Manufactured from alloy steel with a black oxide coating, this fastener delivers corrosion resistance and a clean, finished appearance in assemblies where head clearance is limited. The screw features a 3\/8-16 UNC thread with a right-hand thread direction and a 7\/32 inch hex socket drive. It measures 3-1\/2 inches under the head and is fully threaded along its length. Hardness is rated at 36-43 HRC, meeting ANSI\/ASME B18.3 and ASTM F835 standards. This fastener is installed by machinists, millwrights, and maintenance technicians across industrial and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for machine assemblies, fixtures, enclosures, and structural applications where a flush or recessed button head profile is required. The black oxide finish makes it a common choice in applications where contrast or low reflectivity is preferred. The fully threaded design allows engagement along the full length of the fastener, offering flexibility in clamping range. It is appropriate for use in both light industrial and precision mechanical applications across manufacturing and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile provides low clearance and a smooth finished appearance in assemblies\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 36-43 HRC hardness for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating adds corrosion resistance and reduces surface reflectivity\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/8-16 UNC right-hand thread for maximum engagement flexibility\u003c\/li\u003e\n  \u003cli\u003e7\/32 inch hex socket drive for standard Allen key or hex bit installation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC button socket cap screw per ANSI\/ASME B18.3 and ASTM F835, compatible with any tapped hole or threaded insert conforming to 3\/8-16 UNC Class 3A thread specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 7\/32 inch hex key or socket bit driver.
