CAK – Small Flange, Knurled, Round Body Rivet Nut (Open End and Closed End)
The CAK small flange, knurled, round body rivet nut is a popular Sherex by PEM fastener used in a variety of applications.

Small flange is for a near flush installation and the knurls provide grip into the base material to prevent the rivet nut from spinning after installation.
