Compatibility
- Fits: Siegmund System 28 welding tables and tooling with Ø28 mm bores on a 100 mm grid. Clamp bushings let you use Siegmund System 28 components on welding tables with threaded holes, or, with the M10 bushing (280546), on T-slot tables together with the T-Nut 280547, rather than on Ø28 mm system bores. 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.
- Siegmund System 28: Clamp Bushings that let Siegmund components be attached to threaded holes (M8, M12 and M16, "e.g. on sliding blocks").
- T-slot tables: the M10 version 280546 pairs with T-Nut 280547 on T-slot tables. Ask sales@bthsales.ca about the T-Nut.
- 280546.4: "especially for fastening Siegmund parts with hexagonal sliding blocks".
- 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 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.

Frequently Asked Questions
Which clamp bushing matches my thread?
Siegmund offers 280546.1 for M8 (25 mm screw), 280546 for M10 (25 mm screw), 280546.2 and 280546.4 for M12 (25 mm and 50 mm screw) and 280546.3 for M16 (50 mm screw). The 280546.4 is especially for hexagonal sliding blocks.
Can I use Siegmund components on a T-slot table?
Yes, with the M10 bushing. Siegmund describes the Clamp Bushing for M10 thread (280546) as a connecting element between Siegmund components and a T-slot table, used together with the T-Nut (280547).
Do I need these on a Siegmund System 28 table?
No. On a System 28 table, components fasten directly into the Ø28 mm bores with System 28 bolts. Clamp bushings are for tables with threaded holes, or, with the M10 bushing (280546) and the T-Nut 280547, for T-slot tables. 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.
