The DIN 127 Spring Washer, also known as a lock washer, is a high-precision fastening component engineered to prevent nuts and bolts from loosening under vibration or fluctuating temperatures. By providing a constant elastic force against the nut, these washers increase friction between the mating surfaces, ensuring a secure and stable connection in critical industrial assemblies.
Manufactured from high-grade carbon steel and available in a wide range of sizes from M5 to M52, our DIN 127 washers are designed to meet rigorous international standards including ISO, DIN, ANSI/ASME, JIS, and GB. Whether for heavy industry or automotive applications, these washers offer superior anti-loosening performance and durability to safeguard your structural integrity.

Frequently Asked Questions
The primary function is to provide an elastic force that increases friction between the nut and the bolt, effectively preventing the fastener from loosening due to vibration or pulse.
Generally, a flat washer is not required unless you need to protect the installation surface of the fastener or distribute the load over a larger area.
Our DIN 127 washers are manufactured from high-quality carbon steel, available in various grades including 4.8, 8.8, 10.9, and 12.9 to suit different strength requirements.
They are widely utilized in heavy industry, mining, water treatment, oil and gas, automotive, and general manufacturing where vibration resistance is critical.
We offer a variety of finishes including Zinc plating, Black oxide, Plain, and Hot Dip Galvanized (HDG) to ensure performance in various environmental conditions.
