Value Collection 99184 Hex Head Cap Screw 3/4-10 X 6 in Grade 8

Product Description

The VALUE COLLECTION 99184 is a Grade 8 steel hex head cap screw sized 3/4-10 UNC thread by 6 inches under the head, supplied in a 25-piece pack. This is a heavy-duty fastener with a partially threaded shank, conforming to ASME B18.2.1 and SAE J429 standards. Grade 8 steel delivers high tensile strength, making it appropriate for demanding structural and mechanical connections in industrial, commercial, and trade applications. The uncoated finish means no additional corrosion protection is applied, which is standard when field painting, plating, or coating will be applied after installation.

This screw is used across a wide range of trade and industrial applications where high-strength inch-series fasteners are required. Typical installation scenarios include mechanical equipment mounting, structural steel connections, HVAC equipment frames, heavy machinery assembly, and general maintenance and repair in commercial or industrial facilities. The 3/4-10 UNC thread pattern is a widely used coarse-thread standard in North American trade work. The partially threaded shank provides a smooth bearing surface that improves clamping performance in bolted joint assemblies.

Key Features

• Grade 8 steel construction for high tensile and proof load strength per SAE J429
• 3/4-10 UNC coarse thread, partially threaded shank for improved clamping
• 6-inch length measured under the head per ASME B18.2.1
• Uncoated finish — compatible with field-applied coatings or plating
• Meets ASME B18.2.1 and SAE J429 dimensional and material standards
• Supplied in a 25-piece pack for job-site or shop inventory

Compatibility

Designed as a standard inch-series hex head cap screw suitable for use with 3/4-10 UNC nuts and tapped holes in steel, iron, and other structural materials where Grade 8 fasteners are specified.

Installation Notes

Installation is performed by millwrights, ironworkers, pipefitters, HVAC mechanics, or general maintenance technicians depending on the application. Always verify that the mating nut or tapped hole is rated for Grade 8 loading before assembly. Use a calibrated torque wrench and apply the torque value specified by the equipment manufacturer or applicable structural code. Do not mix Grade 8 fasteners with lower-grade nuts, as this can lead to thread stripping or joint failure.
