1/2" Drive Torque Limiting Extension Bar Set, 5-Piece Impact Torque Limiter Set with 8 Inch Color-Coded CR-MO Torque Sticks (65 to 140 Ft-Lbs) for Locking Lug Nuts

I like that they are color coded and come in a hard case.

Each bar has a different diameter. The smaller the diameter, the easier the bar twists. When I say twists, I mean the bar "deforms" into a corkscrew. If you took the 65LB bar and put it on a breaker bar, it doesn't stop at 65lbs, it would just turn into a corkscrew.Impact drivers only turn a fraction of a revolution per impact. We will call it 1/100 of a revolution. Once the bar twists (turns into a corkscrew) 1/100 of revolution it just springs back and forth.In other words, the bar turns into a corkscrew, goes back to normal, turns into a corkscrew, goes back to normal, turns into a corkscrew, goes back to normal.

Good product

Custoer service is excellent ! Great company to do business with, and seem to be well built and work well.Suggestion; One piece of foam between the top and bottom would hold them in place and stop the paint from chipping.

Works great, they do what they are supposed to do

These are so convenient. Tested accurate vs my torque wrench.

Like a champ

Not a substitute for a torque wrench but close enough for my purposesComes in a good plastic case and the full-length color coding is a plus.

Helps prevent damage by overtightening fasteners.
