The EZRed MR34 Extendable 3/4″Socket Wrench is a Beast With Two Quick and Easy Tweaks

I have both SAE and Metric 3/4″ socket sets that come out once or twice a year when I am working on big bolts on cars and trucks. As you may know, the longer the wrench, the more torque you can apply. Back when I was younger would would slide a piece of pipe or heavy wall tube over a ratchet or breaker bar to get even more mechanical advantage. We definitely snapped some socket wrenches while doing this as we exceeeded their design specs.

You see, a ratcheting socket wrench has limits as to how much torque the mechanism can handle before something either bends or breaks. Quite often, the rathchet pawl would bend/crumple and no longer be able to engage the teeth of the gear. When that happens, we’d toss the cheap wrench.

This is why breaker bars were made by the way – they have no ratcheting mechanism and, thus, can handle more torque. There’s one problem though, there are times where you can’t get the breaker bar into position because you can’t turn the handle relative to the socket. So, what is a person to do when they need a ton of torque and a ratchet mechanism?

The short answer is to get a wrench with a long handle that is designed to handle a ton of torque. A ton of companies make socket wrenches with longer handles. I have a couple of these but what I find really handy are wrenches with extending/telescoping handles. When you are working in a relatively tight space, you may not have room for the fully extended handle or you have need to work it into position before you can open the handle.

The EZRed MR34 Wrench

So, when I need a ton of torque and mechanical advantage to help me get there (I’m at the age where I need to work smarter because my body doesn’t support harder any longer 🙂 – I break out the wrench I affectionately call “The Beast”. It is a beautifully made and chromed giant 3/4″ ratchet wrench.

The wrench is sold in the US by a firm called “EZRed” with a lifetime warranty and, like many things, is actually made in Taiwan. When you do some digging around, there are a lot of guys using this wrench for heavy equipment, farm equipment, trucks, steam pipes and more. After reading about the real world experiences with the wrench, I ordered one in.

Here is the wrench closed and you can see it is about 24″ overall.
Here is the MR34 fully open and about 40″ long overall.

The first things I noticed was that it’s a big wrench even without the handle extended. Next, it’s a heavy wrench and weighs in at about 8.5 pounds. I have to be honest, I don’t usually pay much attention to looks but the chrome finish is gorgeous.

Pull the collar down and a detent is released that allows the handle to telescope out. The handle then locks into position in the next available hole. The locking feature is definitely nice.

I use this for 3/4″ sockets and also have a SunEx 3/4 to 1/2″ reducer for those times I want to apply a ton of torque to a smaller bolt.

Here’s the wrench with a SunEx 3/4 to 1/2″ adapter.

So far, I am very happy with the wrench. As you can tell, I haven’t used it a ton yet but for the few quick jobs so far, it worked great.

Two Big Tips

A fellow recommended apply Blue Loctite to the head screws and grease the wrench while it was open. He was spot on – the screws were surprisingly lose. Even though they have blue thread locker on them from the factory something seems odd and guys have reported losing the screws. I really think if Ihad not followed the fellow’s advice I would have already lost mine as well – they are that loose.

The screws come out and then the head is very serviceable. You can see the two pawls and their springs plus the selector in the middle. What you don’t see is any lubricant! I must say I am a bit surprised.
You can see the faceplate and the 24 tooth geared head.

So, I used a brush and lightly applied SuperLube grease to everything, reassembled the wrench and put Blue Loctite on the two head screws before tightening them down. The whole thing took maybe 10 minutes start to stop including taking the photos.

If you ever need it, the EZRed sells a rebuild kit – part number RK34.

Summary

I really like the wrench. It’s worked great so far but I really haven’t done anything super stressfulso far – just breaking some very rusty 1/2″ diameter carriagle bolts free off my plow. It’ll definitely get used this upcoming summer a lot more.
