Unlike flat washers, this design provides superior resistance to loosening caused by vibrations, thermal expansion, or dynamic loads. The serrations &#8220;bite&#8221; into the mating surface and fastener, creating a locking effect, while the tapered shape adds spring tension to maintain clamping force.<\/p>\n<p class=\"ds-markdown-paragraph\">These washers are commonly used in high-stress applications where traditional flat or spring washers may fail. They come in two main types:<\/p>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong>External-toothed<\/strong>: Teeth on the outer edge for better grip on larger surfaces.<\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong>Internal-toothed<\/strong>: Teeth on the inner edge for enhanced locking on smaller fasteners<span class=\"ds-markdown-cite\">4<\/span><span class=\"ds-markdown-cite\">7<\/span>.<\/p>\n<\/li>\n<\/ul>\n<hr \/>\n<h2><strong>Materials of Tapered Serrated Lock Washers<\/strong><\/h2>\n<p class=\"ds-markdown-paragraph\">To suit various industrial needs, these washers are made from durable materials, including:<\/p>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong>Carbon Steel (e.g., 65Mn, 50#)<\/strong>\u00a0\u2013 High strength and cost-effective for general applications<span class=\"ds-markdown-cite\">8<\/span>.<\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong>Stainless Steel (e.g., 304, 316, 420)<\/strong>\u00a0\u2013 Excellent corrosion resistance for marine, chemical, and food industries<span class=\"ds-markdown-cite\">6<\/span><span class=\"ds-markdown-cite\">8<\/span>.<\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong>Alloy Steel<\/strong>\u00a0\u2013 Heat-treated for extreme stress resistance in heavy machinery.<\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong>Brass &amp;
