The UJK Technology Cam & Wedge Clamping Set is a cam and wedge clamping set for multifunction tables, consisting of three 12mm stainless steel guide pups, a phenolic resin cam clamp surface, a CNC machined Valchromat HDF backstop, two wedges, and a spacer block. Designed and manufactured in the UK by UJK Technology, a brand launched by Axminster Tools in 2012, now under NuCo Tools Ltd. Distributed in Italy by Krollit, official UJK distributor since 2007.

- Hole compatibility: MFT tables with 96 mm hole grid and 12 mm dogs
- Backstop and wedge material: CNC machined Valchromat HDF, PEFC certified
- Cam clamp surface: phenolic resin with screw holes on a flat surface
- Number of backstop holes: 3 (two at 96 mm for lateral/longitudinal positioning, one for diagonal positioning)
- Included components: 3 guide pups, 1 cam clamp, 1 backstop, 2 wedges, 1 spacer

Who is the Cam & Wedge Clamping Set for?
| Profile |
Compatibility |
Reason |
| Carpenter with MFT table or surface with 96 mm holes |
Suitable |
The set uses the standard 96 mm hole grid with 12 mm pups to clamp the workpiece without cluttering the work surface. |
| Hobbyist performing routing, sanding, or carving on a perforated surface |
Suitable |
The cam clamping completely frees the top surface of the workpiece, allowing router passes, sanding, or chiseling without obstruction. |
| Those working on a traditional workbench without 12 mm holes at 96 mm centers |
Not indicated |
The system requires a 12 mm hole grid with 96 mm spacing; on standard workbenches without this geometry, the set is not usable. |
Not indicated for: workbenches without 12 mm holes at 96 mm pitch, processing very thin workpieces where the pups do not find sufficient support, and clamping applications on metals or hard composite materials that require higher clamping forces than the cam-wedge principle.

Frequently Asked Questions
What MFT tables is the UJK Cam & Wedge Clamping Set compatible with?
The set is compatible with all tables and perforated surfaces that use a 12 mm hole grid with 96 mm spacing, the standard for multifunction tables like Festool MFT and surfaces made with the UJK Parf system.
The backstop is positioned by inserting the 12 mm pups into the holes of the surface. The 96 mm spacing is the de facto standard for MFT tables on the market. Surfaces made with the UJK Parf Guide System comply with this geometry. Those who have a surface with 20 mm holes at 96 mm pitch must verify that the 12 mm pups fit into the holes without excessive play.
How many pieces does the set include and can the components be purchased separately?
The set includes 7 components: 3 x 12 mm stainless steel guide pups, 1 x phenolic resin cam clamp, 1 x Valchromat backstop, 2 wedges, and 1 spacer. According to the information available on the UJK website and authorized distributors, all components are also available separately.
The ability to purchase individual parts is useful in case of wear and tear on the wedges or spacer, the parts subject to the most mechanical friction during continuous use. For the codes of individual components, contact Krollit at +39 0825-1494022.
Can the cam clamp be used on a non-perforated surface?
Yes. The cam clamp has integrated holes that allow it to be fixed with screws to any flat surface, even without a 96 mm hole grid. In this case, the pups are not used, and clamping is done only with wedges and a spacer.
This feature extends the use of the set to traditional workbenches, temporary MDF panels, or temporary assembly surfaces. The cam-wedge principle remains unchanged: the workpiece is clamped laterally without any obstruction on the top surface.
Is the Valchromat of the wedges certified and how is it different from standard HDF?
The Valchromat used for the backstop, wedges, and spacer is PEFC (Pan European Forest Council) certified for sustainable forest management. It is a through-colored HDF, more resistant to moisture and abrasion than standard HDF.
CNC machining ensures precise tolerances on the contact surfaces, which are crucial for clamping stability. Unlike raw HDF, Valchromat maintains stable dimensions over time, reducing the risk of wedge deformation in environments with typical humidity variations found in workshops and joinery.
In how many positions can the clamping be oriented with the included backstop?
The backstop has three holes for pups: two spaced at 96 mm for lateral or longitudinal positioning relative to the workpiece, and a third for diagonal positioning. This allows the workpiece to be clamped in at least three orientations without moving the cam clamp.
Diagonal positioning is useful when working with angles or when the workpiece geometry does not fit the orthogonal axes of the grid. In combination with the three pups that can be freely positioned in any hole of the surface at 96 mm, the clamping configurations cover most machining situations on an MFT table.
