The DIN 127 Spring Washer, also known as a lock washer, is a critical fastening component engineered to maintain tension and prevent nuts from loosening due to vibration or mechanical shock. By providing a constant elastic force against the nut and bolt, these washers significantly increase friction, ensuring long-term joint stability in demanding industrial environments.
Manufactured from high-grade carbon steel and available in a wide range of sizes from M5 to M52, our DIN 127 washers meet rigorous international standards including ISO, DIN, ANSI/ASME, JIS, and GB. Whether used in heavy industry, automotive assembly, or oil and gas infrastructure, these components provide the essential security required for safety-critical mechanical connections.

Frequently Asked Questions
The primary function is to provide an elastic force that tightens the nut, increasing friction between the nut and bolt to prevent the fastener from loosening under vibration or thermal expansion.
Generally, flat washers are not used solely for the spring washer's function. However, both may be used together if the installation surface or the fastener surface needs additional protection from damage.
We manufacture them from high-quality carbon steel in various grades including 4.8, 8.8, 10.9, and 12.9 to suit different load-bearing requirements.
Available coatings include Zinc plating, Black oxide, Plain (uncoated), and Hot Dip Galvanized (HDG) to ensure durability in various environmental conditions.
They are essential in Heavy Industry, Mining, Water Treatment, Automotive, Oil & Gas, and general manufacturing where equipment is subject to pulse or vibration.
