Lezi zinsimbi ze-torque ezishintshashintshayo zezinga lezimboni zenziwe ngokunemba ukuze zilethe ukuqiniswa okunembile nokuthembekile ezindaweni ezifunwayo. Atholakala kukho kokubili ukulungiselelwa okuvulekile (okulungele amapayipi, amashubhu, kanye nokucaciswa okuqinile) nokulungiselelwa kokuphela kwebhokisi (ngohlelo oluvikelekile, lwetorque ephezulu), lawa makhanda adidiyelwa ngaphandle komthungo nama-wrenches ajwayelekile angama-rectangular drive torque. Yakhelwe ukuqina kanye nezinguquko ezisheshayo zamathuluzi, ihlinzeka ngesixazululo esiguquguqukayo kakhulu sokuhlanganiswa kwemishini kochwepheshe, ukunakekelwa kwezimoto, nokulungiswa kwezimboni ezisindayo.

Lawa ma-Square Head Box-End Insets asezingeni lezimboni angamakhanda ashintshashintshayo aklanywe ngokunemba aklanyelwe izinhlelo zokusebenza zetorque ephezulu, anamasayizi okushayela amane (9x12mm kuya ku-27x36mm) kanye nokucaciswa kokuvula kusuka ku-4mm kuya ku-80mm. Iyakwazi ukuphatha imithwalo ye-torque ephezulu ukusuka ku-7 N.m ifike ku-3000 N.m, ihlinzeka ngesixazululo esiguquguqukayo nesiqinile sokuhlanganisa imishini yobuchwepheshe kanye nokuqina okunembayo ezindaweni eziqinile.

Okunemba okuphezulu kwe-Square Head Open-End Insets okuklanyelwe ukusetshenziswa kwetorque yezimboni. Ifaka isiphetho sedrayivu esiqinile (esitholakala ku-9×12, 14×18, 24×32, kanye no-27x36mm), lezi zifakiwe zinikeza ukusebenza okuthembekile kulo lonke uhla olubanzi losayizi wokuvula kanye nezidingo zetorque.

Iklanyelwe izinhlelo zokusebenza zezimboni ezisebenza kahle kakhulu, uchungechunge lwe-YouBar Ratchet Spanner Insert luwumngane ophelele wemisebenzi yetorque enembayo. Lokhu kufakwa kufaka idizayini eqinile ye-bi-directional, evumela ukushintshwa okungenamthungo phakathi kokuqiniswa nokukhulula imisebenzi ngisho nasezimweni ezinzima kakhulu.

Ukufakwa kwesipana sesikwele se-YouBar siklanyelwe ukudluliswa kwetorque enembayo. Idizayinelwe ukusetshenziswa nama-wrenches etorque enziwa ngesandla noma edijithali, lolu chungechunge luhamba phambili ezindaweni eziqinile nezimo ezikhethekile zezimboni. Kusukela ekumbiweni kukawoyela nokwakhiwa kwamandla kuya ekuhlanganisweni kwemishini okunembayo, i-YouBar iletha ukuqina nokuphepha okuphelele.
