Value Collection 451174BR Hex Head Cap Screw 7/8-14 X 8 in

Product Description

The VALUE COLLECTION 451174BR is a Grade 8 steel hex head cap screw sized 7/8-14 x 8 inches, designed for high-strength fastening applications in mechanical, industrial, and structural assemblies. The 7/8-14 designation indicates a 7/8-inch diameter with 14 threads per inch in the Unified National Fine (UNF) thread standard. At 8 inches in length under the head and partially threaded, this fastener is built for joints requiring a defined grip zone and superior clamping load. Licensed mechanics, millwrights, and maintenance technicians working with heavy equipment and structural connections will find this fastener appropriate for demanding torque and load requirements.

This cap screw is suited for heavy-duty bolted connections in industrial machinery, agricultural equipment, and structural fabrication where Grade 8 tensile strength is required. The bright, uncoated finish means this fastener is intended for use in controlled environments or applications where the installer will apply their own corrosion protection. Compliance with ASME B18.2.1 ensures dimensional consistency across interchangeable assemblies. The 5/8-inch hex key size allows use with standard open-end, box-end, and socket wrenches available in most trade toolkits.

Key Features

• Grade 8 steel construction for high-tensile, heavy-duty fastening applications
• 7/8-14 UNF thread provides finer thread pitch for improved torque control and vibration resistance
• Partially threaded shank creates a defined grip zone suitable for load-bearing joint designs
• Meets ASME B18.2.1 dimensional standards for consistent fit and interchangeability
• Bright, uncoated finish for use where coating is unnecessary or a customer-applied finish is planned
• 5/8-inch hex drive compatible with standard wrenches and sockets

Compatibility

Designed as an OEM-style replacement or direct-use fastener for heavy-duty bolted assemblies requiring a 7/8-14 UNF Grade 8 hex head cap screw with an 8-inch length under head.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople familiar with Grade 8 fastener torque requirements and joint design. Always consult the equipment manufacturer's torque specifications before tightening, as Grade 8 fasteners require precise preload to function correctly. De-energize, depressurize, or otherwise render safe any equipment before servicing fastened joints. Do not substitute a lower-grade fastener in an application specified for Grade 8.
