A roller bolt and nut is a type of fastener used to join two or more objects together. The roller bolt consists of a cylindrical rod with a series of slightly raised ridges or rollers spaced at regular intervals along its length. The nut has a corresponding set of slots or channels in its top surface that match the spacing of the rollers on the bolt. When the nut is tightened onto the bolt, the rollers engage with the slots in the nut, allowing the bolt to rotate freely while remaining securely anchored in place. Roller bolts and nuts are often used in applications where frequent adjustment or removal is required, such as in furniture construction, industrial machinery, and automotive assemblies.
