The round head profile provides a low-profile, dome-shaped bearing surface suitable for through-hole and clearance-fit applications. The slotted drive accepts a standard flat-blade screwdriver, making it a reliable choice in controlled-torque situations where cam-out risk is low. Machined from bright, uncoated brass, this screw offers natural corrosion resistance and electrical conductivity, properties that make it a practical selection in instrumentation, terminal boards, and enclosure work. The fastener measures 3\/8 inches in length under the head on a 2-56 thread pitch.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in residential and commercial electrical panels, HVAC control boards, instrumentation housings, and light-gauge sheet-metal enclosures where a small-diameter brass fastener is specified. It is well suited to applications where ferrous fasteners are undesirable due to conductivity or corrosion concerns. Electricians, HVAC technicians, and instrument technicians regularly use fasteners in this size range when servicing terminal strips, grounding lugs, and low-voltage control wiring assemblies. The inch-measurement system and UNC thread form are standard across North American trade equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-56 UNC thread form — standard inch-series coarse thread for reliable engagement in tapped brass or aluminum components\u003c\/li\u003e\n  \u003cli\u003eRound head profile provides a wide bearing surface with a clean, low-profile appearance\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accommodates flat-blade screwdrivers for straightforward installation and removal\u003c\/li\u003e\n  \u003cli\u003eBrass construction offers inherent corrosion resistance and electrical conductivity\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no plating to interfere with electrical contact surfaces\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch length under head suits thin panel and circuit board fastening scenarios\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for any application specifying a 2-56 UNC round-head slotted brass machine screw with a 3\/8-inch length under the head and no washer face.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDe-energize all circuits and discharge any stored energy before servicing panels or control boards where these screws are used. A properly sized flat-blade screwdriver matched to the slot width reduces the risk of head damage and cam-out on small-diameter fasteners. Do not overtighten into tapped plastic or soft-metal bosses, as the 2-56 thread is fine enough to strip under excessive torque. NEC guidelines apply when fasteners are used in electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R63088446\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698455478578,"sku":"R63088446","price":969.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9367ba95a94cfc3c247cd9fb12c7c38.jpg?v=1788363118","url":"https:\/\/voomisupply.com\/products\/value-collection-r63088446-machine-screw-2-56-x-3-8-in-round-head","provider":"Voomi Supply","version":"1.0","type":"link"}
