Inkcazo yemveliso
Iibholiti zesakhiwo sentsimbi zizibholiti zokuqina okuphezulu kunye nodidi lwecandelo eliqhelekileyo. Ukusebenza kakuhle kokuqina, kusetyenziswe kwizakhiwo zetsimbi kunye nobunjineli bokuphucula umphumo wokukhawuleza. Kwizakhiwo zetsimbi eziqhelekileyo, iibholiti zensimbi ezifunekayo zibakala 8.8 okanye ngaphezulu, kunye nebanga le-10.9 kunye nebanga le-12.9, zonke ziyi-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-high-serial bolts iron structural bolts kunye ne-10.9 kunye ne-10.9 kunye ne-10.9 kunye ne-12.9.
Iibholiti zezakhiwo zensimbi zisetyenziswa ikakhulu kubunjineli bezakhiwo zentsimbi ukudibanisa iindawo zokudityaniswa kweeplati zentsimbi zesakhiwo.
Iibholithi zentsimbi zohlulwe zibe ziibholiti zokuqina okuphezulu kwe-torsion shear kunye neebholithi ezinkulu ezinehexagonal zokuqina okuphezulu. Iibholiti ezinkulu ezinamacala amathandathu aphezulu zezenqanaba eliphezulu le-screws eqhelekileyo, ngelixa iibholiti ze-torsion shear ezomeleleyo luhlobo oluphuculweyo lweebholiti ezinkulu ezine-hexagonal zokuqina kokwakhiwa okungcono.
Imibandela efuna ingqalelo ekwakhiweni kwayo
Ukwakhiwa kwebholithi yesakhiwo sentsimbi kufuneka kuqala kuqinise kwaye emva koko kuqiniswe, ibholithi yokuqala yokuqinisa intsimbi kufuneka isebenzise uhlobo lwempembelelo yombane okanye i-torque adjustable wrench yombane, kwaye ibholithi yokugqibela yokuqinisa intsimbi inesicelo esingqongqo, i-torque-shear uhlobo lombane kufuneka lusetyenziselwe ukuqiniswa kokugqibela kwe-torsion-type wrench kunye nohlobo lokutshiza lombane. ukuqiniswa kokugqibela kwebholithi yesakhiwo sentsimbi ye-torsion-shear. Iibholithi ezinkulu zentsimbi enehexagonal ezibandakanya ibhawuthi enye, indongomane enye, kunye newasha ezimbini. Ibholithi yolwakhiwo lwentsimbi yohlobo lwe-torsional shear, ngebholiti, i-nati, isakhiwo sentsimbi, ibholithi enkulu enehexagon edibanisa iwasha.
