Washers are widely used in engineering and are typically used as a spacer, a locking device, or simply to spread the load of the threaded fastener with which it is to be used. Washers are most commonly used with nuts, screws and bolts.
However, the use of washers does add complications when assembling products requiring same.
Firstly, the user has to align the washer to the aperture of the nut or alternatively, place it over the fastener with which it is to be used. Given the size of some washers, it is easy to drop or misplace it during use.
Then, the user has to keep the washer in alignment as the nut or fastener is mated with its complementary member. Again, given the size of some washers, the user can easily drop the washer and/or nut/fastener.
The process of mating the washer and nut/fastener must then be restarted, either by locating the dropped items or finding replacements. This is time consuming, adding to the assembly process, or wasteful if replacements have to be found.
It is an object of the present invention to address the foregoing problems or at least to provide the public with a useful choice.
