It will probably cost me around $400 but working with a nice tool is a reward all in itself. We've had a lot of calibration issues with the Proto brand in the past - I've been told by my Proto representative that they are much improved but I'm still planning on spending my money on a Stahlwille wrench. Snap-On's standard line of click type wrenches are 4% accuracy tools - the TQ series wrench is a pretty good one. Precision used to make some of the torque wrenches for Snap-On - very good wrenches - but I understand that they don't do it any more - Snap-On was going through some management changes and the orders were too irregular so Precision dropped the Snap-On business. The Snap-on Techwrenches with the flex head ratchet are 2% accurate (1% in the memory models - but only a production shop where you need to record the torque settings would require those) - These are nice tools. They also make some dial type wrenches (the 71 series) and some great torque screwdrivers. The new Stahlwille 730N series of torque wrenches are the ones I was talking about - they are a 3% accuracy wrench - more info here: I'm planning on buying a Stahlwille wrench myself - actually I need two - one for torque up to about 50 ft-lbs (or whatever the equivalent is in n-m) and one to go up to a little over 150 ft-lbs. The factory rep likes to demonstrate the durability of the tool by throwing it across the room. We also use a lot of Sturtevant-Richmont tools - they hold their calibration well and are relatively easy to calibrate.īut the absolute best torque wrench I've seen is the Stahlwille brand made in West Germany - they have a ramped block design that makes calibration incredibly easy, there is no spring to lose its tension if the wrench is not returned to zero and their calibration interval is longer than any wrench we use. We're using the new electronic wrenches on the F-22 and they are working fine - probably my second choice in torque wrenches. the Snap-On wrenches are very, very good. I've been doing this for over twenty years so I think I know good tools when I see them. Ten highly configurable presets with the ability to customize numerous functions (sleep mode, LCD display, calibration, etc.I'm the tool engineer at Lockheed Martin that decides what torque wrenches we buy to use building F-22 fighters and C-130 cargo aircraft.Protected end cap design with solid brass contacts prevents accidental loosening and ensures continuity.Low-profile buttons protect against accidental activation.Unique design offers a streamlined shape with a knurled, non-slip grip-important when working in oily/greasy environments.Cycle counter to ensure how many fasteners have been torqued.Flared end prevents your hand from slipping off during high-leverage applications.Textured grip offers a comfortable, non-slip surface.Torque-then-angle allows the user to torque fasteners and then switch to angle without removing the torque wrench from the fastener.Dual progressive LEDs allow user to see active torque at various work positions enables user to anticipate torque and slow down as they get closer to desired torque level.Six measurement modes (ft-lb, in-lb, Nm, Kgcm, dNm, angle).Angle Accuracy: ☑% of Reading, ☑° Angular Velocity >10°/Sec Torque Accuracy: ☒% CW and ☓% CCW, 20–100% of full scale.Provides a wide working range, 30-600 ft-lb which allows technicians to work on a wider array of popular applications.
