Value Collection 307130BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 307130BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 5/8-11 UNC thread size, a 1-1/2 inch length under head, and is fully threaded from head to tip. The 1/2 inch hex drive accepts a standard hex key or socket driver. Manufactured from alloy steel with a black oxide coating, this fastener meets ASTM A574 specifications for socket head cap screws. It is suited for applications requiring controlled torque fastening in tight or recessed mounting locations where a hex socket drive is preferred over an external drive type.

This screw is used across a wide range of industrial and mechanical maintenance applications, including equipment fabrication, machine tool assembly, hydraulic component mounting, and structural fastening where high tensile strength is required. The black oxide finish provides moderate corrosion resistance in dry or mildly humid indoor environments. Tradespeople, millwrights, machinists, and maintenance technicians commonly install these fasteners using a 1/2 inch hex key, Allen wrench, or socket driver bit. The fully threaded design ensures maximum thread engagement across the full grip length.

Key Features

• 5/8-11 UNC thread size with full threading from head to tip
• 1-1/2 inch length under head for consistent grip and engagement
• 1/2 inch internal hex drive for precise torque application in recessed or countersunk bores
• Alloy steel construction meets ASTM A574 socket head cap screw standard
• Black oxide coating for surface protection and reduced light reflection in tooling applications

Compatibility

Designed as an OEM-style replacement or standard-supply fastener for any application requiring a 5/8-11 UNC fully threaded hex socket cap screw conforming to ASTM A574.

Installation Notes

Installation should be performed by a qualified mechanic, machinist, or maintenance technician using a calibrated torque wrench and the appropriate 1/2 inch hex key or socket bit. De-energize and lock out all equipment before servicing any fastened assembly per applicable OSHA lockout/tagout procedures. Do not exceed the rated torque for the fastener grade and do not substitute this fastener in applications requiring a different thread class or material specification without engineering review. Inspect threads in the mating hole for damage or contamination before installation.
