Items 160528 and 160529: Siegmund Flush Mount Bolt, burnished, double and triple, for System 16. Siegmund uses it as a hidden connection between its elements; the four-ball design matches its other connecting bolts and the head disappears into the bore, flush with the clamped component. BTH Sales is the exclusive Canadian importer of Siegmund.

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. 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.

Frequently Asked Questions
Can I use it on aluminum profiles?
No. Siegmund lists the 160528 as not suitable for aluminum profiles or elongated holes. For aluminum profiles, Siegmund recommends the Flush Mount Bolt without slot (AP160528 to AP160530).
Can I use this bolt to connect two tables?
No. Siegmund says this bolt must not be used for connecting tables and U-shaped squares. For that, use a Siegmund System 16 connecting bolt.
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.
