steel with a black oxide finish coating, this fastener meets ASME/ANSI B18.3 and ASTM A574 standards, confirming its suitability for demanding load-bearing connections. It is installed using a standard 3/8-inch hex key or Allen driver.

This screw is suited for use in machinery, equipment assemblies, fixtures, and fabricated steel structures where a recessed-drive, high-strength fastener is required. The partial threading provides a smooth shank section that is useful for applications requiring precise alignment or shear load transfer. Facilities maintenance technicians, millwrights, machinists, and general contractors commonly use this fastener type across a wide range of industrial and commercial applications.

Key Features

• 1/2-13 UNC thread for compatibility with standard inch-series tapped holes
• 5-inch length under head with partial threading for shank-guided installations
• 3/8-inch hex socket drive for secure torque application
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 1/2-13 UNC threaded fastener in an alloy steel, black oxide finish per ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation requires a 3/8-inch hex key or Allen driver. Ensure the mating tapped hole is clean, properly sized, and free of debris before driving. Power down or de-energize any equipment before fastener replacement in live machinery. Follow applicable torque guidelines from the equipment manufacturer or relevant industry standards for 1/2-13 UNC alloy steel fasteners.
