ISitshixo Semithwalo I-No Screw sisitshixo semithwalo esiyilelwe ukudityaniswa okusebenzayo nokugcinwa okulula. Esi sitshixo sinamacandelo amabini ahlukeneyo: umzimba wesitshixo kunye neqokobhe lesiseko esithintela ukubuyela umva, adityaniswa ngaphandle kwezikrufu. Icandelo lokutshixa liyatyibiliza lingene kwiqokobhe lesiseko ukuze lufakwe ngokukhawuleza nangokukhuselekileyo, nto leyo exhasa ukusetyenziswa koomatshini kwimveliso. Isibambo sokuqhaqha esihamba naso sohlula la macandelo mabini, ngoko ke ukugcinwa akufuni zixhobo kwaye akufuni ncedo lobungcali. Ngaphezulu kwama-80 ekhulwini esi sitshixo senziwe nge-ABS ekhaphukhaphu, emelana nokubethwa nokuguga kwaye yongeza ubunzima obuncinane kubahambi.
