It measures 4-1\/2 inches in length under the head and is designed for general mechanical fastening applications where a low-profile round head and standard slotted drive are required. The zinc finish provides basic corrosion resistance. This screw uses unified national coarse thread at 1\/4-20 and is sold in minimum order quantities of 100 pieces per purchase, with one screw per package unit. Typical installers include maintenance technicians, electricians, and mechanical trades working on panel assemblies, enclosures, and structural components.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is suited for residential and commercial mechanical, electrical, and structural assembly work. The 1\/4-20 UNC thread is one of the most common inch-series fastener standards in North American trade applications. The round head profile keeps a low footprint on the work surface, and the slotted drive accommodates standard flat-blade screwdrivers. It is appropriate for use in sheet metal assemblies, equipment panels, junction boxes, support brackets, and similar trade installations where an alloy steel fastener with zinc protection is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread — standard inch-series coarse thread for broad tool and hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch length under head for deeper through-fastening applications\u003c\/li\u003e\n  \u003cli\u003eRound head profile with slotted drive for flat-blade screwdriver installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for strength in mechanical fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc finish for basic corrosion resistance in indoor and protected environments\u003c\/li\u003e\n  \u003cli\u003eNo washer — fastens directly against the work surface without an integrated washer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC inch-series machine screw compatible with any tapped hole, threaded insert, or nut machined to 1\/4-20 UNC specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical, electrical, or general maintenance trades using a flat-blade screwdriver or slotted bit driver sized for a 1\/4-20 head.
