Value Collection 011453BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 011453BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. It features a 5/8-18 UNF thread — a fine-pitch unified thread that provides greater tensile strength and better resistance to vibration loosening compared to coarse-thread equivalents. The screw measures 1-3/4 inches under the head and is fully threaded along that length. It is driven with a 1/2-inch hex (Allen) key. Constructed from alloy steel with a black oxide coating, it meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for structural and precision mechanical use.

This screw is commonly used in machine construction, fixture building, jig fabrication, and general industrial assembly wherever a socket-drive cap screw is specified. The fine 5/8-18 UNF thread pitch suits applications requiring tight clamping force or precise torque control. Machinists, millwrights, and maintenance technicians install this type of fastener in equipment frames, motor mounts, brackets, and similar assemblies. The black oxide finish provides moderate corrosion resistance and reduces surface reflectivity in low-visibility environments.

Key Features

• 5/8-18 UNF fine-thread specification for high tensile load and vibration resistance
• Fully threaded shank along the full 1-3/4 inch under-head length
• 1/2-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide coating for moderate corrosion protection and low-reflectance finish
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any application calling for a 5/8-18 UNF fully threaded socket cap screw in alloy steel.

Installation Notes

Installation is performed with a 1/2-inch hex key or Allen driver; use calibrated torque tools where assembly specifications require a defined clamp load. Ensure mating threads are clean and free of debris before installation. Follow applicable ASME or equipment OEM torque guidelines for 5/8-18 fasteners in the specific material being fastened. Alloy steel fasteners should not be mixed with dissimilar metals in corrosive environments without appropriate isolation.
