Value Collection 307151BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 307151BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 5/8-11 UNC thread size and measures 5-1/2 inches in length under the head, making it suitable for deep-reach bolting in heavy-duty equipment. The screw is partially threaded and driven with a 1/2-inch hex key. Constructed from alloy steel with a black oxide finish, it meets the ASTM A574 standard for socket head cap screws, which specifies high tensile strength and precise dimensional tolerances. Machinists, millwrights, and maintenance technicians typically work with this fastener class.

This screw is used in general industrial and mechanical assembly wherever a low-profile, high-torque fastener is required. Common applications include machine frames, fixture plates, tooling setups, pump housings, and fabricated structural components. The partially threaded shank provides a bearing surface in the clearance hole, which aids in precise alignment of mated components. The black oxide coating offers mild corrosion resistance and reduces surface reflectivity in precision environments.

Key Features

• 5/8-11 UNC thread size for heavy-duty fastening loads
• 5-1/2 inch length under head suits deep-reach bolting applications
• Partially threaded shank improves alignment in clearance holes
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and reduced glare
• 1/2-inch hex drive for use with standard hex keys or socket tooling

Compatibility

Designed as a standard ASTM A574 hex socket cap screw for use in any application requiring a 5/8-11 UNC partially threaded fastener with a 5-1/2-inch length under head.

Installation Notes

Installation requires a 1/2-inch hex key or Allen socket rated for the torque demands of a 5/8-11 UNC alloy steel fastener. De-energize, depressurize, or otherwise isolate the equipment before servicing fastened joints. Ensure mating threads are clean and free of debris before installation. Follow applicable industry standards and equipment manufacturer torque specifications when tightening.
