Accessories

This set includes eight Vario clamping bolts for welding tables with 28-mm holes—four with clamping lever for quick repositioning, and four with screws for high clamping force. This allows you to secure a workpiece at multiple points simultaneously, even for large or complex assemblies.

What sets it apart is the height adjustment: Using the laser-etched scale , you can adjust each bolt continuously to the workpiece height—the wide clamping range from 0 to 75 mm accommodates even thick assemblies and stacked stops. The centering bolts and adjustment ring are made of phosphated steel, the clamping bolts are black-oxide finished, and the handle levers are made of die-cast zinc—clamping technology designed for the rigors of everyday welding.

Here's how to use it

  • Securing complex assemblies: Eight bolts distribute the clamping points across the grid—even in places where a clamp cannot reach the edge of the table.
  • Multiple clamping positions in parallel: with eight bolts, two assemblies remain clamped at the same time—the second assembly, already clamped, is ready for its weld seam.
  • Read the height instead of guessing: the scale adjusts each bolt with consistent precision—all clamping points are at the same height, and the workpiece lies flat.
  • Lever or screw: clamping lever (168 mm overall height) for fast cycling, screw (129 mm) where holding force matters.

Does this go with your table?

The bolts fit on welding tables with 28-mm holes for material thicknesses of 4 mm or greater—at RUWI, the welding table lifting table and the leg table. The individual bolts are available as Vario clamping bolts Ø 28; the same set for the 16-mm grid is available as Set 1 Ø 16 (0–36 mm); additional clamping tools are shown in the overview of clamps, vertical and horizontal toggle clamps.
