Value Collection 451008BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451008BR is a partially threaded hex head cap screw designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. It measures 1-1/8-7 UNC thread size with a 6-inch length under head, conforming to ASME B18.2.1 dimensional standards. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener delivers high tensile strength suitable for demanding bolted connections. The hex drive requires a 1-11/16-inch hex key or wrench. Licensed trades and mechanical contractors working on equipment mounting, structural connections, and machinery maintenance rely on this grade for high-load fastening where torque retention matters.

This cap screw is suited for industrial maintenance, heavy equipment assembly, and structural steel work where Grade 8 tensile ratings are specified. The partially threaded shank provides a bearing surface in the grip area, making it appropriate for shear-loaded joints and precision-fit bolt applications. It is sold individually and fits standard UNC-tapped holes at the 1-1/8-7 thread pitch.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• Partially threaded shank provides shear resistance in grip zone
• Conforms to ASME B18.2.1 for dimensional consistency
• UNC thread standard at 1-1/8-7 thread pitch
• Bright uncoated finish suitable for indoor or protected environments
• Requires 1-11/16-inch hex wrench for installation

Compatibility

Designed for use in standard UNC-tapped holes at 1-1/8-7 thread pitch per ASME B18.2.1. Suitable for applications where Grade 8 fasteners are called out in engineering specifications or equipment service manuals.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using calibrated torque equipment appropriate for Grade 8 fasteners at this diameter. Clean and inspect the tapped hole before installation to ensure thread integrity. Apply thread lubricant only if specified by the equipment manufacturer, as dry torque values differ from lubricated values. Follow all applicable machinery safety procedures and de-energize or lock out equipment before performing fastener service.
