DIN 127 specifies split spring lock washers. When compressed, the split ends bite into the mating surfaces, providing a spring force that maintains tension and resists loosening caused by vibration or thermal cycling.
SRG Fasteners supplies DIN 127 Type A (bent ends) and Type B (flat ends) spring washers for automotive, railway, and heavy engineering sectors.
Frequently Asked Questions
Can I use a spring washer with a flat washer?
Yes, placing a flat washer under the spring washer is common to protect the mating surface from being scarred by the sharp edges of the split ring.
