Sized at 4-40 UNC with a 3\/16-inch length under head and a 3\/32-inch hex drive, this screw is fully threaded from tip to head. Constructed from alloy steel with a black oxide finish coating, it meets ASME\/ANSI B18.3 and ASTM A574 standards. The black oxide coating provides moderate corrosion resistance and reduces light reflection. This part is sold individually but requires a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for light-duty mechanical assemblies, electronic enclosures, instrumentation panels, and precision machine components where a low-profile socket cap screw is required. The 4-40 UNC thread is a fine, small-diameter unified national coarse thread commonly used in tight-tolerance applications across industrial, electrical, and mechanical trades. Installation is performed with a 3\/32-inch hex key or Allen driver.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread size for precision small-fastener applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded body from tip to underside of head\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish coating for moderate corrosion resistance and reduced glare\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eRequires a 3\/32-inch hex key drive for installation and removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC hex socket cap screw for use in any application requiring an ASME\/ANSI B18.3 compliant fastener of this thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using a 3\/32-inch hex key or T-handle Allen driver. Ensure mating threads are clean and free of debris before driving. Do not overtorque alloy steel cap screws in soft or thin base materials, as thread stripping can occur.
