Conforming to DIN 934, this nut features a right-hand thread with a 6H thread fit class, making it suitable for precision metric fastener assemblies. At 60 mm across the flats and 31 mm in height, it is sized for heavy-duty bolting applications where corrosion resistance is critical. Plumbers, pipefitters, marine contractors, and structural fabricators working with stainless fastener systems are the primary installers of this hardware.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is intended for use in corrosive environments where Grade 316 stainless steel provides superior resistance to chlorides, acids, and oxidizing agents compared to standard 304-grade hardware. Typical applications include marine structures, chemical processing equipment, food-service installations, and coastal plumbing systems. The M39 x 4 coarse-thread profile and DIN 934 standard make it compatible with metric threaded rod, bolts, and studs of the same pitch and thread class in industrial and commercial assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 Austenitic Grade A4 stainless steel for high corrosion resistance in chloride and acidic environments\u003c\/li\u003e\n  \u003cli\u003eDIN 934 fastener standard ensures dimensional interchangeability with metric hardware\u003c\/li\u003e\n  \u003cli\u003eM39 x 4 right-hand thread with 6H fit class for accurate, controlled thread engagement\u003c\/li\u003e\n  \u003cli\u003e60 mm across flats allows use with standard heavy-hex wrenching tools\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains base material properties without added coating thickness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a metric-standard replacement or new-installation hex nut for M39 x 4 threaded fastener systems conforming to DIN 934 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with metric fastener systems and applicable torque standards for the specific assembly. Ensure the mating bolt or threaded rod is also Grade 316 stainless or a compatible alloy to prevent galvanic corrosion. Lubricate threads with an anti-seize compound rated for stainless steel to reduce galling during tightening. Never use a nut that shows signs of thread damage, distortion, or contamination before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M39 x 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 934\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: 316 Austenitic Grade A4\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: 60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 31 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0011 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HN4XX03900-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694092615986,"sku":"HN4XX03900-005BX","price":168.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99bdd0c85e236192219dc22ec65997d7.jpg?v=1788320134","url":"https:\/\/voomisupply.com\/products\/value-collection-hn4xx03900-005bx-m39x4-hex-nut-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
