Value Collection 99119 Hex Cap Screw 1/2-13 X 5-1/2 in Grade 8

Product Description

The VALUE COLLECTION 99119 is a Grade 8 steel hex head cap screw designed for high-strength fastening applications across industrial, mechanical, and construction environments. Sized at 1/2-13 x 5-1/2 inches with a partially threaded shank, this fastener follows UNC thread standards and meets ASME B18.2.1 dimensional specifications. The uncoated finish makes it suitable for applications where post-installation coating or plating is applied by the end user. Sold in a pack of 25, it is commonly specified by maintenance technicians, millwrights, pipefitters, and mechanical contractors who need reliable high-tensile fasteners in quantity.

This hex cap screw is suited for heavy-duty bolted assemblies where Grade 8 tensile strength is required. The partially threaded shank allows the unthreaded portion to bear shear loads in close-tolerance holes, a feature commonly specified in structural connections, machinery frames, equipment mounting, and flange assemblies. The 1/2-13 UNC thread is one of the most widely used coarse-thread sizes in the trade, compatible with standard 1/2-13 nuts, threaded inserts, and tapped holes across a broad range of equipment and structural components.

Key Features

• Grade 8 steel construction delivers high tensile strength for demanding bolted connections
• Partially threaded shank transfers shear loads through the unthreaded body section
• 1/2-13 UNC thread is a standard coarse-thread size compatible with widely available hardware
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• Uncoated finish allows field coating, plating, or use in dry indoor installations
• Pack of 25 supports job-site and shop inventory needs

Compatibility

Designed for use with standard 1/2-13 UNC nuts, threaded inserts, and tapped holes. Fits any application requiring a Grade 8, 1/2-13 x 5-1/2 inch partially threaded hex cap screw conforming to ASME B18.2.1.

Installation Notes

Installation is performed by millwrights, pipefitters, mechanical contractors, or maintenance technicians using standard hex wrenches or impact sockets sized for 1/2-13 fasteners. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Do not mix Grade 8 fasteners with lower-grade nuts or hardware, as mismatched grades can compromise joint integrity. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for the specific joint design.
