Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade alternatives. It features a 1\/2-13 UNC thread size and a 2-1\/2 inch length under head, making it a reliable choice for bolted connections that require a controlled clamp load. Conforms to ASME B18.2.1 standards. Installed by millwrights, maintenance technicians, pipefitters, and general tradespeople across a wide range of structural and equipment-mounting applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in heavy equipment assembly, structural steel connections, machinery mounting, and industrial maintenance repairs where Grade 8 strength is specified. The partial threading allows a smooth shank section between the bearing surface and the threaded engagement zone, which is important in applications requiring precise shear load distribution or clearance fit through one or more members before thread engagement begins.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance and visual identification as a high-strength fastener\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports accurate load transfer and clearance-fit installation\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fit and interchangeability\u003c\/li\u003e\n  \u003cli\u003eHex head drive accepts standard hex wrenches and impact sockets for efficient installation and removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC inch-series hex nuts, flat washers, and lock washers in bolted assemblies conforming to ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified tradespeople or maintenance technicians using standard hex wrenches, combination wrenches, or impact drivers fitted with the appropriate socket.
