Manufactured from alloy steel with a black oxide finish, this screw offers solid corrosion resistance and reduced light reflection in low-visibility environments. It carries a 4-40 UNC thread size, measures 7\/16 inches under the head, and is fully threaded along its entire length. The 3\/32 inch hex drive requires an Allen key or hex bit driver for installation. This fastener suits mechanical assemblies, instrument panels, electronics enclosures, and light-duty machine work where small-diameter threaded fasteners are called for.\u003c\/p\u003e\u003cp\u003eThis screw is suited for residential, commercial, and industrial assembly applications where compact, high-strength fastening is required. Fully threaded construction provides maximum thread engagement across the full shaft length, making it appropriate for thin-material applications such as sheet metal brackets, instrument housings, and precision equipment. It is commonly installed by machinists, electronics technicians, and mechanical assemblers working with small-form-factor components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread size for standard small-diameter fastening\u003c\/li\u003e\n\u003cli\u003e7\/16 inch length under head for shallow and thin-material installations\u003c\/li\u003e\n\u003cli\u003eFully threaded for maximum thread engagement along entire shaft\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for strength in demanding mechanical environments\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides moderate corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 UNC hex socket cap screw suitable for use in any application requiring ASME\/ANSI B18.3 compliant small-diameter alloy steel fasteners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 3\/32 inch hex key or Allen driver; using an improperly sized driver risks stripping the socket. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread-locking compound if vibration resistance is required by the assembly specification.
