Domed (Acorn) Nuts(Sales Unit:Box, Pkg.)

Category page for Cap Nuts. For MISUMI, you can select from nominal, type of material and type of surface processing. A range of products are handled, from regular metric thread types through imperial thread types.
In addition to general cap nuts, there are also serrated types, disc spring types, and friction types for preventing screws from loosening.
[Cap Nuts]
Cap nuts are hexagonal nuts closed on one side, so the threaded hole does not extend the whole length. This prevents bolts from sticking out, giving a beautiful appearance and preventing issues caused by snagging on protruding bolts.
These are sometimes called "cosmetic nuts" because they improve appearance and enhance safety. However, since one end of the nut part is blocked, one must consider the length of the thread relative to the bolt length to be used.
