It features a 1\/4-28 UNF thread at 3\/8 inch length under head, a 5\/32 inch hex socket drive, and is manufactured from alloy steel with a black oxide finish. With a hardness rating of 36-43 HRC, this screw delivers reliable clamping force in demanding assemblies. It is fully threaded and conforms to ANSI\/ASME B18.3 and ASTM F835 standards. Machinists, maintenance technicians, and fabricators working with precision assemblies and tight clearances commonly specify this fastener type.\u003c\/p\u003e\u003cp\u003eThis button socket cap screw is suited for residential and commercial fabrication, machine assembly, tooling fixtures, and general industrial maintenance. The low-profile button head reduces interference in recessed or flush-mount installations where a standard hex cap screw head would protrude. The black oxide coating provides mild corrosion resistance and a consistent matte appearance. This screw is sold individually per package with a minimum order quantity of 100 pieces, making it appropriate for shop stock and production line replenishment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 UNF right-hand thread with Class 3A thread fit for precision engagement\u003c\/li\u003e\n\u003cli\u003e3\/8 inch length under head, fully threaded\u003c\/li\u003e\n\u003cli\u003e5\/32 inch hex socket drive for use with standard Allen or hex key tooling\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction, hardness 36-43 HRC for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating for mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNF button socket cap screw suitable for threaded assemblies requiring a 1\/4-28 thread form and a low-profile hex socket head per ANSI\/ASME B18.3 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a calibrated 5\/32 inch hex key or Allen driver to avoid rounding the socket drive.
