Burnished Fast Clamping Bolt with twistlock (Item No. 2-160512, also known as S2-160512), perfect connecting element between Siegmund components. It features especially large balls, which protect the bevel of the bore holes as a result of low surface pressure. The fourth ball located in the center, reduces internal friction and strengthens the power of the handwheel. The new design of the bolt is not equipped with O-rings, but it still is easy to clean. This Bolt is NOT approved for combining tables and U-shaped squares! Clamping torque dependent on table type.
