This process provides significantly better corrosion resistance than standard clear (white-blue) zinc plating, making it an excellent and cost-effective choice for applications with exposure to moisture, rain, and fluctuating temperatures. The distinctive gold\/yellow iridescent finish is a hallmark of this protective coating.<\/li>\n<li><strong>High-Strength Carbon Steel Core:<\/strong> The nut is manufactured from high-quality carbon steel and is available in a range of property classes, including <strong>Class 4.8<\/strong> for general use and high-strength classes like <strong>8.8, 10.9, and 12.9<\/strong> for demanding, load-bearing connections. This ensures you can select the appropriate strength for your specific structural or machinery requirements.<\/li>\n<li><strong>The DIN 577 Square Advantage:<\/strong> The primary feature of these nuts is their four-sided shape. This geometry provides a much larger gripping surface for a wrench, allowing for high-torque tightening. More importantly, it is ideal for being captured in a square channel or held against a flat surface, which prevents the nut from turning while a bolt is tightened. This makes assembly easier, especially in blind spots, and provides excellent resistance to loosening from vibration.<\/li>\n<li><strong>Standardized for Reliability:<\/strong> Manufactured in strict accordance with the DIN 577 standard, our square nuts guarantee uniform dimensions, thread profiles, and quality. This ensures a consistent, secure, and professional fit for every application, from mass production to one-off projects.<\/li>\n<\/ul>\n<h4><strong>Product Parameters<\/strong><\/h4>\n<p>The technical specifications for our Color Galvanized DIN 577 Square Nuts are detailed below.<\/p>\n<div class=\"MarkdownTable_tableContainer__2k5Kh\" tabindex=\"0\" role=\"region\">\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Specification<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Product Name<\/strong><\/td>\n<td>DIN 577 Square Nut<\/td>\n<\/tr>\n<tr>\n<td><strong>Standard<\/strong><\/td>\n<td>DIN 577<\/td>\n<\/tr>\n<tr>\n<td><strong>Material<\/strong><\/td>\n<td>Carbon Steel<\/td>\n<\/tr>\n<tr>\n<td><strong>Grade \/ Class<\/strong><\/td>\n<td>4.8, 8.8, 10.9, 12.9<\/td>\n<\/tr>\n<tr>\n<td><strong>Surface Treatment<\/strong><\/td>\n<td>Color Galvanized (Yellow Zinc Plated)<\/td>\n<\/tr>\n<tr>\n<td><strong>Size Range<\/strong><\/td>\n<td>M4 \u2013 M24<\/td>\n<\/tr>\n<tr>\n<td><strong>Brand Name<\/strong><\/td>\n<td>Duojia<\/td>\n<\/tr>\n<tr>\n<td><strong>Place of Origin<\/strong><\/td>\n<td>Hebei, China<\/td>\n<\/tr>\n<tr>\n<td><strong>Measurement System<\/strong><\/td>\n<td>Metric<\/td>\n<\/tr>\n<tr>\n<td><strong>Application<\/strong><\/td>\n<td>Heavy Industry, General Industry, Automotive, Construction<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h4><strong>Product Features<\/strong><\/h4>\n<p>Our DIN 577 Yellow Zinc Plated Square Nuts are a top choice for their functional design and robust finish.<\/p>\n<ul>\n<li><strong>Enhanced Corrosion Protection:<\/strong> The yellow zinc chromate coating offers superior resistance to rust and corrosion compared to clear zinc, ideal for outdoor and industrial use.<\/li>\n<li><strong>Excellent Anti-Loosening Performance:<\/strong> The square shape locks against flat surfaces and in channels, effectively resisting rotation and loosening caused by vibration.<\/li>\n<li><strong>Large Wrenching Surface:<\/strong> The four flat sides provide a secure grip for wrenches, enabling easy and high-torque tightening.<\/li>\n<li><strong>Cost-Effective Durability:<\/strong> Offers a great balance of enhanced corrosion resistance and strength at a more economical price point than stainless steel.<\/li>\n<li><strong>Multiple Strength Options:<\/strong> Available in various steel property classes to match the load requirements of your specific assembly.<\/li>\n<li><strong>DIN 577 Compliance:<\/strong> Guarantees dimensional accuracy, quality, and interchangeability for all your fastening needs.<\/li>\n<\/ul>\n<h4><strong>Product Applications<\/strong><\/h4>\n<p>The combination of a robust shape and a protective finish makes these nuts highly versatile.<\/p>\n<ul>\n<li><strong>Automotive Industry:<\/strong> Widely used for chassis fastening and under-body components where resistance to road spray and environmental elements is required.<\/li>\n<li><strong>Construction and Structural Connections:<\/strong> Ideal for outdoor structures, framing, and other connections where enhanced weather resistance is necessary.<\/li>\n<li><strong>Heavy Industry and Machinery:<\/strong> Perfect for assembling heavy equipment and machinery that operates in demanding industrial environments.<\/li>\n<li><strong>Agricultural Equipment:<\/strong> Provides durable, weather-resistant fastening for tractors, harvesters, and other farm implements exposed to the outdoors.<\/li>\n<li><strong>General Industrial Use:<\/strong> A reliable choice for any application requiring a strong, corrosion-resistant fastener with excellent anti-rotation properties.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>As a premier factory and manufacturer in China, we specialize in producing high-strength DIN 577 Square Nuts with a durable Color Galvanized (Yellow Zinc Plated) finish.
