Value Collection 451035BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451035BR is a hex head cap screw designed for heavy-duty fastening applications in industrial, structural, and mechanical assemblies. It features a 1-1/4-7 UNC thread size with a 6-1/2 inch length under head, partial threading, and is manufactured from Grade 8 steel with a bright uncoated finish. This fastener meets ASME B18.2.1 standards, making it suitable for high-strength bolted connections that require reliable clamping force. Installers and maintenance professionals working on structural steel, heavy equipment, or machinery will find this screw well-suited to demanding load requirements.

This hex head cap screw is used in a wide range of industrial and trade applications where high-tensile fasteners are required. Typical installations include structural steel connections, heavy equipment frames, agricultural machinery, and industrial manufacturing assemblies. The partial threading allows for greater shank strength and is appropriate for through-bolt applications where the full grip length of the fastener is needed to clamp two or more components together. It is commonly specified in maintenance, repair, and original equipment manufacturing contexts.

Key Features

• Grade 8 steel construction for high tensile strength in demanding fastening applications
• 1-1/4-7 UNC thread size with partial threading for maximum shank integrity
• 6-1/2 inch length under head suits deep-grip structural and mechanical assemblies
• Bright uncoated finish maintains dimensional accuracy for close-tolerance fits
• Conforms to ASME B18.2.1 standard for dimensional consistency and quality assurance
• Hex key size of 1-11/16 inches accommodates standard heavy-duty wrenching tools

Compatibility

Designed as a high-strength replacement or original-install fastener for applications requiring a 1-1/4-7 UNC partially threaded hex head cap screw conforming to ASME B18.2.1 in Grade 8 steel.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with high-strength fastener procedures. Always de-energize or shut down the equipment being serviced before removing or installing structural fasteners. Use a properly sized 1-11/16 inch wrench or socket to drive the fastener. Refer to the applicable equipment manufacturer torque specifications and any relevant industry standards for proper preload requirements.
