The screw features a 1\/4-28 UNF thread and measures 1 inch in length under the head, driven by a 5\/32-inch hex socket. Manufactured from alloy steel with a black oxide coating, the fastener delivers corrosion resistance and a clean, uniform finish. Hardness is rated at 36-43 HRC, and the thread fit meets Class 3A tolerances for close-tolerance assemblies. Each pack contains 50 screws. Licensed HVAC techs, machinists, and general trade professionals use this fastener for equipment panels, brackets, and assemblies where a flush or recessed appearance is required.\u003c\/p\u003e\n\u003cp\u003eThis button head cap screw is suited for light to medium-duty fastening in equipment manufacturing, HVAC equipment assembly, panel mounting, and general mechanical fabrication. The black oxide finish reduces light reflection and provides mild corrosion protection in dry to low-humidity environments. The fully threaded shank and UNF thread standard make it compatible with tapped holes requiring fine thread engagement. The 50-piece pack quantity is appropriate for service inventory, production runs, or field kit restocking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF thread, Class 3A fit for tight-tolerance engagement\u003c\/li\u003e\n  \u003cli\u003e1-inch length under the head, fully threaded shank\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for standard Allen key or bit driver\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated 36-43 HRC\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for corrosion resistance and low-glare finish\u003c\/li\u003e\n  \u003cli\u003eConforms to 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 a standard 1\/4-28 UNF button socket cap screw suitable for tapped holes conforming to ANSI\/ASME B18.3 specifications in equipment panels, brackets, and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 5\/32-inch hex key or socket bit driver. Ensure the tapped hole is clean and free of debris before threading to avoid cross-threading.
