Machined from brass with a nickel plated finish, this jam nut incorporates a silicone O-ring that compresses against the mating surface to prevent fluid or gas leakage at the joint. The nut follows a right-hand UNF thread standard at 1\/4-28 thread size, measures 7\/16 inches across the flats, and stands 7\/32 inches tall. It is well suited for plumbing, hydraulic, pneumatic, and instrumentation assemblies where a low-profile locking nut with sealing capability is required. Licensed trades and MRO technicians install these as part of precision fluid system builds and repairs.\u003c\/p\u003e\n\u003cp\u003eThis self sealing hex jam nut is used in residential and light commercial mechanical systems where threaded connections must resist loosening under vibration and maintain a leak-free seal. Common applications include instrumentation fittings, pneumatic tubing junctions, hydraulic manifolds, and plumbing supply line connections. The silicone O-ring provides sealing compatibility with a broad range of media. The nickel plated brass construction resists corrosion in moist or chemically active environments. This item is sold in a pack of five, making it practical for service calls, panel builds, or small-quantity bench stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated silicone O-ring provides a self sealing function without additional sealant tape or compound\u003c\/li\u003e\n  \u003cli\u003eBrass base material with nickel plated finish for corrosion resistance in wet or moderate-chemical environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF right-hand thread for precise engagement on fine-pitch threaded connections\u003c\/li\u003e\n  \u003cli\u003eLow-profile hex jam nut geometry at 7\/32 inches tall allows use in tight clearance locations\u003c\/li\u003e\n  \u003cli\u003e7\/16 inch width across flats fits standard open-end and combination wrenches\u003c\/li\u003e\n  \u003cli\u003eSold in a five-piece pack to support field service and bench stock needs\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 threaded assemblies using 1\/4-28 UNF right-hand thread specifications in brass or steel components requiring an integrated sealing nut.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by plumbers, pipefitters, HVAC technicians, and instrumentation mechanics working on fluid or pneumatic systems. Always depressurize and isolate the system before removing or installing sealing hardware. Use an appropriately sized open-end wrench on the 7\/16 inch flats and avoid over-torquing, which can damage the silicone O-ring and compromise the seal. Inspect the mating sealing surface for burrs or damage before installation to ensure proper O-ring contact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: Nickel Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Thickness\u003c\/strong\u003e: 1\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161727\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: 1\/4-28 AJ6MC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701073314098,"sku":"1\/4-28 AJ6MC","price":81.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3ba2bd384ff516fcbc32f70504a7568.jpg?v=1788397852","url":"https:\/\/voomisupply.com\/products\/value-collection-1-4-28-aj6mc-brass-hex-jam-nut-unf-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
