Value Collection 451064BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451064BR is a heavy-duty hex head cap screw engineered for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at 1-1/2-6 thread with a 6-inch length under head, this screw is manufactured from Grade 8 steel and left with a bright, uncoated finish. The partially threaded shank provides a bearing surface for precision joint clamping. It conforms to ASME B18.2.1, making it a recognized standard for inch-series hex cap screws. Licensed tradespeople, millwrights, and maintenance mechanics routinely specify Grade 8 fasteners where tensile strength and shear resistance are critical.

This cap screw is suited for heavy industrial equipment, agricultural machinery, construction assemblies, and structural steel connections where high-load fastening is required. The UNC (Unified National Coarse) thread form ensures broad compatibility with standard tapped holes and nuts in inch-measurement systems. The bright, uncoated finish is appropriate for indoor or protected environments where corrosion exposure is minimal. Each unit is sold individually, making it easy to source a precise replacement quantity.

Key Features

• Grade 8 steel construction delivers high tensile strength for demanding load-bearing applications
• 1-1/2-6 UNC thread form is compatible with standard coarse-thread tapped holes and nuts
• Partially threaded shank provides a grip zone for proper joint clamping without full-thread engagement
• Bright, uncoated finish maintains dimensional accuracy with no coating buildup on threads
• Conforms to ASME B18.2.1 for dimensional consistency and interchangeability
• 6-inch length under head accommodates thick structural members and heavy-duty assemblies

Compatibility

Designed as a standard inch-series hex head cap screw for use with 1-1/2-6 UNC tapped holes, standard hex nuts, and heavy hex nuts in industrial and structural fastening applications.

Installation Notes

Installation is performed by millwrights, ironworkers, maintenance mechanics, or qualified tradespeople using appropriate hand or power tools rated for large-diameter fasteners. Always de-energize and lock out equipment before replacing fasteners in mechanical assemblies. Use a calibrated torque wrench to achieve the proper clamp load for Grade 8 fasteners as specified by the equipment manufacturer or applicable engineering standards. Do not substitute lower-grade fasteners in joints specified for Grade 8 material.
