It features an 82-degree flat head with a 3\/16-inch hex socket drive, allowing installation with a standard hex key. Manufactured from alloy steel with a black oxide finish, this screw delivers hardness in the 39-44 HRC range and meets the dimensional and performance requirements of ASME B18.3 and ASTM F835. The 5\/16-18 UNC thread is fully threaded along the 5\/8-inch overall length, conforming to Thread Fit Class 3A for precise engagement. It is typically installed by machinists, millwrights, and maintenance technicians in equipment assembly and structural fixture work.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in machine assemblies, jigs, fixtures, and structural components where a low-profile, flush-mount fastener is required. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it appropriate for tooling and precision equipment environments. The 5\/16-18 coarse thread pattern is widely used in general industrial and mechanical applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head profile for flush countersunk installation\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex socket drive for standard hex key use\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction with 39-44 HRC hardness rating\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion and glare resistance\u003c\/li\u003e\n\u003cli\u003eFully threaded 5\/16-18 UNC Thread Fit Class 3A along full 5\/8-inch length\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and aftermarket replacement flat socket cap screw for industrial machinery, tooling fixtures, and mechanical assemblies requiring a 5\/16-18 UNC countersunk fastener.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/16-inch hex key or hex bit driver.
