16mm or 28mm: which clamps fit your table?
Match the clamp to your table's bore. The two systems are not interchangeable.
| System 16 (16mm) | System 28 (28mm) | |
|---|---|---|
| Bore diameter | Ø16 mm | Ø28 mm |
| Bore grid | 50 mm | 100 mm |
| Siegmund recommends it for | Light to medium-duty work and precision fixtures; the close 50 mm grid lets small components be fixed with high precision | Light to heavy components; designed for maximum clamping forces, multi-ton structures and high distortion forces |
| Professional Screw Clamp, max. clamping force | 2.5 kN (160610) | 5 kN (280610.N); XL 7 kN (280612.N) |

Frequently Asked Questions
Which System 28 clamp has the highest clamping force?
On siegmund.com the Professional Screw Clamp XL (280612.N) lists 7 kN maximum clamping force. The Professional Screw Clamp (280610.N), the 45°/90° version (280630.N) and the Professional Fast Tension Clamp (280615.N) list 5 kN, the Pipe Elbow Clamp (280626.N) 4 kN, the Basic Pipe Clamp 90°, Basic Pipe Clamp 180° and Pipe Clamp Universal 3 kN, and the screw clamp with vertical action toggle 2.5 kN.
How are the pipe clamps held in the table bore?
Siegmund says the vertical pipe of the Basic Pipe Clamp 180° (280625) and the Pipe Clamp Universal (280604) is secured in the system bores with an Adjusting Ring, item 280653.N; the Pipe Elbow Clamp (280626.N) is also fastened with an adjusting ring. The vertical pipe is 250 mm long on the Basic Pipe Clamp 180° and the Pipe Clamp Universal.
Can I set the clamping force precisely?
Yes, on the professional screw clamps. Siegmund says the hexagon socket at the top of the handle of the Professional Screw Clamp, the XL and the 45°/90° version lets you set the clamping force precisely with a torque wrench.
Where are the fast clamping kits and clamp spare parts?
Fast clamping kits are in the Siegmund System 28 Fast Clamping Equipment collection, and prisms, spindles, bars and other clamp parts are in the Siegmund System 28 Clamp Replacement Parts collection. Siegmund says its professional clamps are built so that spare parts can be ordered individually.
Will System 28 clamps fit a 16mm welding table?
No. System 28 clamps are made for Ø28 mm bores on a 100 mm grid. A table with Ø16 mm bores on a 50 mm grid needs System 16 clamps. System 28 clamps also fit other 28 mm system welding tables with Ø28 mm bores on a 100 mm grid.
