Value Collection 99185 Hex Head Cap Screw 3/4-10 X 6-1/2 in Grade 8

Product Description

The VALUE COLLECTION 99185 is a 3/4-10 UNC hex head cap screw measuring 6-1/2 inches under the head, manufactured from Grade 8 steel with an uncoated finish. Grade 8 steel delivers a high tensile strength rating suited to heavy-duty bolted assemblies where standard fastener grades are insufficient. The partially threaded shank provides a clean bearing surface through the grip length, reducing the risk of thread engagement in areas not intended to be threaded. This fastener meets ASME B18.2.1 and SAE J429 standards, making it appropriate for structural, mechanical, and industrial fastening applications installed by maintenance technicians, millwrights, and mechanical contractors.

This cap screw is used in heavy equipment assembly, structural steel connections, machinery mounting, and industrial maintenance applications where Grade 8 strength is specified. The 3/4-10 UNC thread form is a common coarse-thread standard found across a wide range of industrial and OEM equipment. Partial threading is typical for longer fasteners in applications requiring precise shank fit through clearance holes or where the bolt must bear shear loads along the unthreaded portion.

Key Features

• Grade 8 steel construction meets high tensile and proof load requirements per SAE J429
• Partially threaded shank provides a clean grip section for shear-load and clearance-hole applications
• 3/4-10 UNC coarse thread is widely compatible with standard inch-series nuts and tapped holes
• Uncoated finish — suitable for use as-is or for plating and coating after installation where required
• Conforms to ASME B18.2.1 hex head dimensional standards
• Sold in a package quantity of 10 with a minimum order quantity of 1

Compatibility

Designed as an OEM-style and maintenance replacement fastener for any application requiring a 3/4-10 UNC hex head cap screw at 6-1/2 inches under the head in Grade 8 steel.

Installation Notes

Installation is performed by qualified maintenance technicians, millwrights, or mechanical contractors using a standard hex wrench or impact tool sized for a 3/4 inch fastener. Always verify the mating nut or tapped hole is rated for Grade 8 torque loads before assembly. De-energize, depressurize, or otherwise isolate the equipment before replacing or installing structural fasteners. Do not substitute a lower-grade fastener in any joint originally specified for Grade 8.
