Value Collection 451001BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451001BR is a fully threaded hex head cap screw sized 1-1/8-7 UNC by 2-1/2 inches under head. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets the ASME B18.2.1 standard for inch-series hex cap screws. The Grade 8 rating indicates a high-strength fastener suited for demanding structural and mechanical applications. It weighs approximately 1.05 pounds. Licensed tradespeople and industrial maintenance technicians reach for this fastener when a reliable, full-thread engagement is required in heavy-duty assemblies.

This cap screw is used in mechanical, structural, and industrial maintenance applications where high-tensile, inch-series fasteners are specified. Typical scenarios include equipment mounting, frame assembly, and field repair work across HVAC, plumbing, electrical, and general mechanical trades. The fully threaded shank provides maximum thread engagement for the full grip length, making it well suited for short-bolt applications and through-bolted joints where clamping force is critical.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Fully threaded shank for maximum thread engagement over the entire 2-1/2 inch length under head
• 1-1/8-7 UNC thread series per ASME B18.2.1 standard
• Bright uncoated finish — suitable for use with customer-applied coatings or in dry indoor environments
• 1-11/16 inch hex key size for use with standard wrenching tools
• Sold individually — no minimum overage required

Compatibility

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

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with high-strength fastener procedures. Always de-energize, depressurize, or otherwise make safe any equipment before replacing or installing structural fasteners. Use a properly sized 1-11/16 inch wrench or socket to avoid rounding the hex head. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
