Value Collection 581652PR Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 581652PR is a hex socket cap screw designed for high-strength fastening in mechanical assemblies, tooling fixtures, and structural applications. This fully threaded fastener features a 5/8-11 UNC thread and a 7/8-inch length under head. The drive is a 1/2-inch internal hex socket, requiring a standard hex key or Allen-style driver. Constructed from alloy steel with a black oxide finish, it delivers elevated tensile strength and moderate corrosion resistance. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding industrial and maintenance applications.

This fastener is used in a wide range of industries including manufacturing, general maintenance, and mechanical assembly. The 5/8-11 UNC thread is a coarse-thread specification common in machine building, equipment repair, and fixture construction. The black oxide finish reduces light reflection and provides mild rust inhibition in low-moisture environments. Machinists, millwrights, and maintenance technicians typically install this screw when a low-profile, high-clamping-force fastener is required in tight or recessed locations.

Key Features

• 5/8-11 UNC fully threaded coarse-thread specification
• 7/8-inch length under head for shallow fastening depths
• 1/2-inch internal hex socket drive for precise torque application
• Alloy steel construction for high tensile strength per ASTM A574
• Black oxide finish for mild corrosion resistance and reduced glare
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for 5/8-11 UNC threaded holes in metalworking, machinery, and general industrial assembly applications.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or Allen driver. Always verify that the mating threaded hole is clean and free of debris before driving the fastener. De-energize and lock out any equipment before accessing fastener locations on live machinery. Follow the equipment manufacturer torque specifications and applicable ASME standards for final seating.
