While correctly installing the rivet nut is vitally important to its success as a fastener, there\u2019s one more consideration you have to combat when it comes to rivet nut installation &#8212;\u00a0 corrosion.<\/p>\n<p>Corrosion protection for rivet nuts is vitally important when it comes to ensuring the rivet nut will be successful, and there are many ways to combat corrosion.<\/p>\n<p>First, what is corrosion? Corrosion is a surface oxidation process that appears, mainly, in two forms: white rust and red rust.<\/p>\n<p><strong>White Rust<\/strong> a white powder composed of zinc oxide, which eventually coats portions of a surface containing zinc such as the protective layer of zinc-based plating that coats many rivet nuts.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1412 size-full aligncenter\" src=\"https:\/\/dev.sherex.com\/wp-content\/uploads\/White-Rust.jpg\" alt=\"\" width=\"300\" height=\"168\" \/><\/p>\n<p>This corrosion does not directly harm the structural integrity of a piece, but makes the piece more vulnerable to a more compromising form of corrosion &#8212; red rust, referred to by many as simply \u201crust.\u201d<\/p>\n<p><strong>Red rust<\/strong> is an iron oxide that physically eats away at the base iron that composes your piece.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1413 size-thumbnail aligncenter\" src=\"https:\/\/dev.sherex.com\/wp-content\/uploads\/Red-Rust-300x200.jpg\" alt=\"\" width=\"300\" height=\"200\" srcset=\"https:\/\/dev.sherex.com\/wp-content\/uploads\/Red-Rust-300x200.jpg 300w, https:\/\/dev.sherex.com\/wp-content\/uploads\/Red-Rust-500x333.jpg 500w, https:\/\/dev.sherex.com\/wp-content\/uploads\/Red-Rust.jpg 768w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/p>\n<p>So how do you ensure optimal corrosion protection?<\/p>\n<p>Look for rivet nut offerings that are stress-tested with a \u201csalt-spray\u201d test, which subjects rivet nuts to heavy abrasion until rust appears. Rivet nuts coated in a <strong>zinc plate with trivalent chromate<\/strong>, which must, at minimum, withstand 96 hours in a salt-spray test before white rust appears with red rust not appearing for another 240 hours. Zinc plate with trivalent chromate comes in clear, yellow, or black options.<\/p>\n<p>For higher corrosion protection, <strong>zinc-nickel<\/strong> platings can achieve white-rust times of up to 144 hours minimum, as well as red-rust times of up to 1,200 hours.<\/p>\n<p>If you have rivet nuts that only come in a <strong>trivalent plating<\/strong>, a strip and re-plate operation is possible to obtain the plating that best suits you.<\/p>\n<p>The very best option when it comes to corrosion resistance is <strong>stainless steel<\/strong>. Stainless steel, though, can be difficult to install so make sure you have the proper tooling to ensure your stainless steel rivet nuts can be installed properly.<\/p>\n<p>If you have any questions regarding which plating or material solution fits your application best please <a href=\"\/en-gb\/contact-us\/\">contact us!<\/a> We are more than happy to give you the information necessary to make an informed decision.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By Frank Genovese, Applications Engineer, Sherex There\u2019s always peace of mind knowing that a correctly installed rivet nut is the end of your concerns.
