Value Collection 451400BR Hex Head Cap Screw 1-14 X 15 in

Product Description

The VALUE COLLECTION 451400BR is a Grade 8 steel hex head cap screw designed for high-strength bolted connections in demanding mechanical and structural applications. Measuring 15 inches in length under the head with a 1-14 UNF thread size, this fastener is partially threaded and left uncoated (bright finish). Grade 8 steel delivers significantly higher tensile strength than standard hardware grades, making it appropriate for heavy-duty assemblies where fastener integrity is critical. Licensed tradespeople, millwrights, and maintenance mechanics working on industrial equipment, heavy machinery, and structural steel assemblies rely on this class of fastener.

This cap screw is suited for applications requiring a fine-thread, large-diameter fastener with a controlled grip length. The partial threading provides a smooth shank section that resists shear loads along the bolt body, which is useful in joints subject to lateral forces. Typical install environments include industrial machinery frames, agricultural equipment, large hydraulic assemblies, and structural connections where Grade 8 rated hardware is specified by design. The bright uncoated finish is appropriate for indoor or protected installations where corrosion exposure is minimal.

Key Features

• Grade 8 steel construction for high tensile strength in demanding bolted joints
• 1-14 UNF thread provides fine-thread engagement for improved torque control and vibration resistance
• Partially threaded shank resists shear loading along the bolt body
• 15-inch length under head accommodates thick assemblies and long grip-length requirements
• Bright uncoated finish conforms to ASME B18.2.1 dimensional standards
• Hex key drive size of 1-1/2 inches for use with standard heavy-hex tooling

Compatibility

Designed as an OEM-style replacement or new-installation fastener for applications specifying a 1-14 UNF Grade 8 hex head cap screw per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with torque specifications and fastener grades appropriate to the joint design. Always de-energize and lock out machinery before servicing fasteners on powered equipment. Use a properly sized 1-1/2-inch hex socket or wrench to avoid fastener head damage. Follow the engineer of record or equipment manufacturer torque specifications for Grade 8 hardware of this diameter.
