Value Collection 99188 Hex Head Cap Screw 3/4-10 X 8 in Grade 8

Product Description

The VALUE COLLECTION 99188 is a 3/4-10 x 8 inch Grade 8 steel hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assembly work. The screw features a partially threaded shank, which provides a smooth bearing surface along the grip length and helps resist shear loads in bolted joints. It conforms to ASME B18.2.1 and SAE J429 standards, confirming it meets established dimensional and mechanical requirements for Grade 8 fasteners. The uncoated finish leaves the bare steel surface exposed and is suitable for applications where a topcoat or customer-applied finish will be used.

This hex head cap screw is suited for heavy-duty bolted connections in industrial machinery, agricultural equipment, structural steel fabrication, and general mechanical assembly. The 3/4-10 UNC thread size and 8-inch length under head make it appropriate for thick or stacked material joints where additional grip length is needed. Sold in packages of 10, it is a practical choice for maintenance shops, contractors, and fabricators who need reliable high-tensile hardware on hand.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank provides a smooth grip zone to resist shear forces
• 3/4-10 UNC thread standard ensures broad compatibility with standard hex nuts and tapped holes
• Conforms to ASME B18.2.1 and SAE J429 dimensional and mechanical standards
• Uncoated finish suitable for use where painting, plating, or lubrication will be applied at installation
• Packaged in quantities of 10 for job-site and shop use

Compatibility

Designed for use with standard 3/4-10 UNC hex nuts, washers, and tapped holes conforming to ASME B18.2.1 specifications in inch-measurement fastener assemblies.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or structural ironworkers using a standard 1-1/8 inch hex wrench or impact socket. Always use a flat washer under the head when bearing on soft or irregular surfaces. Follow the applicable torque specifications from the joint designer or equipment manufacturer for Grade 8 fasteners at 3/4-10 thread size, as no torque value is specified by this product listing. Inspect threads and mating hardware for damage before assembly.
