ACDelco ARM602-34A 3/8” & ½” Heavy Duty Digital Torque Adapter Combo Kit with Buzzer and LED Flash Notification – ISO 6789 Standards with Certificate of Calibration

These were exactly what I was looking for. They work great with my ratchets of pry bar. I’ve used them for torque the bolts on flywheels, oil pans, and full motor rebuilds. I would highly recommend.

Really easy to use, no need to keep the instructions handy, they are easy to set up. A must have if as in my case, space for regular torque wrenches if an issue, and cheaper too.

So I purchased the set of both the 3/8 and 1/2 torque adapters. They seem to work great however I was disappointed at the minimum torque range for the 3/8 with a lower limit of 74 inch pounds. I would have liked it to be more like 30 to be useful.

I've already used these multiple times doing auto and motorcycle maintenance and they are so much more convenient than my manual torque wrench I was using and the accuracy is right on. Also like the benefit of the visual leds and audible notifications when you get close and to final torque.

This item works as advertised.

I'd been on the fence about rather these would be any good or not. Had been looking at full blown torque wrench sets but didn't want to take up that much space in my tool box or spend that much money. These are compact easy to toss in a portable tool box if needed, accurate, and easy to use.

I bought these to check the accuracy of my bar torque wrenches. They seem to read accurate. Good value for the price in my opinion.

This is a must for any tool box. I have used the standard large torque wrench for years, but with moving, tools hitting and at times tools hitting the floor I just can’t be sure the old style is still accurate. This is a digital read out and give the audio alarm when you are getting close and get to your poundage you set. It can easily be switched to in/lb and newton’s. These make any breaker bar or ratchet into a torque wrench.
