This nut features a bright, uncoated finish and a right-hand thread. With a 5.5 mm width across flats and a 3.0 mm height, it is suited for compact fastening applications where corrosion resistance is a priority. Sold in a minimum order quantity of 200 pieces, these nuts meet the NFE 25407 fastener standard. Plumbers, HVAC technicians, electricians, and general trade professionals reach for Grade A2 stainless hardware when working in humid, corrosive, or wet environments where carbon steel hardware would degrade.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is appropriate for use in residential and light commercial mechanical, plumbing, and electrical assemblies where M3 metric threaded fasteners are specified. The M3 x 0.50 thread pitch is common in panel mounting, small equipment brackets, and instrumentation assemblies. The austenitic 18-8 alloy provides good resistance to oxidation and mild chemical exposure, making it a reliable choice for indoor and outdoor installations. The uncoated bright finish is compatible with standard stainless steel mating hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.50 metric right-hand thread for precise mating with standard M3 bolts and studs\u003c\/li\u003e\n  \u003cli\u003e18-8 austenitic stainless steel, Grade A2, for corrosion resistance without a surface coating\u003c\/li\u003e\n  \u003cli\u003e5.5 mm width across flats for use with standard metric wrenches and nut drivers\u003c\/li\u003e\n  \u003cli\u003e3.0 mm height provides a low-profile fastening footprint in tight assemblies\u003c\/li\u003e\n  \u003cli\u003eMeets NFE 25407 fastener standard\u003c\/li\u003e\n  \u003cli\u003eSold in multiples of 200, suitable for production, service fleet stocking, or bulk repair jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M3 x 0.50 metric threaded bolts, screws, and studs in assemblies requiring Grade A2 stainless steel hardware per NFE 25407.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard 5.5 mm metric wrench or nut driver. Verify thread engagement depth and ensure mating fastener threads are clean and free of debris before assembly. Avoid mixing stainless steel fasteners with dissimilar metals in highly conductive or electrochemically active environments to reduce galvanic corrosion risk. No special tools or trade licenses are required, but always follow the equipment manufacturer torque guidance for M3 fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3 x 0.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8 Austenitic Grade A2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 5.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: NFE 25407\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 200 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0013 pounds (per piece)\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: HHNX00300-200BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700009009458,"sku":"HHNX00300-200BX","price":12162.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a84a5d51ac668fa7c260f060cc68ef1a.jpg?v=1788384892","url":"https:\/\/voomisupply.com\/products\/value-collection-hhnx00300-200bx-m3-x-0-50-hex-nut-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
