When you look at professional motorcycle mechanics you will always find them with t- handle wrenches. The reason is you get a great feel for the quality of action for the bolt or nut. Electric tools are great but the only way you know if something is wrong is if the nut gets hot. Then it’s too late. These allow you to feel it and get it very close to the right torque if you have enough experience. Very easy to learn the right value and keep it with t- handles. 6 sided socket and great motion pro quality. Love it. Got this size to complete my set.
