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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread — standard inch-series profile for broad tool compatibility\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch length under head with partially threaded shank for grip-length applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eSold in a 10-piece package with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned 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.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of Grade 8 fasteners should be performed by qualified tradespeople following applicable codes and equipment manufacturer specifications.
