A COUNTER SUNK (Barrel Nut) , also known as a Cross Dowel Nut or Sleeve Nut, is a cylindrical internally-threaded fastener designed to provide a strong, secure, and vibration-resistant connection between two components. The internal thread runs perpendicular to the barrel body, allowing a bolt to engage from the side and form a solid locked joint.
