Value Collection 451061BR Hex Cap Screw 1-1/2-6 X 5 in Grade 8

Product Description

The VALUE COLLECTION 451061BR is a heavy-duty hex head cap screw sized at 1-1/2-6 x 5 inches, manufactured from Grade 8 steel with a bright, uncoated finish. This fastener is partially threaded and conforms to ASME B18.2.1 standards, making it a reliable choice for high-tensile structural and mechanical assemblies. The UNC (Unified National Coarse) thread form ensures broad tooling compatibility and secure engagement in standard tapped holes. At 3.41 pounds, this is a substantial fastener intended for heavy industrial applications where clamping force and shear resistance are critical. It is installed using a 2-1/4-inch hex wrench or socket.

This cap screw is suited for heavy machinery, structural steel connections, industrial equipment, and high-load mechanical assemblies where Grade 8 tensile strength is required. The partially threaded shank provides a bearing surface that resists lateral shear forces, which is especially valuable in bolted joints that experience dynamic or cyclic loading. Maintenance technicians, millwrights, ironworkers, and industrial mechanics routinely use this size in fabrication, repair, and OEM assembly work.

Key Features

• Grade 8 steel construction for high tensile strength and load-bearing capacity
• Partially threaded shank provides a smooth bearing surface for shear-resistant joints
• UNC thread form for compatibility with standard tapped holes and hardware
• Conforms to ASME B18.2.1 for dimensional accuracy and interchangeability
• Bright, uncoated finish suitable for indoor or controlled-environment applications
• 2-1/4-inch hex drive for use with standard industrial sockets and wrenches

Compatibility

Designed as a standard UNC hex head cap screw for use in any application requiring a 1-1/2-6 thread, 5-inch grip length, and Grade 8 tensile rating in conformance with ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or ironworker using a properly rated torque wrench and a 2-1/4-inch hex socket. Always consult the applicable engineering specification or joint design document for the required torque value, as over- or under-torquing Grade 8 fasteners can compromise joint integrity. Inspect threads for damage before installation and ensure mating tapped holes or nuts are clean and free of debris. De-energize and lockout any equipment before fastener service where applicable.
