Value Collection 015439BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 015439BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This fastener features a 5/8-11 UNC thread size with a 6-inch length under the head and a 1/2-inch hex drive socket. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and surface hardness suited to demanding service conditions. Partially threaded along its length, it allows for clamping force over unthreaded shank sections. Licensed tradespeople and maintenance machinists working on heavy equipment, tooling fixtures, and structural frames are the primary installers.

This screw fits applications requiring a coarse 5/8-11 UNC thread engagement, commonly found in machine tool assemblies, industrial equipment frames, conveyor systems, and structural steel fabrication. The black oxide alloy steel construction makes it well suited for dry indoor environments or lightly oiled assemblies where moderate corrosion protection is acceptable. The partially threaded shank design provides accurate alignment and strong clamping across thicker joined materials, a common requirement in heavy-duty mechanical and maintenance work.

Key Features

• 5/8-11 UNC coarse thread for strong engagement in standard inch-series tapped holes
• 6-inch length under head accommodates thicker assemblies and stacked material joints
• 1/2-inch hex socket drive for use with standard hex keys and socket-drive tooling
• Partially threaded shank provides shear strength and accurate bore alignment
• Alloy steel construction meets ASTM A574 and ASME/ANSI B18.3 fastener standards
• Black oxide finish reduces surface reflectivity and offers light corrosion resistance

Compatibility

Designed as an OEM-style replacement or standard service fastener for any application requiring a 5/8-11 UNC partially threaded hex socket cap screw conforming to ASME/ANSI B18.3, ASTM A574, and IFI 124 standards.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a properly sized 1/2-inch hex key or socket drive tool. De-energize and lock out all equipment before fastener replacement per applicable OSHA lockout/tagout procedures. Apply thread lubricant or anti-seize compound where specified by the equipment manufacturer to achieve accurate clamp load. Do not over-torque; consult the equipment service manual for the correct torque specification for 5/8-11 UNC alloy steel fasteners in the given joint material.
