Value Collection C703506 Hex Head Cap Screw 3/4-10 Grade 8

Product Description

The VALUE COLLECTION C703506 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with no finish coating, this fastener delivers superior tensile and proof load performance compared to lower-grade hardware. The 3/4-10 UNC thread size and 1-3/4 inch length under head make it suitable for bolted connections requiring reliable clamping force under heavy load. It conforms to ASME B18.2.1 dimensional standards, ensuring consistent fit across standard hex tooling and hardware. Each package contains 25 pieces.

This cap screw is used in heavy equipment assembly, structural steel connections, industrial machinery mounting, and similar applications where Grade 8 strength is specified. The uncoated finish is appropriate for indoor or controlled-environment installations or wherever additional plating or coating will be applied on-site. Trades and fabricators working to engineered fastener specifications will find the ASME B18.2.1 conformance useful for documented assemblies. The fully threaded shank maximizes thread engagement across the full length under head, which is preferred in through-bolt and nut-and-bolt configurations.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Fully threaded shank for maximum thread engagement over the full 1-3/4 inch length
• 3/4-10 UNC thread standard for broad compatibility with standard nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards
• Uncoated finish suitable for painted, plated, or controlled-environment use
• Sold in a 25-piece package for jobsite or shop use

Compatibility

Designed for use with standard 3/4-10 UNC hex nuts, flat washers, and lock washers in bolted assemblies conforming to inch-series fastener specifications.

Installation Notes

Installation should be performed by qualified mechanical or structural tradespeople using calibrated torque tooling appropriate for Grade 8 fasteners. Always consult the engineering specification or fastener torque chart for the required clamp load before final tightening. Do not mix Grade 8 bolts with lower-grade nuts, as mismatched hardware can reduce joint integrity. Inspect threads for damage before installation and replace any fastener showing signs of corrosion, deformation, or thread galling.
