looking for a new torque wrench. what do you like, click style, digital, what brand ? thanks bob.
I think a lot depends on what you are going to torque. For things like rocker arm stands the smaller SnapOn digital is great. For rods and mains you need the longer click stop SnapOn so you get more leverage when laying under the car same with the one for the heads you need the long SnapOn click stop
do you ever get your wrench calibrated . who do you have do it?
Usually the manufacturer. I know some of the tool trucks have a device for checking them.
I have both a snap-on 1/2" and a 3/8" digital, love them both.
thanks for the replies. still using my old Blackhawk but it hasn't been calibrated in over 40 years. think I'll have to chase down the snap-on truck next time he's in town.
Calling the Snap On guy is like feeding a stray dog, once you do you can get rid of them.
Make sure your wallet is full, it won't be after you leave...….
You get what you pay for $$$ but how much do you spend on that motor.
That's why I have the Snap-ons………………...
Buy CDI torque wrenches, they make them for snap on and I believe they might own them now. Not cheap but cheaper than the tool guy or buy them used. I use a torque wrench calibrator and have it calibrated once a year by “Team Tourque”. It is about what your are doing .So,if you can stretch the bolts and measure them and have specs do it. If not, head nuts etc use a calibrated wrench
thanks i'll look at cdi
Make sure when you buy any brand that it is already calibrated . I know it doesn’t make sense , but some brands add not calibrated ....go figure .
I get mine (Snap on ) calibrated every two years
All my torque wrenches are Snap on ( click type , non digital ) and I have the dealer check them on the truck a couple times a year. Keep in mind as you get older it is harder to see the numbers on the wrench if you are not in a well lit area. I will probably switch over to the digital ones.
I have always liked the Matco torque wrenches over the Snap-On's.
The Matco has a break over movement when you reach the torque value where the Snap-On has more of a solid click. Just for me it feels easier to stop on the desired torque value with the Matco.
Not a fan of digital torque wrenches. Just a bad personal experience. Had a snap on go bad torquing heads years ago. Nothing like feeling the stud stretch instead of a click or beep.
I do all my torque wrenches every year. The normal calibration points are minimum setting, 60 % and max setting.
The only one that is more than 4% off are the snap on long handled 1/2 for mains and heads.
Based on the calibrations I have done there is no correlation between price and the accuracy of the torque. But does the torque really have to be within the 5% or so considering lubrication, thread quality etc.
I think the most critical torque is on the rod bolts. You can probably be ok at 5% over but dangerous at 5% under. That’s not based on and scientific data just a WAG
I know of someone who was having on going issues with Rods and Head gaskets. He was using an old non -descript Torque Wrench that he would also use for turning over the motor (blown)..... an "investment" was made in a good calibrated torque wrench only to be used for its intended use and a long ratchet to turn the motor over.
RESULT= Virtually eliminated his issues.
all good info. thanks all
