This screw features a 4-40 UNC thread, a 1-inch length under head, and a 3\/32-inch hex drive. It is partially threaded and manufactured from alloy steel with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. Licensed machinists, millwrights, and mechanical assemblers typically specify this fastener where a low-profile, high-strength cap screw is required. It conforms to ASME B18.3 and ASTM A574 standards, confirming tensile strength and dimensional compliance for critical fastener applications.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for light-duty machine components, instrument enclosures, electrical panel assemblies, and jig-and-fixture work where a small-diameter socket head cap screw is required. The 4-40 UNC thread is a common size in precision equipment, control panel hardware, and electronic chassis assemblies. The black oxide finish makes it a practical choice in low-moisture indoor environments. Sold individually with a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread size for precision small-diameter fastening applications\u003c\/li\u003e\n\u003cli\u003e1-inch length under head with partial threading for controlled engagement depth\u003c\/li\u003e\n\u003cli\u003e3\/32-inch hex drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 tensile strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating reduces surface reflectivity and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.3 dimensional standard for socket head cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for assemblies requiring a 4-40 UNC hex socket cap screw with a 1-inch length under head and a 3\/32-inch drive, conforming to ASME B18.3 and ASTM A574.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a calibrated 3\/32-inch hex key or socket bit driver.
