Bay Supply is home to the CAK knurled blind rivet nut series by Sherex. Similar to the CAL rivet nut series, CAK rivets offer the same impressive strength to easily attach items while keeping them securely locked in place. However, unlike the CAL series, a CAK knurled blind rivet nut has a small flange. This means that the CAK rivet nut is better suited for applications that require a near flush installation. Additionally, when CAK rivet nut inserts are installed into soft materials, they offer tremendous spin out resistance. Shop now!
