It features a 5\/16-18 UNC thread size with a 1-1\/4 inch length under head, machined from alloy steel grade 4037 and finished with a yellow cadmium plating for corrosion resistance. Drive interface is a 1\/4 inch hex socket, compatible with standard Allen keys and hex bit drivers. This screw conforms to ASME B18.3, making it suitable for applications requiring dimensional traceability to a recognized fastener standard. Maintenance technicians, millwrights, and general tradespeople use this fastener in equipment assembly and repair work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in moderate-strength clamping and fastening applications across industrial machinery, HVAC equipment frames, pump assemblies, and similar mechanical systems. The alloy steel construction handles higher tensile demands than standard carbon steel fasteners. Yellow cadmium plating provides a degree of corrosion protection in environments with exposure to moisture or mild chemicals. It is sold individually but requires a minimum order of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC fully threaded shank for consistent thread engagement\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel grade 4037 provides higher tensile strength than standard low-carbon steel\u003c\/li\u003e\n  \u003cli\u003eYellow cadmium plating offers corrosion resistance in exposed or moist environments\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex socket drive accepts standard Allen wrenches and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 fastener standard for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service hex socket cap screw for any application specifying a 5\/16-18 UNC fully threaded socket head cap screw per ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/4 inch hex key or hex bit driver. Ensure mating threads are clean and free of debris before driving. Power down or de-energize any equipment before accessing fastener locations inside live assemblies.
