Value Collection 451197BR Hex Head Cap Screw 1-14 X 9 in

Product Description

The VALUE COLLECTION 451197BR is a Grade 8 steel hex head cap screw designed for heavy-duty fastening applications requiring high tensile strength. Measuring 1-14 thread size with a 9-inch length under the head, this fastener is partially threaded and finished bright uncoated. It conforms to ASME B18.2.1 dimensional standards and uses a Unified Fine (UNF) thread standard, making it suitable for precision mechanical assemblies where controlled fit and high clamping force are required. Licensed trades and industrial maintenance professionals rely on Grade 8 fasteners when joint integrity under dynamic or high-load conditions is critical.

This cap screw is appropriate for use in structural, mechanical, and industrial assemblies where a coarse-grade fastener would be undersized for the load. The partially threaded shank provides a bearing surface that resists shear loads, making it well-suited for bolted connections in heavy equipment, agricultural machinery, and industrial fabrication. It is sold individually and is compatible with standard 1-14 UNF hex nuts and washers. A 1-1/2-inch hex key or wrench is required for installation.

Key Features

• Grade 8 steel construction for high tensile and proof load capacity
• 1-14 UNF thread for fine-pitch, precision engagement
• 9-inch length under head accommodates thick or stacked material assemblies
• Partially threaded shank provides shear resistance in bolted joints
• Bright uncoated finish — suitable for applications where coating-free contact is required or where field coating will be applied
• Conforms to ASME B18.2.1 for dimensional consistency

Compatibility

Designed for use with standard 1-14 UNF threaded nuts, plates, and tapped assemblies conforming to ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by qualified mechanical or industrial trades familiar with high-strength fastener torque requirements for Grade 8 hardware. Always use a calibrated torque wrench and consult the applicable engineering specification or equipment service manual for the required clamp load — do not estimate torque for Grade 8 joints. Ensure mating threads are clean and free of debris before assembly. A 1-1/2-inch hex wrench or socket is required to drive this fastener.
