Value Collection 451022BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451022BR is a partially threaded hex head cap screw designed for high-strength fastening applications. Manufactured from Grade 8 steel with a bright, uncoated finish, this fastener meets ASME B18.2.1 standards. It features a 1-1/8-12 UNF thread size, a 6-1/2-inch length under head, and a 1-11/16-inch hex key size. At 2.18 pounds, this is a heavy-duty fastener suited to demanding structural, mechanical, and industrial assemblies where precise thread engagement and tensile strength are critical.

This cap screw is used in heavy equipment maintenance, industrial machinery assembly, structural fabrication, and similar trades where Grade 8 fasteners are specified. The UNF thread form and partial threading make it appropriate for applications requiring fine-pitch engagement into blind or through-tapped holes. It is commonly installed by millwrights, pipefitters, maintenance mechanics, and general contractors working on steel structures or heavy mechanical systems.

Key Features

• Grade 8 steel construction for high tensile strength and shear resistance
• 1-1/8-12 UNF thread form with partial threading for precise engagement
• 6-1/2-inch length under head accommodates thick material stacks
• Bright, uncoated finish suitable for indoor or controlled-environment applications
• Meets ASME B18.2.1 dimensional standards
• 1-11/16-inch hex drive size compatible with standard industrial wrenching tools

Compatibility

Designed as a standard-dimension Grade 8 hex head cap screw conforming to ASME B18.2.1, suitable for use in any application specifying a 1-1/8-12 UNF partially threaded hex cap screw.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with Grade 8 fastener specifications and torque requirements for the application. Use a properly sized wrench or socket for the 1-11/16-inch hex drive to avoid rounding the head. Ensure mating threads are clean and free of debris before installation. Follow the equipment manufacturer or engineering specification for torque values, as none are supplied with this fastener listing.
