Check nuts, also called jam nuts or lock nuts, are threaded against a primary nut or fitting to prevent loosening under vibration or cyclic load. This nut features an uncoated stainless steel finish, providing natural corrosion resistance without any applied coating. The knurled round head allows for finger-tightening or light tool engagement. With an overall height of 0.25 inches, a head diameter of 0.875 inches, and a base diameter of 0.625 inches, this nut suits installations where a low-profile locking fastener is required. It is used by HVAC technicians, plumbers, electricians, and general trade professionals in equipment assembly and mechanical securing applications.\u003c\/p\u003e\u003cp\u003eThis check nut is suited for light industrial, commercial, and residential trade applications where stainless steel corrosion resistance is required. Common installation scenarios include panel assembly, pipe fitting lockdown, valve packing glands, and equipment mounting. The 1\/4-20 UNC thread standard is one of the most widely used coarse-thread sizes in North American trade work, making this nut compatible with a broad range of threaded rods, studs, and bolts in that size. It is sold individually with a minimum order quantity of one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC coarse thread for broad compatibility with standard threaded fasteners\u003c\/li\u003e\n\u003cli\u003eStainless steel construction provides inherent corrosion resistance without a coating\u003c\/li\u003e\n\u003cli\u003eRound knurled head allows hand-tightening and easy grip during installation\u003c\/li\u003e\n\u003cli\u003eLow-profile design: 0.25 inches overall height fits tight clearance applications\u003c\/li\u003e\n\u003cli\u003eUncoated finish eliminates coating thickness variability in precision fits\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.05 pounds per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fastener for 1\/4-20 UNC threaded assemblies requiring a round knurled check nut in stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCheck nuts are installed by a licensed or skilled tradesperson and should be threaded onto the fastener by hand first, then snugged against the primary nut using an appropriate wrench or nut driver. Always ensure threads are clean and free of debris before installation. Power down or de-energize any equipment before accessing fastener locations inside electrical enclosures or mechanical panels. Follow applicable NEC, IPC, or IFGC guidelines as relevant to the system being serviced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Check Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Round Knurled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KN-25SS-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51696331129138,"sku":"KN-25SS-G","price":23.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab2a03202c28c3f2f455ce20e53d7d8e.jpg?v=1788341564","url":"https:\/\/voomisupply.com\/products\/gibraltar-kn-25ss-g-check-nut-1-4-20-unc-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
