Value Collection 99183 Hex Head Cap Screw 3/4-10 Grade 8 25 Pack

Product Description

The VALUE COLLECTION 99183 is a 3/4-10 x 5-1/2 inch hex head cap screw manufactured from Grade 8 steel with a bright, uncoated finish. It features partial threading along the shank and conforms to ASME B18.2.1 and SAE J429 standards, making it a high-strength fastener suited for demanding structural and mechanical assembly applications. The UNC thread form is the standard inch-series coarse thread, compatible with common tapping and nut stock. Sold in a package of 25, this screw is a practical choice for contractors, millwrights, maintenance technicians, and industrial assemblers who need consistent, specification-grade hardware on the job.

This fastener is used in heavy mechanical assemblies, structural steel connections, agricultural equipment, and general industrial fabrication where high clamping force and shear resistance are required. The partially threaded shank provides a smooth bearing surface in the grip zone, which reduces stress concentration in bolted joints under load. Applications typically include framing fixtures, machinery bases, conveyor structures, and similar assemblies where Grade 8 tensile strength is specified by the design.

Key Features

• 3/4-10 UNC thread size with 5-1/2 inch length measured under the head
• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank provides a clean grip zone in bolted joints
• Bright, uncoated finish — suitable where additional corrosion protection will be applied by the installer
• Meets ASME B18.2.1 and SAE J429 dimensional and material standards
• Sold in a package of 25 pieces for job-site or shop use

Compatibility

Designed for use with standard 3/4-10 UNC hex nuts, flat washers, and lock washers in inch-series bolted assemblies. Compatible with any application calling for a Grade 8 hex cap screw per ASME B18.2.1 or SAE J429.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or structural assembler following the applicable torque specifications for Grade 8 fasteners as published in engineering references or the project specification. Always use a calibrated torque wrench and confirm the mating nut and hole are free of debris before assembly. Do not install Grade 8 fasteners with impact tools set above recommended snug-tight levels without a controlled torque verification step. Consult AISC or applicable structural codes when using these fasteners in load-bearing steel connections.
