Ulwakhiwo lwezikrufu zokuzicofa. I-self-tapping screw nganye yenziwe ngamacandelo amathathu: intloko, intonga kunye nokuphela kwentonga. I-self tapping screw nganye yenziwe ngezinto ezine: inkangeleko yentloko, indlela yokutsala, uhlobo lwentambo, indlela yomsila.
1. Imbonakalo yentloko
Iintloko ziza kuzo zonke iimilo kunye nobukhulu. Kukho umlomo ongqukuva (isiqingatha sentloko engqukuva), intloko engqukuva engqukuva, iflange yomlomo ongqukuva (enephedi), iflange yentloko engqukuva engqukuva (enephedi), intloko yepani, ipani yentloko yeflange (enephedi), intloko ephikisayo, intloko ebambeneyo enesiqingatha, icylindrical. intloko, umphezulu ongqukuva wecylindrical, intloko yophondo, intloko ene-hexagonal, intloko ene-hexagonal flange, i-hexagonal flange (enephedi).
2. Indlela yokutsala kunye nokujija
Indlela yesikruru ibhekisa kufakelo kunye nezikrufu zokuqhobosha xa isikrufu sentloko sigqwethekile, ngokwesiseko kukho isikrufu sangaphandle kunye nesikrufu sangaphakathi iindlela ezimbini. Ngokuqhelekileyo, i-wrench yangaphandle ivumela i-torque enkulu kunalo naluphi na uhlobo lwe-wrench yangaphakathi (i-concave groove). I-wrench yangaphandle: i-hexagonal, i-hexagonal flange surface, i-hexagonal flange, i-hexagonal flange, i-hexagonal shape yentyatyambo, njl. njl ipateni, unxantathu wangaphakathi, ihexagon yangaphakathi, i-engile ye-12 yangaphakathi, i-clutch groove, i-amagqabi amaqabunga amathandathu, i-torque ephezulu ye-cross groove, njl.
3. Uhlobo lwentambo yesikruru
Kukho iindidi ezininzi zemisonto, intambo yokucofa (intambo yezinyo ebanzi), intambo yomatshini (umsonto jikelele), intambo ye-drywall screw, i-fiberboard screw thread, kunye neminye intambo ekhethekileyo. Ukongeza, intambo inokwahlulwa ibe yi-pitch enye (intloko ephindwe kabini), i-pitch ephindwe kabini (i-multi-head), i-multi-pitch (intloko ephindwe kabini) kunye nokuba mangaphi amazinyo amaninzi entloko.
4, indlela yokugqibela
Imowudi yesiphelo somsila ikakhulu ibandakanya iindidi ezimbini: isiphelo sekhowuni kunye nesiphelo sobuhlobo. Nangona kunjalo, ngokweemfuno zesicelo, inxalenye yokuqinisa ekupheleni komsila inokuvelisa kwaye isebenze i-groove esebenzayo, i-groove, inxeba okanye inxalenye efana nokumila kwe-twist drill, njl. Kweminye imigangatho, i-cone iphelile okanye ekupheleni flat, kukho iindlela ezahlukeneyo ezifana ekupheleni komlomo ongqukuva.
