Usage

To use one, simply tighten the bolt down as much as you can with your fingers, be sure the thread is lined up and it screws on nice and easily, then when it’s as tight as you can get it with your fingers, use the torque wrench to apply the list bit of pressure to get it in place.

The last thing you want to do is strip your bolts, so be sure that you keep the torque wrench securely on the bolt you are trying to tighten, and you’re using the right size. If your wrench head is too big the constant slipping of the wrench will strip down the bolt’s head.

Then, you’ll want an accurate torque wrench so that you don’t tighten the bolts so much that they will never come undone. Or, so you don’t tighten the bolts not quite tight enough to remain in place.
