It follows the Unified National Coarse (UNC) thread standard and is measured length-under-head. The 18-8 stainless steel construction provides solid corrosion resistance, making this fastener suitable for general mechanical assembly work in HVAC, plumbing, electrical panel, and equipment enclosure applications. Installation is straightforward with a standard flat-blade screwdriver. This fastener is sold in multiples of 25 units per order.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in a wide range of light-duty mechanical and structural fastening tasks. Common applications include securing control boards, mounting brackets, access panels, equipment enclosures, and junction boxes. The round head profile sits above the material surface, making it a practical choice where a low-profile dome head is acceptable and countersinking is not required. Trade professionals in HVAC, electrical, and plumbing work regularly stock this size for field repairs and equipment assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch length measured under head\u003c\/li\u003e\n  \u003cli\u003eRound head, slotted drive — installs with a standard flat-blade screwdriver\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no plating to flake or contaminate contact surfaces\u003c\/li\u003e\n  \u003cli\u003eNo washer included — bare fastener for flexible use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC machine screw suitable for use wherever a round head slotted fastener of this thread size and length is specified in mechanical, HVAC, electrical, or plumbing equipment assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a flat-blade screwdriver sized to the slot.
