Manufactured from alloy steel with a black oxide finish, this fully threaded fastener measures 7\/8 inches in length under the head and is driven by a 3\/16-inch hex socket. It meets ANSI\/ASME B18.3 and ASTM F835 standards, with a hardness rating of 36-43 HRC and a Class 3A thread fit. The low-profile button head reduces interference in tight clearance areas while maintaining high clamping strength. Licensed trades and mechanical contractors use this fastener wherever a flush or near-flush head profile is required with a high-strength alloy body.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in light and heavy mechanical assemblies, machine components, and structural connections where UNC threading and a button head profile are specified. The black oxide finish provides mild corrosion resistance in controlled interior environments. The fully threaded shank engages the full grip length of the fastener, making it appropriate for thinner material applications. This SKU is sold in a package quantity of 1 unit with a minimum order quantity of 50 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC fully threaded alloy steel construction with 36-43 HRC hardness\u003c\/li\u003e\n  \u003cli\u003e7\/8 inches length under head with a low-profile button head measuring 0.166 inches in height\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance in interior service environments\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eClass 3A thread fit for consistent, precise thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC button socket cap screw for use in any application calling for a 5\/16-18 thread, 7\/8-inch grip length, and button head profile per ANSI\/ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/16-inch hex key or hex socket bit driver.
