Value Collection 451110PR Hex Cap Screw 1/2-13x10 Grade 8

Product Description

The VALUE COLLECTION 451110PR is a 1/2-13 x 10 inch hex head cap screw manufactured from Grade 8 steel with a bright, uncoated finish. This fastener features a partially threaded shank conforming to ASME B18.2.1 standards for inch-series hex cap screws. The 1/2-13 designation indicates a half-inch nominal diameter with 13 threads per inch on a UNC thread form. Grade 8 steel provides high tensile strength suitable for demanding structural and mechanical connections. It weighs 0.57 pounds. Mechanical contractors, millwrights, equipment installers, and industrial maintenance technicians are the primary installers of this fastener class.

This cap screw is suited for use in heavy equipment assembly, structural steel connections, machinery mounting, and high-load mechanical joints where Grade 8 tensile strength is required. The partially threaded shank allows for a smooth bearing surface in applications requiring a grip length, which is common in bolted flange connections, shaft mountings, and thick-section assemblies. The uncoated finish is appropriate for dry indoor environments or applications where a field-applied coating or zinc plating is specified separately.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank provides a smooth grip section for precise bearing applications
• UNC 1/2-13 thread form for broad compatibility with standard inch-series nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards for hex cap screws
• 3/4 inch hex key size for use with standard hex wrenches and sockets
• Bright uncoated finish for applications where coating is not required or will be applied in the field

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 1/2-13 UNC tapped hole or hex nut conforming to ASME B18.2.1 specifications.

Installation Notes

Installation is performed by qualified mechanical, structural, or industrial maintenance technicians. Torque to the value specified by the joint design engineer or equipment manufacturer for Grade 8, 1/2-13 fasteners. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Do not substitute a lower-grade fastener in applications engineered for Grade 8 tensile requirements.
