It measures 3 inches in length under the head and is manufactured from alloy steel with a zinc finish for basic corrosion resistance. This screw follows the inch measurement system and uses Unified National Coarse thread form, making it a standard fastener found in maintenance, equipment assembly, and fabrication work. Licensed tradespeople, maintenance technicians, and assembly workers typically stock this fastener for panel attachment, bracket mounting, and structural sub-assembly tasks.\u003c\/p\u003e\u003cp\u003eThis machine screw is suited for use in light to medium-duty fastening applications where a standard coarse-thread zinc-plated fastener is required. The round head profile sits above the work surface, providing a broad bearing area without countersinking. The slotted drive accepts a flat-blade screwdriver, making it accessible in the field with basic hand tools. It is commonly installed in HVAC equipment enclosures, electrical panel brackets, plumbing support hardware, and general mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard tapped holes and hex nuts\u003c\/li\u003e\n\u003cli\u003e3-inch length under head for applications requiring deeper thread engagement or fastening through thicker materials\u003c\/li\u003e\n\u003cli\u003eRound head profile provides a low-profile, finished appearance above the work surface\u003c\/li\u003e\n\u003cli\u003eSlotted drive works with standard flat-blade screwdrivers and bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction with zinc finish for strength and basic corrosion protection\u003c\/li\u003e\n\u003cli\u003eNo washer — installs directly against the mating surface\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for any application requiring a 1\/4-20 UNC round head slotted machine screw with a 3-inch length under head in inch-system hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a standard flat-blade screwdriver or slotted bit driver sized for a 1\/4-inch head.
