Value Collection 015423BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 015423BR is a partially threaded hex socket cap screw designed for high-strength bolted connections in mechanical, industrial, and structural assemblies. It features a 5/8-11 UNC thread size, a 2-3/4 inch length under head, and a 1/2 inch hex drive for use with standard hex keys or Allen-style drivers. The body is machined from alloy steel and finished with a black oxide coating to provide mild corrosion resistance and a uniform dark appearance. This screw meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a recognized choice for precision fastening work in demanding environments.

This screw is suited for use in machine assemblies, manufacturing fixtures, tooling setups, and general industrial maintenance applications where a low-profile cap head and internal hex drive are required. The partial threading allows for greater shank engagement in through-bolt configurations and helps prevent thread stripping in deep blind holes. Machinists, maintenance technicians, and industrial assembly workers are the typical installers. It is appropriate for both original equipment assembly and field repair work.

Key Features

• 5/8-11 UNC thread form for broad compatibility with standard inch-series tapped holes
• Partially threaded shank provides strong clamping load and reduces risk of thread galling
• 1/2 inch hex socket drive accepts standard hex keys and socket drivers
• Alloy steel construction delivers high tensile and shear strength
• Black oxide finish adds mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for applications requiring a 5/8-11 UNC partially threaded hex socket cap screw with a 2-3/4 inch length under head conforming to ASME/ANSI B18.3 dimensional standards.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a calibrated hex key or T-handle driver sized to 1/2 inch. Ensure the mating tapped hole is clean, free of debris, and cut to the correct thread class before driving the fastener. Do not exceed the recommended seating torque for the fastener grade and material pairing, and consult applicable fastener torque tables for the specific joint design. Where applicable, follow relevant ASME or OSHA fastener safety guidelines for the assembly.
