Value Collection 307228BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 307228BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. Manufactured from alloy steel with a black oxide coating, this fastener meets ASTM A574 specifications for socket head cap screws, making it suitable for demanding load-bearing connections. It features a 1-8 UNC thread size, a 2-inch length under head, and a 5/8-inch hex drive. Fully threaded along the shank, it provides maximum thread engagement across the full clamping length. The black oxide finish offers mild corrosion resistance and reduces light reflection in precision applications.

This screw is used in general industrial, manufacturing, and maintenance applications where a recessed drive is required for flush or countersunk installations. The 1-8 UNC coarse thread is common in heavy-duty machine assemblies, jig and fixture construction, and equipment repair. The hex socket drive allows installation in tight clearance areas where a standard hex head wrench cannot reach. Mechanical assemblers, machinists, and maintenance technicians are the typical installers for this fastener type.

Key Features

• 1-8 UNC coarse thread for strong thread engagement in steel and alloy components
• Fully threaded shank provides maximum clamping force over the full 2-inch length under head
• Alloy steel construction meets ASTM A574 socket head cap screw standard
• Black oxide coating provides mild corrosion resistance and a low-glare finish
• 5/8-inch hex socket drive for use with standard Allen or hex key tooling

Compatibility

Designed as a standard ASTM A574 hex socket cap screw in 1-8 UNC thread, suitable for use in threaded bores or with compatible hex nuts in general industrial and mechanical assembly applications.

Installation Notes

Installation requires a 5/8-inch hex key or Allen driver. Ensure the mating threaded hole or nut is clean and free of debris before installation. Power down all equipment and relieve any mechanical load or pressure before replacing fasteners in active assemblies. Do not exceed the rated capacity of the thread engagement by under-torquing or over-torquing beyond tool manufacturer recommendations.
