The burnished fast clamping bolt with screw top is the ideal connecting element between Siegmund Work components with a material thickness of 15 mm.
It features especially large balls, which protect the bevel of the boreholes 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.

  • Clamping torque dependent on table type
  • with Hex wrench 6mm

The burnished clamping bolt is a connecting element between tables, stops and squares. It ensures sturdy and precise bolting as a result of the large ball diameter.

The burnished connecting bolt is especially designed to serve as a fixed long-term connection between large Siegmund components, e.g. tables or U-shaped squares.
The flush mount hexagon socket and the ability of the clamping bolt to center itself, facilitate simple assembly.
The countersunk head and the countersunk-head screw are equipped with a 10 hexagonal bit for clamping. The connecting bolt enables sturdy bolting and is not suitable for use in elongated holes.

The flush mount bolt is used as a hidden connection between Siegmund elements. Its design corresponds with other connecting bolts with four balls.
Its head disappears into the borehole, to make it flush with the clamped component. The flush mount bolt is not suitable for use in elongated holes.


Our system includes fast clamping bolts, clamping bolts, flush mount bolts and connecting bolts.
With the wide range of bolts, you can optimally fix various accessories such as squares on the worktable to achieve precision.

Our bolts are made of hardened high-alloy steel and have higher strength, corrosion resistance and hardness due to additional finishes such as burnishing or nitriding.

Generally, bolts are used in combination with other accessories for clamping workpieces on the work tables.
Depending on the type of bolt, they have different functions.
Clamping bolts are the connecting elements between tables, stops and squares. Fast clamping bolts are ideal for connecting between all Siegmund Work components.
