Combination Fast Clamping Bolt (Item No. 2-000520, also known as S2-000520), developed specifically to bolt system 28 components to system 16 welding tables. The ball size and clamping force correspond with 16 mm fast clamping bolts. The fourth ball located in the center reduces internal friction and increases the force of the handwheel. The new design of the Fast Clamping Bolt dispenses with the O-rings, however it is still easy to clean. This Bolt is NOT approved for combining tables and U-shaped squares!
