torque wrench

I prefer a breakout wrench to the deflection(?) type wrenches. I have a 1/2" Snap-On, but only because I bought it at a garage sale for $20. A 1/2" is fine, but a 3/8" is a lot handier for most jobs.
 
A click or snap type is easier to be accurate with.
I like expensive tools Snap On Mac and Proto.
But Craftsman Sears and Black Hawk from NAPA are also good tools. Jim
 
pretty much has to be 1/2 " drive , unless your torquing in the inch pounds with small bolts , then 3/8" drive is what you would use. i use snap-on.

Wouldn't a ft lb 3/8 wrench work for oil pan bolts etc? I have just seen clearance problems with my 1/2. Like I had to run an extension bc the head and socket were too big to fit in the space, but a 3/8 would probably fit. That extension just screwed up all my torque settings.
I just went to the Snap-On website
3/8 20-100 ft lb $262
1/2 50-250 ft lb $389
Truthfully, I think they both have a place in your tool box. It comes down to what you can afford. I would NEVER cheap up and get one that doesn't click. Check CraigsLst for a deal. There are a lot of tools on there.

BYW, I torque almost all of the bolts that I put on a tractor if there is a seal involved. If there is no torque spec in the book there are tables on the internet that give the standard torque for a grade 5 and grade 8 bolt.
 
I have owned three or four Snap On meters and click types, the most accurate is the 19.99 Craftsman beam type. Don't tell anybody what you use and buy the cheap one, you will have more money in your pocket and still have the right torque.
 
A straight extension will not affect the torque settings. If you use an offset extension the torque settings would have to be recalculated to correct for the offset.
 



Go check something where torque is real important, like aircraft repair. There a torque wrench is required to be calibrated every so often, like rapid temp changes, 90 days or if the wrench is dropped. When was the last time any of us had ours calibrated? So basically we are getting even torque rather than accurate.

I use a Snap On 3/8 drive one. If it has to be tighter than the 200 lbs rating I use my German one........goodantight!

I cannot recall how many engines my dad rebuilt through the years and he NEVER used or owned a torque wrench. And he never had a problem except once and that didn't have anything to do with torque, he broke a ring installing a piston.

Last summer i had mine calibrated. I had to go see him for something else and brought the wrench. It was still on after ??? years.
 
At our local small airport there is an old mechanic that works on old Pawnee and Stearman ag plans doing rebuilds and dope fabric repair.
There are always guys standing watching and talking as Frank is working on an old radial engine. He uses a standard wrench and when he gets the bolt to the proper tightness he clicks his tongue on the roof of his mouth.
He doesn't do it to be funny. If he is talking when he gets the bolt at the proper torque he clicks his tongue and keeps right on talking.
We are all used to it. And he has never had an engine or seals fail because of a torque problem.

Thanks for the replies. I did a web search and found some reviews on Craftsman.Everybody who has a craftsman torque wrench likes it but some say they wont ever buy another one. Main complaint is a "lock ring that breaks". I don't know what that is but guess I may find out since I think I will get a craftsman.Use on a model A ought to be light duty for the torque wrench. I will just have to be careful using it.

I would guess it is the lockring that holds the head on. Right where the 3/8" square is. Will Craftsman repair it for you if it does break? I know they are getting pretty stingy on their repairs.
 
I have two Proto click type torque wrenches. One 3/8" and one 1/2". I use the 1/2" the most because it is good for 120 ft/lb. The 3/8" is about 300 in/lb (25 ft/lbs.)

Good luck!
