Durofix RM602-4A (25 to 250 ft-lbs.) Digital Torque Adapter with Buzzer and LED Flash Notification – ISO 6789 Standards with Certificate of Calibration

This is perfect for doing angle for head bolts and crankcase bolts. As long as you're starting torque is 25 ft lbs or more, then you can use this and it makes it so easy!Batteries going out will happen. Get some higher quality cr2032 batteries. May have to undo one bolt, re torque, then do angle again if this happens.I recommend this over an expensive digital torque wrench and those terrible angle gauge toys. Unfortunately for me, I have a warped head in my case, but this makes things easier when I do again soon.

Quality item. Arrived in good condition.

The media could not be loaded. I can not confirm accuracy but it come with calibration cert. Can be set to about 4 or 5 different units of measurement. Track or highest reading settings. I'm keeping it. Time will tell it holds up.

Right off the bat, the batteries are toast. Unit wouldn't function. Bought new batteries. After waiting for this thing to power on for a minute i figured out you need to set it down because it's trying to do some calibration. Each time you power it on it does this. Compared the torque alarm setting to two calibrated torque wrenches and it changed wildly +- 30ftlbs each time it was powered on. The only reason i bought it was to use the angle function. Guess what else is wildly inaccurate.... Not to mention it auto clears the measured peak angle in under 10 seconds. So if you are working in a tight area and need to pull it out to check it, then go back to complete the angle, odds are you will be looking at a new reading from what it thinks is zero. They should be paying us for wasting our time with this junk.

Much easier to use than the dial angle tool for torque to yield bolts. It does regular torque measurement too but I have several good torque wrenches so I haven't used it for that

Never could set angle meter on original meter purchase. 0l

This device permits simplified torque measurements to fasteners without the need to employ harder to apply torque wrenches. The device simply is installed between a ratchet handle and any 3/8 socket. It’s simplicity will make it a frequently used accessory when replacing bolts requiring critical torque as specified in their installation.

Very accurate and semi easy to use. I like that I can use on a shorter ratchet for oil drain plugs. Works like a charm for 200 ft pound weight distribution hitches down to 33 lb oil drain plugs without having to get three different torque wrenches.
