Durofix RM604-4A 1/2'' Digital Torque Adapter, 25-250 ft-lbs, Max 720° Rotation, Buzzer & LED Notification, ISO 6789 Certified with Calibration Certificate

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.

Very volatile, inconsistent, and unreliable item. Works sometimes and does not work sometimes. New batteries die while using it , and the readings are inconsistent. I bought this thing for angle torquing, but thank god I tested it before torquing cylinder head. I marked bolts with a marker at approximame angles, but this thing is never close to the anticipated angle.

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

I used it to measure 90° angles after initial torque specs tightening cylinder head bolts.worked great.setting it up was a little trickey.good addition to any toolbox!

Quality item. Arrived in good condition.

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

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.

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.
