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.\u003c\/p\u003e\n\n\u003ch3\u003eKrollit Logistics and Support\u003c\/h3\u003e\n\u003cp\u003eShipping 3–5 business days from Krollit warehouse, Monteforte Irpino (AV).

All pins have a 20 mm diameter and a self-locking twist-from-the-top mechanism.\u003c\/p\u003e\n  \u003cp\u003eThe 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eIs the locking mechanism identical to the UJK Parf self-locking pin?\u003c\/summary\u003e\n  \u003cp\u003eYes. 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.\u003c\/p\u003e\n  \u003cp\u003eThe 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.

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.\u003c\/p\u003e\n  \u003cp\u003eFor 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eIs it possible to purchase pins in individual heights without purchasing the complete set?\u003c\/summary\u003e\n  \u003cp\u003eYes. 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.\u003c\/p\u003e\n  \u003cp\u003eThose who already have certain heights and only need a specific one can purchase the corresponding single pack.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eIs the Systainer Mini case compatible with the Festool Systainer system?\u003c\/summary\u003e\n  \u003cp\u003eThe container included in the set is named Systainer Mini by the manufacturer UJK.
