Indandatho yesitoreji ye-Teng Tools ilungele ukugcina inhlanganisela nama-ring spanner aphindwe kabili. Iringi inogqinsi ngo-7mm futhi ingasetshenziselwa ukugcina noma ukubamba noma yini iringi engangena kuyo.
Iringi icishe ibe ngu-40mm ububanzi, 110mm ubude futhi yenziwe nge-Polioxymethylene (POM). I-POM i-thermoplastic yobunjiniyela esetshenziswa ezingxenyeni ezinembayo ezidinga ukuqina okuphezulu, ukungqubuzana okuphansi, nokuzinza okuhle kakhulu kwe-dimensional.
