Compatibility

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
What does the positioning bolt replace?
Siegmund says it cost-effectively substitutes for a second clamping bolt on squares that only require one clamping bolt for fastening.
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 28 connecting bolt.
Will it fit other 28 mm welding tables?
Yes, if the table has Ø28 mm bores on a 100 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.
