Value Collection 451005BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451005BR is a Grade 8 steel hex head cap screw with a 1-1/8-7 UNC thread size and a 4.5-inch length under head. Manufactured to ASME B18.2.1 standards, this fastener is partially threaded and supplied with a bright, uncoated finish. Grade 8 steel provides high tensile strength suitable for demanding structural and mechanical bolting applications. It is driven with a 1-11/16-inch hex key and is sold individually. Maintenance technicians, millwrights, and general contractors commonly use fasteners of this grade in heavy-duty assemblies where bolt preload and joint integrity are critical.

This cap screw is appropriate for use in industrial equipment, structural steel connections, heavy machinery, and similar high-load fastening applications. The UNC thread form is standard across North American trade applications, making this fastener widely compatible with matching Grade 8 or equivalent nuts and tapped holes in the 1-1/8-7 thread size. It is suited to both original equipment and field repair scenarios where a high-strength inch-series cap screw is specified.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank for controlled grip length in bolted joints
• ASME B18.2.1 dimensional standard compliance
• UNC thread form for broad compatibility with standard inch-series hardware
• Bright, uncoated finish suitable for use where coating is not specified
• 1-11/16-inch hex drive size for use with standard wrenches and sockets

Compatibility

Designed as a standard inch-series hex head cap screw for use with Grade 8-rated nuts and tapped holes sized to 1-1/8-7 UNC thread specification in structural, industrial, and mechanical applications.

Installation Notes

Installation should be performed by qualified maintenance or mechanical personnel familiar with bolted joint procedures. Ensure the mating thread and bearing surface are clean and free of debris before assembly. Apply any required lubrication or thread treatment per the applicable equipment specification. Always torque to the value specified by the equipment manufacturer or relevant structural standard for Grade 8 fasteners of this diameter.
