Value Collection C703610 Hex Head Cap Screw 7/8-9

Product Description

The VALUE COLLECTION C703610 is a Grade 8 steel hex head cap screw sized at 7/8-9 thread by 2-3/4 inches under the head. It features a Unified National Coarse (UNC) thread form and is partially threaded along the shank. The uncoated finish leaves the steel bare, making it suitable for applications where a coating would interfere with fit or where a secondary finish will be applied in the field. Manufactured to ASME B18.2.1 and SAE J429 standards, this fastener meets the dimensional and mechanical requirements expected in structural and heavy-duty mechanical assembly work.

This cap screw is used in industrial, mechanical, and structural assembly applications where high-strength fastening is required. Grade 8 hardware is commonly specified in heavy equipment, machinery frames, agricultural implements, and structural steel connections. The partial threading allows the unthreaded shank to bear shear loads in close-tolerance bored holes, a common requirement in OEM fabrication and maintenance repair operations. Licensed tradespeople and journeyman-level mechanics working in industrial maintenance, machine shops, and field service will encounter this fastener specification routinely.

Key Features

• Grade 8 steel construction meets SAE J429 mechanical property requirements for high-strength fastening
• 7/8-9 UNC thread form for broad compatibility with standard inch-pattern nuts and tapped holes
• Partially threaded shank allows the bolt body to carry shear loads in precision-bored applications
• Uncoated finish for use where plating is not required or a field-applied finish will follow
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws
• Sold in a package quantity of 10, with a minimum order quantity of 1

Compatibility

Designed as a standard-dimension hex head cap screw conforming to ASME B18.2.1 and SAE J429, suitable for use with any 7/8-9 UNC-threaded nut or tapped hole in Grade 8-appropriate structural or mechanical applications.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople familiar with fastener torque specifications for Grade 8 hardware at the 7/8-9 thread size. Always verify that the mating nut or tapped hole is rated for Grade 8 load levels before assembly. Consult applicable engineering drawings or fastener torque tables for the correct clamp load target — do not estimate torque by feel on structural connections. Inspect threads for damage and ensure proper thread engagement before final tightening.
