Value Collection MP39114 Hex Cap Screw 1/2-13 X 3-1/2 in Grade 8

Product Description

The VALUE COLLECTION MP39114 is a Grade 8 steel hex head cap screw with a 1/2-13 UNC thread size and a 3-1/2 inch length under head. It features a zinc yellow dichromate finish that provides corrosion resistance in demanding environments. The shank is partially threaded, conforming to ASME B18.2.1 dimensional standards. This fastener is sold in a 10-piece package and is suited for high-strength bolting applications in mechanical, structural, and industrial assembly work. Licensed tradespeople and maintenance professionals rely on Grade 8 hardware where tensile strength and dimensional consistency are non-negotiable.

This cap screw is appropriate for heavy-duty mechanical assemblies, equipment mounting, structural connections, and general industrial maintenance where high-strength inch-series fasteners are required. The 1/2-13 UNC thread profile is one of the most common coarse-thread configurations in North American trade work, making this screw a practical stock item for HVAC equipment mounting, plumbing supports, electrical enclosure installation, and general mechanical service. The partially threaded shank provides a smooth bearing surface for applications requiring a grip length.

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw conforming to ASME B18.2.1, suitable for use wherever inch-series Grade 8 fasteners are specified in mechanical or structural assemblies.

Installation Notes

Installation of Grade 8 fasteners should be performed by qualified tradespeople following applicable codes and equipment manufacturer specifications. Use the correct hex wrench or socket driver sized for a 1/2-inch hex head cap screw. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Do not substitute a lower-grade fastener in applications where Grade 8 is specified.
