FAQ<\/strong><\/strong>s<\/h3>\n\n\n\n

Q1: Why is Dacromet coating superior for NFE 25-511 washers in outdoor use?<\/h3>
\n

Dacromet is not only more resistant to salt spray than zinc plating, but it also handles thermal cycling better. In outdoor electrical or structural applications, it prevents the “white rust” and base metal corrosion that lead to joint failure.<\/p>\n<\/div><\/div>\n\n\n\n

Q2: Does the coating thickness interfere with the serration’s ability to lock?<\/strong><\/h3>
\n

No. The Dacromet process results in a very thin, controlled layer (typically 5 to 10 microns). This ensures that the sharp serrated teeth remain fully functional and able to “bite” into the mating surfaces.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"

    \r\n \t
  • High-Performance Corrosion Defense<\/b>: The specialized Dacromet (Zinc Flake) coating provides up to 1000 hours of salt spray resistance, making it ideal for offshore, railway, and automotive infrastructure.<\/li>\r\n \t
  • Zero Hydrogen Embrittlement<\/b>: Utilizing a non-electrolytic coating process, these washers eliminate the risk of brittle failure, ensuring total structural safety for high-hardness spring steel.<\/li>\r\n \t
  • Tension-Based Vibration Locking<\/b>: The conical spring geometry maintains constant axial pressure, while radial serrations provide mechanical grip to prevent loosening under dynamic loads.<\/li>\r\n \t
  • Stable Friction Coefficient<\/b>: Dacromet engineering ensures a consistent torque-to-tension ratio, allowing for precise and repeatable preloading in critical industrial assemblies.<\/li>\r\n \t
  • Electrical Contact Optimization<\/b>: Precision-engineered serrations penetrate surface coatings to establish reliable grounding and electrical bonding in heavy-duty power applications.<\/li>\r\n<\/ul>","faqs_meta":null,"disable_global_faqs":false,"post_download_file":""},"_links":{"self":[{"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/wpkj_product\/2176","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/wpkj_product"}],"about":[{"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/types\/wpkj_product"}],"author":[{"embeddable":true,"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":2,"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/wpkj_product\/2176\/revisions"}],"predecessor-version":[{"id":2326,"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/wpkj_product\/2176\/revisions\/2326"}],"acf:attachment":[{"embeddable":true,"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/media\/2179"},{"embeddable":true,"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/media\/2178"},{"embeddable":true,"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/media\/2177"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/media\/2179"}],"wp:attachment":[{"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/media?parent=2176"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/product_cat?post=2176"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/xluig.com\/es\/wp-json\/wp\/v2\/product_tag?post=2176"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
