Partially threaded and supplied uncoated, this fastener meets ASME B18.2.1 dimensional standards for inch-series hex cap screws. Grade 8 alloy steel delivers high tensile strength, making it appropriate for structural, mechanical, and heavy-duty equipment assemblies. Machinists, millwrights, pipefitters, and general maintenance tradespeople use this screw wherever a reliable, high-strength hex drive fastener is specified. The 1\/2-13 UNC thread designation indicates a coarse thread series, which is standard in most domestic heavy equipment and industrial framing applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in industrial machinery, structural steel connections, HVAC equipment mounting, and heavy mechanical assemblies where Grade 8 strength is specified. The partially threaded shank provides a grip length that transfers shear load through the unthreaded section, which is a common engineering requirement in bolted joints. Sold in a package quantity of 25, it is practical for both single-job use and small-quantity stocking. Applications span commercial construction, equipment fabrication, and maintenance repair operations across multiple trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread for broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e2.75-inch length under head with partial threading to provide a load-bearing grip section\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for applications where a specific plating or coating will be applied or is not required\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standard for hex cap screws\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package to cover single jobs or low-quantity stocking needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with any 1\/2-13 UNC nut, threaded insert, or tapped hole conforming to ASME or UNC thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance tradespeople using a 3\/4-inch hex wrench or socket.
