Compatibility
- Fits: Siegmund System 28 welding tables and tooling with Ø28 mm bores on a 100 mm grid. Siegmund System 28 accessories also fit other 28 mm system welding tables with Ø28 mm bores on a 100 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.
- Not compatible: System 16 (Ø16 mm) tables; Siegmund builds each system around one bore size.
- Works with: other Siegmund System 28 clamps, bolts, stops, squares and U-squares on the same table.
- Care & grounding: anti-spatter spray, CleanBasic cleaner, Ground Connection Comfort (S16/S28).

Engineering support & demos
Engineering support comes with your purchase: fixture design, layout drawings, CAD and 3D models, site visits and cobot cell planning, handled by Travis Hardcastle at BTH Sales or by Siegmund directly. BTH Sales does not sell cobots; for cobot cells we help with table integration and fixturing (see cobot welding with Siegmund tables). Live demos at our St. Marys showroom are by appointment (book a demo), and we offer video demos if you are outside Ontario. BTH Sales is family-owned, founded in 2001, and has been the exclusive Canadian importer of Siegmund since 2018.
Typical uses
- Quick, powerful clamping of welding parts with a ratchet action (Siegmund).
- Repeated clamping at a set force: Siegmund says the force can be set individually with the grating.
- Siegmund describes System 28 as ideal for light to heavy components and designed for maximum clamping forces, multi-ton structures and high distortion forces.

Frequently Asked Questions
How is the fast tension clamp different from a screw clamp?
Siegmund describes the Professional Fast Tension Clamp as a ratchet clamp for clamping welding parts quickly and powerfully, with the force set individually by the grating. The Professional Screw Clamp 280610.N uses a spindle instead, with a hexagon socket insert for setting the force with a torque-limiting wrench. Siegmund rates both at 5 kN.
Can I replace worn parts instead of buying a new clamp?
Yes. Siegmund sells the spare parts individually. Its parts list for this clamp is 280632.N, 280637.N, 280617 and 280662.2. Email sales@bthsales.ca with the part number you need.
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.
