Mountain 16250 1/2-inch Drive Torque Wrench: Can anyone tell me if it measures torque for left-hand threaded fasteners or is it right-hand (clockwise) torque only?

Yes. The wrench is reversible so it will measure the torque for left handed threads.

I am not certain I understand the question, but I will attempt to answer it. Suppose you want to torque a bolt to 45 foot pounds. The shaft of the torque wrench has an engraved scale for, I believe, every five foot pounds. Turn the handle until the edge of it reaches 40 foot pounds and the handle has consecutive numbers engraved on it starting at 1, 2, 3, etc., finally stopping at 13. Reading the engraved numbers on the handle, turn the handle until 5 is facing you. You are at 45 foot pounds. The lowest reading possible on this torque wrench is 25 foot pounds. The torque wrench also come with an owner's manual explaining its use and care. I hope I have given you the information you needed.

I don't know why their customer service told Buck that info. In his review, he described the correct way to reverse it so that it does work for reverse-threaded applications. Reversing the head is the proper way to adjust the wrench to torque left-handed threads. The torque mechanism only works in one direction - clockwise is the default direction. Some wrenches have a push-through drive to get bi-directional torquing, but this one has a reversible head (some wrenches can't be reversed at all). It's not a big deal to reverse it. Doing so essentially "turns the wrench around" so that it will torque in a counter-clockwise direction. A "reversible ratchet head" feature is not the same as a "reversible ratchet" feature, and their product features clearly state it has a reversible head. Simply reversing the ratchet mechanism with the toggle only allows you to ratchet in both directions - it does not provide for torquing in the reverse direction.

I'm curious as to the discrepancies between answers here. Has anyone besides Buck actually tested the torque function on left/reverse threaded bolts? I can confirm that my Tekton 3/8" does NOT work to torque left threaded bolts.

Mine did not, but I tested it against NY brother's snapon 3/8 torque wrench, and found it to be accurate to within a 0.50ft-lb.

The reading might be slightly off if your using the extension bar after the Torque Meter; as the extension bar would be twisting. However I would expect the difference to be very small. In most bolted joints we are only after achieving 60-70% of the bolt allowable tension and that all the bolts are tensioned the same. Basically to clamp the joint together by friction. Therefore I would personally not worry unless your using a stupidly long extension bar after the torque meter. My thoughts anyway.

The CDI 2503MFRPH model I purchaced is reversible as advertised. I use the reverse to test "break away" torque. Left handed threads can be tightened using this torque wrench, also. Left handed threads are fairly rare, but older Mopar cars used them for wheels on passenger side of car if memory serves me correctly. Normally. a torque wrench that is not reversible will be damaged if used as a breaker bar for loosening.

No. It't not a torque wrench. It's an "Impact" wrench. It simply applies whatever torque is required (all the way up to it's maximum) to break fasteners loose or fasten them down. If you want to apply fasteners to a specific torque, you need a "torque" wrench.

No, This one is a 1/2" right handed thread. This did work good on the right side of a old furnace motor. I think I used larger washers that came with the wheel. I have seen some with left handed thread.

The bits are "left-handed" - yes. Correct - many times the screw will come out before requiring the extractor.

there is no torque adjustment in either direction. In the operator manual that came with it is tells you the following statements "Do not tighten the lug nuts with the impact wrench. Excessive torque may cause damage. Use a torque wrench to check the lug nuts are tightened to manufacturer specs." They want you to use the lug wrench that came with the vehicle so you do not over or under tighten the lugs. Also keep in mind that if the lug nuts are overtightened to start with this torque wrench may not loosen them. I only bought this torque wrench because I just had hip and knee surgery and thought it may help me out in an emergency. I never had to use it so I can't comment on that but I tried it in my garage and it worked. I loosened one on each of my 2 vehicles and that is all. It may have loosened more but I can't tell you for sure. I put road service through my insurance company on both my vehicles just to be sure. Hope this helps DMD

Since there have been conflicting answers, I'll link to the owner's manual: http://www.tektontools.com/PRODUCT_MANUALS/MANUALS_2000/24320_manual.pdf. It states clearly that the torque measurement only works in one direction.

this is not a torque wrench , but thank of it like a 1/4 inch drive .you can strip small dia. screws in plastic parts . i hope this was help full ?

Well, one thing for sure, it provides you the actual torque value you have reached. You might not like what you seen in the readout but it is what it is. It is still hard for me to accept the fact standard torque wrench can actually over-torqued the nut. Maybe it is because the sudden jerking movement did it.

Mt Tekton wrench was broken when it arrived, but my other ratcheting "clicker" - a Craftsman - does both RH and LH thread. The Tekton should work the same.

It can be calibrated the same way any torque wrench is cal'd. Any precision calibration shop will be able to do it. Scott Reilly, A&P Mechanic

I occasionally check it against my "glass torque wrench", one that I keep calibrated and only use to test. I found this to be absolutely accurate and consistent. I did what you wrote, bought a 1/2 and use a 3/8 adapter when necessary. Of course use a quality, short adapter to maintain accuracy.
