Rampa insert type SKZZ
Rampa wood screw-insert, type SKZZ with inner-hexagon drive, unthreaded lead to facilitate mounting.
Rampa wood screw-insert type SKZZ is only available in M6X13mm and can be mounted without special tooling in middle hard wood thanks to the serrated outerthread.
Thanks to the unthreaded lead, the insert will fall into position before starting to screw, what ensures mounting in the rigth angle (that follows the drilled hole).
