Tufnut Speedwrench
***CLOSEOUT***
SPEEDWRENCHES MARKED DOWN 50% WHILE SUPPLIES LAST
The Tufnut Speedwrench speeds Installation time. You just run the Tufnut onto the bolt, finger-tight. Spin the wrench onto the bolt until it meets the nut. Turn to tighten, then spin the speed wrench off.
The Speedwrench is used only for installing the nuts, and cannot unfasten them once installed.
For most installations, the regular two nut method is preferred because you can use a standard 7/8" open-end wrench.
In all cases, the Tufnut is removed using the standard two-nut method.
