Value Collection 451075PR Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 451075PR is a Grade 8 steel hex head cap screw sized 3/8-16 x 7-1/2 inches, designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. The partially threaded shank provides a smooth bearing surface along the grip length, which is critical in applications where shank loading or precise bolt alignment is required. Finished bright and uncoated, this fastener meets ASME B18.2.1 dimensional standards. It is driven with a 9/16-inch hex key or wrench and is well suited for use by mechanical contractors, millwrights, and maintenance technicians working in demanding load environments.

This cap screw is used in general industrial and commercial construction applications where high-tensile-strength fasteners are required. Grade 8 hardware is commonly specified for heavy equipment mounting, structural steel connections, and machinery assembly where standard Grade 5 fasteners are insufficient. The UNC (Unified National Coarse) thread form ensures broad compatibility with standard nuts and tapped holes in inch-series applications. This fastener is sold individually, with a minimum order quantity of 10 pieces.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank for accurate bolt positioning and shear resistance
• 3/8-16 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• Bright uncoated finish suitable for use in dry or controlled environments
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• Driven with a 9/16-inch wrench or socket for fast installation

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts, flat washers, and lock washers in inch-series assemblies. Suitable for any application requiring a Grade 8 partially threaded hex cap screw in 3/8-16 x 7-1/2 inch sizing.

Installation Notes

Installation is performed by mechanical and maintenance trades using standard hand or power tools with a 9/16-inch socket or open-end wrench. Always use a calibrated torque wrench when Grade 8 fasteners are specified to a torque value in the assembly drawing or service manual. Inspect mating threads for damage or contamination before installation. Do not use impact-only methods to achieve final torque on structural or critical-path fasteners.
