RS PRO, Plain Nylon Dome Nut, M4

From the trusted RS PRO brand, these dome nuts are ideal for applications where it is desired to hide or cover the end of a projecting screw thread. The dome shape can eliminate the possibility of snagging edges, which is ideal for capping off flexible threaded rods. The dome has a hexagon flange which is ideal for both hand and tool tightening for the application of appropriate torque. This flange also may eliminate the need for a washer to distribute the pressure of the nut.

The dome nut is made of nylon, which is weather-resistant and lightweight, and so perfect for light-duty applications and high voltage applications.

Dome nuts, sometimes called acorn nuts, are a versatile fastener used for aesthetic and practical reasons wherever a bare screw thread is a concern. Unlike using standard nut fixings, a dome nut completely covers the end of a screw. As such, it can be used in lieu of, or on top of, fastening nuts. These domed nuts can be used to cap threaded bars or make sure a surface is snag-free.
