M'malo mwake, imadalira mwachindunji kuuma kwake "kudula" kapena "kufinya" ulusi wamkati womwe umagwirizana nawo pazinthu zolumikizira, potero kukwaniritsa kulumikizana kolimba. Izi zimapangitsa kuti zikhale zoyenera kwambiri pazogwiritsa ntchito monga kulumikiza mbale zowonda komanso kusonkhana mwachangu. Mapangidwe okhazikika amawonetsetsa kuti mutu wamakina woyikiratu umizidwa kwathunthu pamtunda popanda kutulutsa zopinga kapena kusokoneza mawonekedwe. Izi ndizofunikira makamaka m'magawo monga kupanga mipando ndi kusonkhanitsa zinthu zamagetsi.

Kunena mwadongosolo, chipangizo chodzipukutira cha countersunk nthawi zambiri chimakhala ndi magawo atatu: mutu, screw ndi nsonga. Mutu wa makinawo umapangidwa ndi ma groove odutsa, ma groove owongoka kapena zida zina zotumizira ma torque. Chigawo cha screw chili ndi ulusi wodzipangira mwapadera. Maonekedwe am'mbali ndi mamvekedwe a ulusiwo amasiyana malinga ndi zofunikira zogwiritsira ntchito.

Makina a Countersunk self-tapping opangidwa ndi zipangizo zosiyanasiyana ali ndi ubwino ndi zovuta zawo malinga ndi makina, kukana kwa dzimbiri, mtengo, ndi zina zotero.
