The nut features a right-hand thread direction and an uncoated finish. It measures 0.25 inches across the flats and stands 0.09375 inches (3\/32 inches) high. Brass construction provides natural corrosion resistance and good electrical conductivity, making this nut a common choice in electrical panels, instrumentation enclosures, and plumbing fixture assemblies where galling with steel fasteners is a concern. These are sold individually per package, with a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is suited for use in residential and light commercial applications requiring a 4-40 UNC thread engagement. Typical install scenarios include control board standoffs, instrument panel assembly, low-voltage electrical enclosures, and small-diameter plumbing or HVAC component mounting where a brass fastener is specified. Installers in electrical, HVAC, and plumbing trades commonly stock 4-40 hardware for terminal block and sensor bracket work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread standard with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eBrass material offers corrosion resistance and non-sparking properties\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no plating to chip or delaminate in service\u003c\/li\u003e\n  \u003cli\u003eCompact profile: 0.25 inches across flats, 3\/32 inches high\u003c\/li\u003e\n  \u003cli\u003eSold in multiples of 100 — suitable for bench stock and bulk fastener inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4-40 UNC machine screws in standard hex nut applications across electrical, HVAC, and instrumentation assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a wrench or nut driver sized for a 0.25-inch hex flat. Always ensure the mating screw thread standard matches 4-40 UNC before assembly to avoid cross-threading. Brass is softer than steel — do not overtighten, as the threads can strip under excessive torque. Verify that brass is appropriate for the service environment, particularly where dissimilar-metal corrosion could be a concern.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcross Flats\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.09375 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 91601\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695517991218,"sku":"91601","price":2743.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a82b193b8581e96b5e27bcd9a6c411a9.jpg?v=1788336037","url":"https:\/\/voomisupply.com\/products\/value-collection-91601-4-40-unc-brass-hex-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
