DIN 127 Spring Lock Washers
DIN Standards are issued for various components including industrial fasteners such as the Metric DIN 127 Spring Lock Washer. DIN 127 washers are manufactured from stainless steel A2 and A4, steel, bronze, mild steel, copper, and free-cutting brass. DIN 127 is also known as split washers. DIN 127 washers are available in a wide range of sizes, shapes, finishes, and materials. Based on the requirement, we also provide DIN 127 A – Spring lock washers, Form A, and DIN 127 B – Spring lock washers, Form B.
Following are the specifications of German DIN 127 washers:
Characteristics:
- High wear resistance and hardness.
- Durable and reliable.
- DIN 127 washers have a trapezoidal shape.
- Complies with CSN 021741; UNI 1751; GOST 6402-70.
- Strength class: 5.8 or less.
- DIN 127 spring washers have a unique design with a split or curved shape.
Advantages:
- These washers are easy to install and have a sturdy structure.
- Prevent losing with spring lock washers.
- DIN 127 washers are spring washers that have a helix that turns to the left, enabling threads to be tightened in a clockwise manner.
