Value Collection 451006BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451006BR is a Grade 8 steel hex head cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. The fastener measures 1-1/8-7 in thread size with a 5-inch length under head and uses Unified National Coarse (UNC) thread form with partial threading. Manufactured to ASME B18.2.1 dimensional standards, this cap screw delivers the tensile strength and consistency required in demanding bolted joint applications. The bright uncoated finish is suitable for use where additional corrosion protection is applied at the assembly level or where bare steel is specified.

This cap screw is suited for heavy equipment assembly, structural fabrication, machinery mounting, and other applications requiring a high-strength inch-series fastener. The 1-1/8-7 UNC thread size and partial threading are typical of through-bolt and flange fastener applications in industrial and OEM environments. Installers working to torque specifications for Grade 8 hardware will find this fastener compliant with ASME B18.2.1 requirements. It is sold individually and can be ordered in the quantity needed for the job.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 1-1/8-7 UNC thread form per ASME B18.2.1 dimensional standard
• 5-inch length under head with partial threading for grip-length clearance
• Bright uncoated finish — accepts field-applied coatings or platings
• 1-11/16 inch hex drive size for use with standard heavy-hex tooling
• Weighs 1.75 pounds — suitable for torque calculations requiring fastener mass

Compatibility

Designed as a standard inch-series Grade 8 hex head cap screw for use in any application requiring a 1-1/8-7 UNC partially threaded fastener conforming to ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with Grade 8 fastener torque requirements and joint design. Always consult the equipment manufacturer or applicable engineering specification for the correct torque value before tightening. Use a calibrated torque wrench and the correct 1-11/16 inch hex socket or open-end wrench. Inspect threads for damage before installation and do not use lubricants unless specified by the joint design, as this affects torque-to-clamp-load relationships.
