Pamusoro pegomba rinosungirirwa pachidimbu chekubatanidza, 90-degree conical round socket inogadziriswa, uye musoro weflat muchina screw uri mune ino soketi yakatenderedza, iyo inoputika nepamusoro pechigamba chekubatanidza. Flat machine screws anoshandiswawo mune dzimwe nguva ane round head flat flat machine screws. Rudzi urwu rwe screw rwakanyanya kunaka uye rinoshandiswa munzvimbo idzo nzvimbo inogona kubvumira zvishoma.

Koni yemusoro weiyo countersunk head screw ine 90 ° cone angle. Kazhinji, iyo apex angle yeachangobva kutengwa drill bit ndeye 118 ° -120 °. Vamwe vashandi vasina kudzidziswa havazivi musiyano uyu wemakona, uye vanowanzoshandisa 120 ° drill Reaming, izvo zvinoguma nokuti countersunk musoro screws haisi kuomeswa kana kuomesa musoro countersunk screws, asi mutsetse pazasi sikuruu musoro, ndicho chimwe chezvikonzero nei izvo zvinonzi countersunk screws haigoni kubata zvakasimba.

Kuchengetedza panguva yekushandisa:
1.Taper yegomba reaming inofanira kuva 90 °. Kuti uzvisimbise, zviri nani kuve isingasviki 90 °, kwete kupfuura 90 °. Iri ndiro zano rakakosha.
2.Kana hupamhi hwepepa resimbi huri pasi pehupamhi hwemusoro we-countersunk head screw, unogona kushandura chidimbu chiduku, kana kuti kuwedzera gomba duku pane kuwedzera gomba kuitira kuti dhayamita yegomba rezasi rive rakakura uye chikamu chacho hachina kusimba.
3. Kana pane akawanda countersunk screw holes pane chikamu, nyatsojeka panguva yekugadzira. Kana chibooreso chatsveyama, zvakaoma kuona gungano, asi chinogona kusimbiswa chero bedzi chikanganiso chiri chidiki, nekuti kana sikururu isina kusimba Yakakura (inenge isingasviki 8mm), kana paine chikanganiso mugomba chinhambwe, iyo sikuruu musoro ichave yakaremara nekuda kwekumanikidza kana yakaomeswa, kana kuti ichasimbiswa.
