It can become swollen over time due to moisture and corrosion. Swollen lug nuts can become difficult to remove using standard tools. You might not be able to change a flat tire if you have a swollen lug nut, and that&rsquo;s a situation you don&rsquo;t ever want to find yourself in.<\/p>\n\n\n\n<p>Find out about the dangers of swollen lug nuts and why you should replace them as soon as possible.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does a Swollen Lug Nut Look Like?<\/h2>\n\n\n\n<p>Two-piece lug nuts are nice and shiny because they&rsquo;re made from two kinds of metal. Steel is used to make the lug nut. Then a chrome sheet metal covering is added to make it shine. Rust can form in between the two layers of dissimilar metals over time, causing them to expand and warp.<\/p>\n\n\n\n<p>The lug nut on the left is an example of a normal lug nut, while the one on the right is an example of a swollen lug nut. Swollen lug nuts tend to look rusty, warped, or scuffed from being taken on and off.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/normal-and-swollen-lug-nut-1-1024x683.png\" alt=\"normal and swollen lug nu\" class=\"wp-image-70539\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/normal-and-swollen-lug-nut-1-1024x683.png 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/normal-and-swollen-lug-nut-1-300x200.png 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/normal-and-swollen-lug-nut-1-768x512.png 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/normal-and-swollen-lug-nut-1-1536x1024.png 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/normal-and-swollen-lug-nut-1.png 2048w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/normal-and-swollen-lug-nut-1-600x400.png 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/normal-and-swollen-lug-nut-1-150x100.png 150w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Swollen lug nuts tend to look rusty, warped, or scuffed from being taken on and off.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Causes Lug Nuts to Swell?<\/h2>\n\n\n\n<p>Steel can corrode and push against the nut&rsquo;s chrome cover, causing it to enlarge. This can happen naturally through galvanic corrosion. When two dissimilar metals are exposed to one common electrolyte, one of the metals can corrode. <strong>Force can also accelerate the swelling of a lug nut<\/strong>. Removing lug nuts with cheap impact sockets can cause the top chrome layer to loosen and create an opening for water, salt, and corrosion. This problem is prevalent in some <a href=\"https:\/\/www.carparts.com\/jeep\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Jeep\">Jeep<\/a>, <a href=\"https:\/\/www.carparts.com\/toyota\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Toyota\">Toyota<\/a>, <a href=\"https:\/\/www.carparts.com\/ford\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Ford\">Ford<\/a>, <a href=\"https:\/\/www.carparts.com\/chrysler\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Chrysler\">Chrysler<\/a>, and <a href=\"https:\/\/www.carparts.com\/dodge\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Dodge\">Dodge<\/a> models.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Are Swollen Lug Nuts Dangerous?<\/h2>\n\n\n\n<p>As an example, a twenty-one-millimeter lug nut can grow to twenty-two millimeters when it swells.
