防脱垫片，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。同时这些防脱垫圈也足够坚固，可以保持其形状并同时仍能夹紧螺钉不至于脱开。 

防脱垫片(止动垫圈)是固定螺钉、螺栓和光滑轴部件外部的紧固件，用于固定组件，防止螺杆在轴向的滑动和松脱。也称为推力螺母，它们适用于受振动、扭矩、热量或腐蚀影响的应用场合
。 预组装了防脱垫圈的螺钉或部件可以使最终组装过程更加有效。 

防脱垫片，也称为保持垫圈或防丢失垫圈、系留垫片，是设计用于在安装后锁定到位的紧固件，形成一个牢固的紧固组件。设计使其内径能抓住螺杆的外部。垫圈很容易滑动到螺钉上，但是
一旦组装好就被保持在螺钉上。

** 注： 防脱垫片，主要功能是起到保持和维系与之配套的螺杆不与之脱离，不可用来作为抗震防松为主要目的。

Retaining washers, also known as anti-loss washers or retaining rings, are fasteners that hold assemblies in place. 
These special washers from Sinohua are flexible enough to give when they are installed or intentionally removed, but they’re also sturdy enough to maintain their shape and secure other pieces of a configuration while still gripping the screw.

Retaining Washers for Pre-Assembly 
Retaining washers are often made with specially designed inside diameters to allow the washer to easily slide into place and grip the outside of a screw shank, bolt or product component. 
These washers from Sinohua are pre-assembled with a screw or component to ultimately make the final assembly process more efficient.

Retaining washers are fasteners that grip the outside of screws, bolts, and smooth shaft components to secure assemblies and prevent turning, slipping, and loosening.
Also,they are suitable for applications that are subject to slight vibration, torque, heat, or corrosion. 

Retaining Washers, of course, are also called Captive Washers due to captive function，they are fasteners that are designed to lock in place after installation -
creating a secure fastening assembly.The are designed so the inside diameter grips the outside of a screw shank. The washer easily slides on to screw, but is retained on the screw once assembled.
