Sized at 5\/16-18 UNC with a 7\/8-inch length under head, this screw accepts a 1\/4-inch hex (Allen) drive. Constructed from 18-8 stainless steel, it provides corrosion resistance suitable for wet, outdoor, or chemically exposed environments. It meets ASME\/ANSI B18.3 and ASTM F837 standards. Each package contains 25 screws, making it practical for both single repairs and batch installations across a variety of trade applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in HVAC equipment panels, plumbing fixture mounting, electrical enclosures, and light structural assemblies where corrosion resistance and a clean socket-drive fastener are required. The 5\/16-18 UNC thread is a common coarse-thread size found across residential and commercial mechanical equipment. Installers typically reach for this size when securing brackets, access panels, and component mounting plates. The fully threaded shank maximizes thread engagement across thinner materials and shorter grip lengths.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch length under head suits thin-to-medium material stacks\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes clamping engagement\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and outdoor service\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for use with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F837 dimensional and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC hex socket cap screw suitable for any tapped hole or fastened joint calling for this thread size and drive type in trade mechanical and equipment-service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using a 1\/4-inch hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling, which is common with stainless fasteners.
