Value Collection 99174 Hex Head Cap Screw 3/4-10 X 2.5 in Grade 8

Product Description

The VALUE COLLECTION 99174 is a fully threaded hex head cap screw intended for heavy-duty mechanical and structural fastening applications. Manufactured from Grade 8 steel in an uncoated finish, this fastener carries a 3/4-10 UNC thread size with a 2.5-inch length under head. Grade 8 steel provides high tensile and proof load ratings, making it suitable for high-stress joints where fastener integrity is critical. It conforms to ASME B18.2.1 dimensional standards, ensuring consistent head geometry and thread form for use with standard tooling and hardware. Licensed trades and industrial mechanics rely on this grade for demanding assemblies.

This cap screw is appropriate for use in general industrial machinery, structural steel connections, heavy equipment assembly, and fabrication work where Grade 8 performance is required. The fully threaded shank engages the full length of the grip, making it well suited for applications using threaded inserts, nuts, or tapped holes where maximum thread engagement is needed. Sold in a package quantity of 25, it is a practical choice for service techs and tradespeople who need reliable hardware on hand for field or shop work.

Key Features

• Grade 8 steel construction delivers high tensile strength for demanding load-bearing joints
• Fully threaded shank provides maximum thread engagement across the full 2.5-inch length under head
• 3/4-10 UNC thread form compatible with standard nuts and tapped holes in inch-measurement applications
• Uncoated finish suitable for applications where additional coatings or plating will be applied post-assembly
• Conforms to ASME B18.2.1 for consistent dimensional tolerances across head height, width across flats, and thread form
• Packaged in quantities of 25 for efficient inventory management on the job or in the shop

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 3/4-10 UNC Grade 8 fastener per ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with fastener torque requirements for Grade 8 hardware. Always consult the equipment manufacturer's torque specifications before final tightening, as no torque values are supplied with this listing. Use the appropriate 6-point socket or open-end wrench sized for a 3/4-10 hex head to avoid rounding. Inspect threads for damage before installation and ensure mating threads are clean and free of debris.
