Introduction
Double-stacked self-locking (locking) washer DIN25201 is composed of two pieces of inner tooth surface bite, the outer side has a radial oblique fine surface tooth pattern, and the inner side is a large-angle helical tooth surface.The angle of the helical tooth surface is greater than the angle of the thread. When the connecting piece is vibrated, the bolted connection will tend to loosen with continuous vibration. Only the helical tooth surface on the inside of the washer is allowed to produce relative dislocation, resulting in lifting tension, so as to achieve a complete anti-loosening effect.Double-stacked self-locking (locking) washers use geometric principles to safely lock bolted connections in strong vibration.
There are several advantages：
a．Highest safety performance
b．Prevent loosening due to vibration and dynamic load
c．Easy to install and disassemble, not affected by the original clamping force
d．The locking effect is not affected by lubrication
e．Regardless of the level of preload, it has a good locking effect
f．Can unify the level of preload
g．Has the same temperature characteristics as standard bolts/nuts
h．It can be disassembled and reused many times, and the performance is still guaranteed. Double-stacked self-locking (locking) washers are used when the bolts are fastened to the link, which can completely lock the bolts exposed to severe vibration and dynamic loads, and the anti-loosening performance is very stable.
