A nylon lock nut, often referred to as a nyloc nut, is a prevailing torque type of locknut that features a nylon collar (or insert) at its top. When the nut is screwed onto a bolt, the internal threads engage with the bolt’s threads. As the bolt reaches the nylon portion, it forces the nylon to expand, creating a strong frictional fit and a prevailing torque that resists loosening under vibration and torque. This makes it a highly effective self-locking fastener.<\/p>\n
The primary materials used for the metal body of nylon lock nuts are:<\/p>\n
Carbon Steel:<\/strong>\u00a0The most common and cost-effective material.<\/p>\n<\/li>\n Stainless Steel:<\/strong>\u00a0Offers excellent corrosion resistance (e.g., Grades 304 and 316).<\/p>\n<\/li>\n Brass:<\/strong>\u00a0Provides good corrosion resistance and is often used for its aesthetic appeal in decorative applications.<\/p>\n<\/li>\n Aluminum:<\/strong>\u00a0Valued for its light weight and corrosion resistance.<\/p>\n<\/li>\n<\/ul>\n The locking element is consistently a durable, resilient nylon (polyamide) ring.<\/p>\n To enhance corrosion resistance and appearance, the metal body of the nut often receives a surface treatment. Common treatments include:<\/p>\n Zinc Plating:<\/strong>\u00a0A very common finish, often with a clear (blue-bright) or yellow (zinc dichromate) color.<\/p>\n<\/li>\n Hot-Dip Galvanizing:<\/strong>\u00a0Provides a thick, rugged coating for harsh environments.<\/p>\n<\/li>\n Nickel Plating:<\/strong>\u00a0Offers a hard, corrosion-resistant surface with a shiny, silver appearance.<\/p>\n<\/li>\n Phosphate Coating:<\/strong>\u00a0Mainly used as a base for paint or oil, providing some corrosion resistance.<\/p>\n<\/li>\n<\/ul>\n Nylon lock nuts are manufactured in a wide range of specifications to meet various industrial standards and requirements.<\/p>\n Thread Sizes:<\/strong>\u00a0Available in metric (e.g., M3, M4, M5, up to M20 and beyond) and imperial (e.g., #4-40, 1\/4″-20, 1\/2″-13) thread sizes.<\/p>\n<\/li>\n Standards:<\/strong>\u00a0Common standards include DIN 985 (International Metric), ISO 7040, and IFI 100\/107.<\/p>\n<\/li>\n Grades\/Classes:<\/strong>\u00a0For steel nuts, common strength grades are 5, 8, 9, 10, and 12, indicating the nut’s proof load and material strength.<\/p>\n<\/li>\n<\/ul>\n Due to their reliable self-locking ability, nylon lock nuts are used across numerous industries:<\/p>\n Automotive:<\/strong>\u00a0In engines, transmissions, chassis, and body panels to withstand constant vibration.<\/p>\n<\/li>\n Aerospace:<\/strong>\u00a0In non-critical structural components and interior panels.<\/p>\n<\/li>\n Machinery and Equipment:<\/strong>\u00a0To secure parts on industrial machinery, conveyor systems, and agricultural equipment.<\/p>\n<\/li>\n Electronics:<\/strong>\u00a0For fastening components in appliances and electronic enclosures.<\/p>\n<\/li>\n Furniture Assembly:<\/strong>\u00a0To prevent joints from coming loose over time.<\/p>\n<\/li>\n Construction and Infrastructure:<\/strong>\u00a0In steel structures, scaffolding, and HVAC systems.<\/p>\n<\/li>\n<\/ul>\n An industrial robotic arm on an assembly line performs rapid, repetitive movements thousands of times a day, generating significant vibration. A critical pivot joint, which must maintain precise alignment, is fastened using a high-grade (Class 10) stainless steel nylon lock nut.<\/p>\n The nut is threaded onto a bolt that connects two sections of the arm. As the bolt tightens against the nylon insert, the resulting frictional lock ensures the joint remains securely fastened. This prevents any loosening that could lead to misalignment, reduced precision, or catastrophic failure. The use of the nyloc nut guarantees operational reliability, minimizes downtime for maintenance, and enhances the overall safety of the manufacturing cell.<\/p>","protected":false},"excerpt":{"rendered":" Colorful Aluminum Nylon Lock Nut Color Anodizing Hex Flange Nylon Insert Lock Nut<\/p>","protected":false},"featured_media":4118,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[34],"product_tag":[2867,2856,2866,2865,2864,950,134,951,133,2050,2049,1022,1021,2862,2858,2863,1402,132,1403,135,2855,2859,2860,2861,2857,1924,2869,2868,1404,136],"class_list":{"0":"post-4117","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-machined-nuts","7":"product_tag-1-2-nylon-lock-nuts","8":"product_tag-1-4-20-nylon-lock-nut","9":"product_tag-10-24-nylon-lock-nuts","10":"product_tag-4-40-nylon-lock-nuts","11":"product_tag-5-8-nylon-lock-nuts","12":"product_tag-cnc-machined-nut","13":"product_tag-cnc-machined-nuts","14":"product_tag-cnc-machining-nut","15":"product_tag-cnc-machining-nuts","16":"product_tag-cnc-nut","17":"product_tag-cnc-nuts","18":"product_tag-custom-nut","19":"product_tag-custom-nuts","20":"product_tag-m10-nylon-lock-nuts","21":"product_tag-m8-nylon-lock-nut","22":"product_tag-m8-nylon-lock-nuts","23":"product_tag-machined-nut","24":"product_tag-machined-nuts","25":"product_tag-machining-nut","26":"product_tag-machining-nuts","27":"product_tag-nylon-lock-nut","28":"product_tag-nylon-lock-nut-m10","29":"product_tag-nylon-lock-nut-m12","30":"product_tag-nylon-lock-nut-m3","31":"product_tag-nylon-lock-nut-m6","32":"product_tag-nylon-lock-nuts","33":"product_tag-nylon-lock-nuts-m6","34":"product_tag-nylon-lock-nuts-m8","35":"product_tag-special-nut","36":"product_tag-special-nuts","38":"first","39":"instock","40":"shipping-taxable","41":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/machinedwasher.com\/nl\/wp-json\/wp\/v2\/product\/4117","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/machinedwasher.com\/nl\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/machinedwasher.com\/nl\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/machinedwasher.com\/nl\/wp-json\/wp\/v2\/comments?post=4117"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/machinedwasher.com\/nl\/wp-json\/wp\/v2\/media\/4118"}],"wp:attachment":[{"href":"https:\/\/machinedwasher.com\/nl\/wp-json\/wp\/v2\/media?parent=4117"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/machinedwasher.com\/nl\/wp-json\/wp\/v2\/product_brand?post=4117"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/machinedwasher.com\/nl\/wp-json\/wp\/v2\/product_cat?post=4117"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/machinedwasher.com\/nl\/wp-json\/wp\/v2\/product_tag?post=4117"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
