{"product_id":"aerotight-nut-stainless-steel-a4","title":"Aerotight Nut Stainless Steel A4","description":"\u003cp data-path-to-node=\"15\"\u003eWhen structural integrity and safety are non-negotiable, thread failure due to vibration or environmental degradation is a risk you cannot afford. The Aerotight Nut Stainless Steel A4 offers an engineered solution designed to perform reliably under the most demanding conditions. Unlike standard hex nuts that require external locking washers or chemical thread-lockers, the Aerotight nut integrates its locking mechanism directly into the body of the fastener itself.\u003c\/p\u003e\n\u003cp data-path-to-node=\"16\"\u003eThe unique construction features two slotted cantilevered sections at the top of the nut. During installation on a male thread, these sections deflect slightly outward, exerting a consistent radial force against the mating threads. This friction lock holds the fastener firmly in position, preventing back-off caused by continuous vibration, thermal expansion, or dynamic stress loads. Because the locking action relies entirely on metal deflection rather than an insert, the nut remains effective in high-temperature environments that would cause standard nylon-insert lock nuts (Nyloc) to melt or degrade.\u003c\/p\u003e\n\u003cp data-path-to-node=\"17\"\u003eForged from A4 grade (316) stainless steel, this fastener is built specifically to withstand aggressive atmosphere types. A4 stainless steel contains molybdenum, which significantly enhances resistance to pitting, crevice corrosion, and chloride exposure compared to standard A2 stainless steel. This makes it an ideal choice for marine hardware, boatbuilding, architectural installations in coastal regions, wastewater treatment plants, and processing equipment exposed to harsh industrial chemicals.\u003c\/p\u003e\n\u003cp data-path-to-node=\"18\"\u003eFurthermore, the Aerotight design offers long-term maintenance advantages. The all-metal construction is re-usable, maintaining its friction-locking torque through repeated assemblies and teardowns. Because it does not rely on non-metallic elements that can harden or shear, maintenance teams can confidently service equipment without needing to replace the nut after every disassembly cycle. Streamline your inventory, reduce assembly times, and secure your mechanical installations with a dependable, premium-grade locking fastener built to last.\u003c\/p\u003e","brand":"Electro South West Ltd","offers":[{"title":"M3","offer_id":55701924020600,"sku":"SSNUTM3AEROA4","price":1.11,"currency_code":"GBP","in_stock":true},{"title":"M4","offer_id":55701924053368,"sku":"SSNUTM4AEROA4","price":0.99,"currency_code":"GBP","in_stock":true},{"title":"M5","offer_id":55701924086136,"sku":"SSNUTM5AEROA4","price":1.24,"currency_code":"GBP","in_stock":true},{"title":"M6","offer_id":55701924118904,"sku":"SSNUTM6AEROA4","price":1.36,"currency_code":"GBP","in_stock":false},{"title":"M8","offer_id":55701924151672,"sku":"SSNUTM8AEROA4","price":5.23,"currency_code":"GBP","in_stock":false},{"title":"M10","offer_id":55701924184440,"sku":"SSNUTM10AEROA4","price":7.69,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0802\/8658\/1049\/files\/ssaero_474e96dd-e6f2-4c9d-b7c3-e77b0a86d73a.jpg?v=1791973091","url":"https:\/\/www.electrosw.co.uk\/products\/aerotight-nut-stainless-steel-a4","provider":"Electro South West Ltd","version":"1.0","type":"link"}
