This bolt comes without the slot for O-rings. This ensures a smooth surface of the bolt body.

The bolt without slot is particularly suitable for clamping aluminum profiles and is also still compatible with the entire Siegmund range.

The fast clamping bolt with twistlock is the ideal connecting element between Siegmund components.

Note: This bolt MUST NOT be used for connecting tables and U-shaped squares!

Our recommendation when working with aluminum profiles.

Clamping torque dependent on material.

When clamping aluminum parts, the bolts must only be tightened hand-tight.
