Value Collection 451226BR Hex Head Cap Screw 3/4-10 X 13 in

Product Description

The VALUE COLLECTION 451226BR is a Grade 8 steel hex head cap screw with a 3/4-10 UNC thread and a 13-inch length under head. Partially threaded and left with a bright, uncoated finish, this fastener is built for high-strength bolted connections in heavy-duty mechanical, structural, and industrial applications. It conforms to ASME B18.2.1 dimensional standards and requires a 1-1/8 inch hex key or wrench for installation. At 1.7 pounds, it is a substantial fastener suited to demanding load-bearing assemblies. Maintenance technicians, millwrights, pipefitters, and structural tradespeople are the primary installers.

This cap screw is appropriate for high-torque, high-load fastening tasks in commercial and industrial settings. Common applications include equipment mounting, structural steel connections, heavy machinery assembly, and pipe flange bolting where a large-diameter, long-length Grade 8 fastener is required. The partially threaded shank provides a bearing surface in the bolt hole, which is advantageous in lap-joint and shear-load scenarios where thread engagement must be limited to the nut zone.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• 3/4-10 UNC thread size with partial threading for controlled shank engagement
• 13-inch length under head accommodates deep stack or long-reach assemblies
• Bright, uncoated finish — suitable for indoor or controlled-environment installations
• Conforms to ASME B18.2.1 dimensional standards
• 1-1/8 inch hex drive for use with standard commercial hex wrenches and impact sockets

Compatibility

Designed as a standard ASME B18.2.1 hex head cap screw for use with any 3/4-10 UNC tapped hole or standard heavy hex nut in structural, mechanical, or equipment-mounting applications requiring Grade 8 strength.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or tradesperson familiar with high-strength fastener torque requirements. Power down or de-energize any associated equipment and relieve system pressure before replacing structural fasteners. Use a calibrated torque wrench to achieve the proper clamp load for Grade 8 hardware per applicable engineering specifications or applicable codes. Never reuse fasteners that show signs of thread damage, necking, or corrosion.
