I-Countersunk ne-non countersunk yizinhlobo ezimbili eziyisisekelo zemiklamo yekhanda lesikulufa. Amakhanda angashiyiwe ahlanganisa amakhanda ahlanganisayo, amakhanda ezinkinobho, amakhanda ayisilinda, amakhanda ayindilinga, amakhanda e-flange, amakhanda ayi-hexagonal, amakhanda epani, isiyingi, isikwele, amakhanda ama-truss, njll., kuyilapho imiklamo yekhanda elishoniwe ihlanganisa ikakhulukazi amakhanda asicaba, ama-ellipses, namakhanda ezimpondo.
Ikhanda lesikulufu le-countersunk lidizayinelwe ukuthi lishiswe noma libe ngaphansi kancane kobuso bento ngemva kokufakwa okuphelele. Inomumo oyi-conical one-groove eyi-conical phezulu. Inhloso yembobo ephikisayo ukudala indawo ebushelelezi nefanayo ngemva kokuqinisa isikulufu. Uma isikulufu se-countersunk sifakwe ngokugcwele, ikhanda lizoguquguquka noma libe ngezansi kancane kobuso bento, lithole ukubukeka okungenamthungo. Izikulufu ze-Countersunk zivame ukusetshenziswa uma kudingeka indawo eyisicaba futhi ebushelelezi, futhi ngokuvamile zisetshenziswa ekwenzeni ukhuni, amakhabethe, nezinhlelo zokusebenza ezibeka phambili ubuhle nemigqa ehlanzekile.
Ngakolunye uhlangothi, amakhanda esikulufu angashiyiwe awanawo umumo oyiconical noma i-concave top, nekhanda elivezwe ngokuphelele. Inhloso yabo yokuklama akukhona ukuthi ixutshwe nengaphezulu lempahla. Ngokuphambene, anamakhanda amakhulu, ayisicaba, noma ayindilinga asabonakala uma isikulufu sesiqiniswe ngokugcwele. Uma ukubukeka kwesikulufu kungekona ukukhathazeka futhi kwamukeleka noma kudingekile ukusebenzisa amakhanda angaphandle noma aphakanyisiwe, amakhanda ngezikulufu ezingashiyiwe ngokuvamile asetshenziswa. Lezi zikulufu zivame ukusetshenziswa ekwakheni, ekwenzeni insimbi, nasezinhlelweni ezibeka kuqala amandla, ukuqina, nokusebenza kunobuhle.
