Who uses the UJK self-locking pin set and for what
The set is used by carpenters, woodworkers, and workshop outfitters who need variable protrusion reference pins to accommodate materials of different thicknesses on the same multi-function table. With the 4 available protrusions (10 mm, 30 mm, 40 mm, and 60 mm), most MFT table operations can be covered: from holding thin panels with the 10mm pins, to clamping thicker elements with the 60mm pins. The zero-tolerance self-locking mechanism, identical to the UJK Parf self-locking pin, eliminates any play at all four heights. The Systainer Mini case allows for tidy storage and transport of the set in the workshop or on site.

Who is the UJK 20mm self-locking pin set for
| Profile |
Compatibility |
Reason |
| Carpenter working with variable thickness materials on the same multi-function table |
Suitable |
The 4 protrusions (10–60 mm) cover thin panels, standard sheet materials, and carpentry elements without having to purchase separate individual pins |
| Anyone wanting a complete set of self-locking pins in a single purchase |
Suitable |
8 pins in 4 heights with Systainer Mini case included; more economical solution than purchasing individual pins separately |
| Anyone needing pins with a protrusion greater than 60 mm for very thick solid timber |
Not indicated |
The maximum protrusion of the set is 60 mm; for thick timber, the UJK Parf 120mm long self-locking pin is required, sold separately |
Not indicated for: tables with 20mm holes without chamfer, unless chamfered beforehand, and for solid timber thicker than what can be managed with 60mm protrusion.

Frequently asked questions
How many pins are included in the set and with what protrusions?
The set contains 8 pins in total: 2 x 10 mm, 2 x 30 mm, 2 x 40 mm, and 2 x 60 mm protrusion above the table surface. All pins have a 20 mm diameter and a self-locking twist-from-the-top mechanism.
The 4 protrusions cover most multi-function table operations: 10mm pins for thin materials and low-profile clamping, 30–40mm for standard panels, and 60mm for thicker elements or for use with a guide rail.
Is the locking mechanism identical to the UJK Parf self-locking pin?
Yes. The manufacturer UJK explicitly states that the pins in the set use the same self-locking mechanism as the UJK Parf self-locking pin. A simple twist of the top brings the tolerance to zero and locks the pin without tools.
The difference compared to the single self-locking pin is that the pins in the set are slightly more compact and simpler versions, with a fixed chamfer ring instead of the 2 interchangeable collars of the single version. The locking principle and precision are equivalent.
Is the set compatible with the Festool MFT/3 table?
Yes. All pins in the set are compatible with the Festool MFT/3 table and all grid tables with 20mm holes. The included chamfer ring ensures 90° perpendicularity and a flush fit in standard chamfered holes.
For tables with unchamfered holes, the UJK chamfering tool is available. The chamfer ring also prevents the pin from falling into the hole before locking, simplifying positioning during work.
Is it possible to purchase pins in individual heights without purchasing the complete set?
Yes. UJK also sells pins in individual heights (10 mm, 30 mm, 40 mm, and 60 mm) in packs of 2. The complete set in a Systainer Mini is the recommended solution for those who want all 4 heights in a single purchase at a lower cost than buying the 4 packs separately.
Those who already have certain heights and only need a specific one can purchase the corresponding single pack.
Is the Systainer Mini case compatible with the Festool Systainer system?
The container included in the set is named Systainer Mini by the manufacturer UJK. For specific compatibility with the Festool Systainer T-LOC or Systainer3 stacking system, it is recommended to check the container dimensions before purchasing, as compatibility depends on the generation of Systainer owned.
