六角T型套筒是修摩托车必不可少的工具之一。在拆装四冲程发动机时,往往因扭力扳手粗大而无法使用,使用六角T型扳手就可轻而易举地拆装。而市场上卖的此类工具一般质量较差,硬度不够。我试用六角螺栓制做T型套筒,使用效果不错。 T-type hexagonal sleeve motorcycle repair is an essential tool. In the disassembly and assembly of four-stroke engines, often because of the torque wrench thick and unusable, the use of hexagonal T-wrench can easily disassembly. The quality of such tools sold on the market generally poor quality, hardness is not enough. I try to do T-type hexagonal bolts, the use of good results.
