This unique geometry is the key to their function. When a bolt or nut is tightened, the washer flattens, and its hardened, square-cut ends bite into the underside of the bolt head or nut and the mating surface. This dual-action mechanism\u2014combining continuous spring pressure with mechanical resistance\u2014effectively prevents counter-rotation and loosening. We offer these washers in a variety of materials to suit diverse operational needs. The standard carbon steel option, often finished with a zinc plating, provides excellent strength and corrosion resistance for general applications. For more challenging environments involving moisture or chemicals, our stainless steel A2 (304) and A4 (316) variants offer superior corrosion protection, ensuring maximum durability and a longer service life for critical assemblies.<\/p>\n<h4><strong>Product Parameters<\/strong><\/h4>\n<p>The following tables outline the detailed specifications for our DIN 127B Spring Lock Washers.<\/p>\n<p><strong>General Specifications:<\/strong><\/p>\n<div class=\"MarkdownTable_tableContainer__2k5Kh\" tabindex=\"0\" role=\"region\">\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Description<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Product Name<\/strong><\/td>\n<td>Spring Lock Washers \u2013 Type B (DIN 127B)<\/td>\n<\/tr>\n<tr>\n<td><strong>Standard<\/strong><\/td>\n<td>DIN 127B<\/td>\n<\/tr>\n<tr>\n<td><strong>Material<\/strong><\/td>\n<td>Carbon Steel, Stainless Steel (A2-70 \/ 304, A4-70 \/ 316, A4-80)<\/td>\n<\/tr>\n<tr>\n<td><strong>Grade<\/strong><\/td>\n<td>4.8, 8.8, 10.9, 12.9<\/td>\n<\/tr>\n<tr>\n<td><strong>Finish<\/strong><\/td>\n<td>Plain, Polished, Zinc Plated (White, Yellow, Black)<\/td>\n<\/tr>\n<tr>\n<td><strong>Measurement System<\/strong><\/td>\n<td>Metric<\/td>\n<\/tr>\n<tr>\n<td><strong>Size Range<\/strong><\/td>\n<td>M2 &#8211;

The spring action maintains constant tension, while the sharp edges of the split ring dig into the mating surfaces, effectively preventing loosening under heavy vibration, shock, or thermal cycling.<\/li>\n<li><strong>Broad Material and Grade Selection:<\/strong> We provide these washers in high-strength carbon steel for general industrial use and in A2 and A4 stainless steel for superior corrosion resistance in marine, chemical, or outdoor environments. Multiple strength grades (e.g., 8.8, 10.9) are available to match the requirements of high-tensile bolts.<\/li>\n<li><strong>Strict Adherence to Standards:<\/strong> Manufactured in full compliance with DIN 127B specifications, our washers guarantee consistent dimensions, mechanical properties, and performance. This ensures perfect interchangeability and reliable function in any standard application.<\/li>\n<li><strong>Comprehensive Size Range:<\/strong> With a vast inventory of sizes ranging from M2 to M100, we can supply the right washer for everything from delicate electronics to massive structural assemblies, making us a one-stop solution for your projects.<\/li>\n<\/ul>\n<h4><strong>Product Applications<\/strong><\/h4>\n<p>The robust design and reliable performance of DIN 127B Spring Lock Washers make them indispensable across a multitude of industries and applications where joint security is paramount. In the <strong>automotive sector<\/strong>, they are used extensively in engine mounts, suspension systems, and chassis assemblies to counteract constant vibrations and ensure components remain tightly fastened. For <strong>heavy industry and construction<\/strong>, these washers are critical for securing bolts on heavy machinery, structural steel frameworks, and large-scale equipment, preventing catastrophic failures due to loosening. In <strong>general manufacturing<\/strong>, they are a staple for assembling industrial machinery, conveyor belts, and production line equipment. Furthermore, the stainless steel variants are the top choice for <strong>marine applications<\/strong>, chemical processing plants, and outdoor infrastructure, where they provide long-lasting protection against corrosion while maintaining a secure, vibration-proof connection. Their simplicity and effectiveness make them a foundational component in any high-integrity bolted joint.<\/p>","protected":false},"excerpt":{"rendered":"<p>Discover the superior locking performance of our DIN 127B Spring Lock Washers, expertly engineered to secure bolted joints against loosening caused by vibration and dynamic loads. As a leading manufacturer with over 25 years of experience, we produce high-quality fasteners designed for reliability and endurance. These spring washers, also known as split lock washers, are helical-split rings that exert a powerful spring force when compressed. This action significantly increases friction and creates a mechanical lock, ensuring the integrity of your assemblies. Ideal for a wide range of demanding environments, our DIN 127B washers are manufactured from premium materials to provide a simple yet highly effective anti-vibration solution.
