Value Collection 451229BR Hex Cap Screw 3/4-10x14 Grade 8

Product Description

The VALUE COLLECTION 451229BR is a Grade 8 steel hex head cap screw with a 3/4-10 UNC thread and a 14-inch length under head. Grade 8 designation indicates a high-strength carbon steel fastener capable of handling heavy load applications where lower-grade hardware would fail. The shank is partially threaded, leaving a smooth grip length that resists shear forces in bolted joints. The bright uncoated finish meets ASME B18.2.1 dimensional standards. This fastener is installed by millwrights, ironworkers, pipefitters, and maintenance technicians across industrial, structural, and mechanical equipment applications.

This cap screw is suited for heavy-duty bolted connections in structural assemblies, industrial machinery, agricultural equipment, and mechanical systems where high clamp load and tensile strength are required. The partially threaded design makes it appropriate for through-bolt applications where the smooth shank spans the joint interface. The 1-1/8 inch hex key size accommodates standard industrial impact wrenches and ratchets used in field and shop installations.

Key Features

• Grade 8 high-strength steel construction for demanding structural and mechanical applications
• 3/4-10 UNC thread for broad compatibility with standard inch-series nuts and tapped holes
• 14-inch length under head with partial threading for shear-resistant through-bolt installations
• Bright uncoated finish — no coating interference with torque or dimensional tolerances
• Conforms to ASME B18.2.1 dimensional standard for consistent fit and interchangeability
• 1-1/8 inch hex drive works with standard industrial wrenches and impact tooling

Compatibility

Designed as a standard inch-series hex head cap screw for use with 3/4-10 UNC nuts, washers, and tapped holes in structural and mechanical assemblies conforming to ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by qualified tradespeople following applicable structural or mechanical codes for the application. De-energize, depressurize, or lock out equipment before servicing any bolted connection. Use calibrated torque tooling appropriate for Grade 8 fasteners; consult the applicable engineering specification or equipment service manual for required clamp load values. Do not mix Grade 8 fasteners with lower-grade nuts or hardware in load-bearing joints.
