Threaded 5\/16-18 UNC, this fastener measures 3\/4 inches under the head and accepts a 1\/4-inch hex key drive. Constructed from 316 stainless steel, it offers strong corrosion resistance in wet, marine, and chemical-exposure environments. This screw is a standard choice for mechanical assemblies, equipment mounting, and structural connections across HVAC, plumbing, electrical, and general trade applications.\u003c\/p\u003e\n\u003cp\u003eThis fastener suits residential and commercial trade applications where a socket-drive cap screw is preferred over hex-head styles. The 5\/16-18 UNC thread is a common coarse-thread specification found in a wide range of equipment frames, brackets, panels, and enclosures. The 316 stainless steel construction makes it well suited for outdoor installations, humid mechanical rooms, poolside equipment, and any environment where mild-steel fasteners would corrode prematurely.\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\u003e3\/4-inch length under head for shallow-to-medium depth fastening\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch internal hex drive for use with standard Allen keys and hex bit sockets\u003c\/li\u003e\n  \u003cli\u003e316 stainless steel construction provides superior corrosion resistance over 304 grade\u003c\/li\u003e\n  \u003cli\u003eLow-profile socket cap head allows installation in space-constrained assemblies\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 for use in any application requiring this thread size and head style.
