It features a hex socket drive sized at 5\/32 inch and is manufactured from alloy steel with a black oxide finish. Fully threaded with a right-hand UNRC thread form and a 3A fit class, this fastener meets ANSI\/ASME B18.3 and ASTM F835 standards. The button head profile offers a low-profile, domed appearance with a 0.437 inch head diameter and 0.132 inch head height. A Rockwell hardness rating of 38 HRC ensures reliable strength in demanding mechanical assemblies. Installed by maintenance technicians, millwrights, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for general mechanical assemblies where a low-profile head is required to clear adjacent components or provide a flush-style appearance. Common applications include machine guards, brackets, enclosures, and equipment panels in industrial, commercial, and light manufacturing environments. The black oxide finish provides mild corrosion resistance and a uniform appearance. It is sold individually but requires a minimum order quantity of 100 pieces, making it appropriate for maintenance shops, MRO stocking, and production line use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread with 3A fit class for consistent thread engagement\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch length under head, fully threaded\u003c\/li\u003e\n  \u003cli\u003eLow-profile button head at 0.437 inch diameter and 0.132 inch height\u003c\/li\u003e\n  \u003cli\u003e5\/32 inch hex socket drive for standard L-key or socket bit installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated at 38 HRC hardness\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and MRO replacement fastener for 1\/4-20 UNC tapped holes requiring a button head socket cap screw per ANSI\/ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 5\/32 inch hex key or socket bit driver.
