Nobü captive washers have a lip on one side and are used to secure screws. They are available for screws with metric threads M3 to M8 or inch threads 1/8‘ to 1/4’. Their inner diameter ranges from 6.5 to 8.5 mm, the outer diameter from 9.0 to 27.6 mm and the height from 1.2 to 2.6 mm. Made from robust natural nylon, these anti-loss washers reliably secure screw connections.
These anti-loss washers enable simple, time-saving pre-assembly, especially in hard-to-reach places. They do not require any special tools. The inner diameter of the washer is smaller than the diameter of the thread, which means that it engages in the thread and therefore cannot be lost. The captive disc can only be removed by unscrewing it. Therefore they can be used only once. Due to the low height of the lip, conventional washers can be subsequently replaced by these captive washers without the need for structural modifications.
Nobü captive washers are used with fully threaded screws under the screw head or nut to secure connections, e.g. in electrical appliances, vehicles, toys or in mechanical engineering. Thanks to the facet, they hold screws and washers together before tightening and ensure stable, long-lasting connections. They are equally suitable for industry and trade.
