Manufactured from alloy steel with a black oxide finish, this screw delivers a hardness rating of 38 HRC and meets ANSI\/ASME B18.3 and ASTM F835 standards. It features a hex socket drive sized at 5\/32 inch and is fully threaded with a 3A thread fit class to UNRC standards. The 3\/4-inch length under head and 0.437-inch head diameter make it well suited for flush or near-flush installations in tight clearance assemblies. Licensed tradespeople and maintenance professionals install this fastener using a standard hex key or Allen driver.\u003c\/p\u003e\n\u003cp\u003eThis button socket cap screw is used in general mechanical assemblies, machine guarding, enclosures, and structural sub-assemblies where a domed, low-profile head is preferred over a flat or pan head. The right-hand thread and 3A fit class make it compatible with standard 1\/4-20 tapped holes and threaded inserts across a wide range of industrial and commercial applications. Its black oxide coating provides mild corrosion resistance and reduces light reflection in finished assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction with 38 HRC hardness for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and a matte appearance\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for use with standard Allen or hex key tools\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1\/4-20 UNC right-hand thread with 3A fit class\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eLow-profile button head at 0.132-inch head height suits tight clearance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC button socket cap screw compatible with any 1\/4-20 tapped hole or threaded insert conforming to UNRC thread standards in industrial, commercial, or mechanical assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 5\/32-inch hex key or Allen driver.
