防脱垫片 anti-loss washer
也称为止动垫圈或止动环，是一种易装配并将螺杆固定到特定位置的紧固件。这种防脱垫片通常具有特别设计的内径及一圈均匀分布的内齿，以允许垫圈容易地滑动到位并夹紧螺杆、螺栓或产品部件的外部。这些防脱垫片在安装时足够灵活，当然--如有需要拆除时也很简单。
Sinohua anti-loss and retaining washer is similar to our standard flat washers, but with a specially configured I.D. designed to grip the outside of the screw shank. The anti-loss washer slides on the screw easily, but is retained on the screw. For use in applications requiring pre-assembly of the screw and washer, to reduce final assembly cost.
So these anti-loss retaining Washers, of course, are also called Captive Washers due to captive function.
