Chitsulo torsion kukameta ubweya bawuti ndi mkulu-mphamvu bawuti komanso mtundu wa muyezo chigawo chimodzi. Mabawuti achitsulo amagawidwa kukhala ma torsion shear amphamvu kwambiri mabawuti ndi ma bawuti akulu amphamvu kwambiri a hexagonal. Mabawuti akuluakulu amphamvu kwambiri a hexagonal ndi a zomangira zolimba kwambiri, pomwe mabawuti amphamvu kwambiri a torsion shear ndi mtundu wowongoleredwa wa mabawuti akulu amphamvu kwambiri a hexagonal kuti amange bwino. Bawuti yayikulu yachitsulo ya hexagonal imakhala ndi bawuti imodzi, nati imodzi, ndi mawaya awiri. Zokhotakhota zachitsulo zokhotakhota zimakhala ndi bawuti imodzi, nati imodzi, ndi washer imodzi. Pazigawo zazitsulo zonse, ma bawuti ofunikira achitsulo ndi giredi 8.8 kapena kupitilira apo, komanso magiredi 10.9 ndi 12.9, onse omwe ndi ma bawuti achitsulo amphamvu kwambiri. Nthawi zina, mabawuti pazinthu zachitsulo safuna electroplating.
