The patented PC bolts are the cornerstone of the Demmeler system. With a simple twist of a wrench in the head of the bolt, any component can be attached to another element or the table in a matter of seconds!  By turning the head, five internal balls are driven out into the chamfer found on the backside of every bore. All threads are internal, protecting them from dirt, spatter and other shop hazards. An integral O-ring in the body of the bolt allows for one-handed tightening (no need to reach under the table and hold the bolt from turning - the O-ring does that). So simple, yet so powerful
