Compatibility
- Fits: Siegmund System 16 welding tables and tooling with Ø16 mm bores on a 50 mm grid. Siegmund System 16 accessories also fit other 16 mm system welding tables with Ø16 mm bores on a 50 mm grid.

Frequently Asked Questions
Can I use it in an elongated hole?
Siegmund says the Connecting Bolt should not be used in elongated holes and is not suitable for aluminum profiles. The Connecting Bolt with Collar (160583 to 160585) is suitable for elongated holes.
Double or triple?
Siegmund lists the double (160560.N, 25 mm) for connecting 2 components and the triple (160561, 37 mm) for 3 components.
Will it fit other 16 mm welding tables?
Yes, if the table has Ø16 mm bores on a 50 mm grid. Check the bore diameter and grid before ordering. Compatible tables from other manufacturers are often made from different materials and to different standards, so quality varies by manufacturer, compared with Siegmund's X8.7 tool steel.
