Manufactured from Grade 5 steel with a zinc-plated finish, this fastener measures 1-8 thread size with a 4-3\/4 inch length under head and follows the Unified National Coarse (UNC) thread standard. It conforms to ASME B18.2.1 and SAE J429 specifications, making it a recognized choice for applications where dimensional accuracy and material grade verification are required. Maintenance technicians, millwrights, and general contractors install these fasteners in a wide range of equipment and structural connections.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is suited for use in industrial, commercial, and residential mechanical assemblies where a Grade 5 UNC partially threaded fastener is specified. Partial threading provides a smooth shank section that resists shear forces and allows for cleaner load transfer across joint interfaces. Typical installations include equipment mounting, structural steel connections, and machinery frameworks where controlled clamping force is needed along with reliable corrosion resistance from the zinc-plated coating.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 and ASME B18.2.1 standards for tensile and proof load requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion resistance for indoor and light outdoor use\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear strength and load distribution in bolted joints\u003c\/li\u003e\n  \u003cli\u003eUNC thread form ensures broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-8 thread size and 4-3\/4 inch length under head suit medium-to-heavy structural fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stocking fastener for applications requiring a 1-8 UNC partially threaded hex head cap screw in Grade 5 steel with zinc plating, conforming to ASME B18.2.1 and SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard hex wrench or impact driver sized for the fastener head. Ensure mating threads in nuts or tapped holes are clean and free of debris before assembly.
