It features a 5\/16-18 UNC thread and measures 4 inches in length under the head. Drive engagement is through a 1\/4 inch internal hex socket, requiring an Allen wrench or hex bit driver. Constructed from 18-8 stainless steel, this fastener offers corrosion resistance suitable for wet, outdoor, or chemically exposed environments. It is installed by maintenance technicians, millwrights, pipefitters, and general mechanical tradespeople.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in equipment assemblies, enclosures, brackets, and structural connections where a flush or low-profile head and high corrosion resistance are required. The 5\/16-18 UNC coarse thread pattern provides reliable engagement in standard tapped holes and threaded inserts across a wide range of industrial and commercial equipment. The 18-8 stainless steel alloy makes it appropriate for food service, marine-adjacent, and outdoor installations where carbon steel fasteners would corrode.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for standard tapped-hole compatibility\u003c\/li\u003e\n  \u003cli\u003e4 inch length under head for deep-reach fastening applications\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch internal hex drive for Allen wrench or hex bit engagement\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n  \u003cli\u003eSocket cap head profile keeps hardware low-profile and recessed in counterbored applications\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 tapped hole or threaded insert accepting 5\/16-18 coarse thread fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires an Allen wrench or hex bit driver sized at 1\/4 inch. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or anti-seize compound when installing into dissimilar metals to prevent galling on stainless threads.
