Video Transcript for Powerbuilt 12 Point Socket with 3/4 Inch Drive Review

Today we'll be taking a look at the Powerbuilt inch-and-seven-eights three-quarter-inch drive socket, part number ALL643216. This socket is ideal for tightening down hinge balls to ball mounts, or weight distribution heads. It's a three-quarter inch drive, so you need to be sure that you have a three-quarter inch drive torque wrench, or an adapter. It's a twelve point oversized socket, and it's built to exceed tool standards. This socket features a lifetime warranty. Now let's go ahead and show you how to use it in a typical situation. We've got our weight distribution system here and we need to torque down our ball.

In order to gain access to it, we're going to go ahead and flip it over, so we can gain access to the nut. As you can see, putting a pipe wrench down there, or any other type of wrench, would be virtually impossible. That's where this socket comes in handy. Lets go ahead and drop the socket in, make sure it gets situated. Then we can take our torque wrench and put it into position.

We'll want to set the torque wrench to whatever our manufacturer recommends for our ball mount. Now we can immobilize the other side of our ball, and begin torquing. If need be, it's not a bad idea to get an extra set of hands to hold your other wrench. Looks like we've got it. Now we can flip it over and continue setting up our weight distribution, or, if this was just a standard ball mount, we'd be ready to tow. That's going to complete our look at the Powerbuilt inch-and-seven-eighths socket with a three-quarter-inch drive, part number ALL643216.

1-7/8" 12pt Thin Walled Socket - 3/4" Drive - Chromium-Vanadium Steel - ALL643216

Average Customer Rating:  4.7 out of 5 stars   (178 Customer Reviews)

1-7/8" SAE thin walled socket with a 3/4" drive should be used with a compatible socket wrench (sold separately) to apply torque when installing a hitch ball on a ball mount or weight distribution head. Steel construction resists corrosion.


This was supposed to be a thin wall socket needed to torque the hitch ball on the equalizer hitch system. Outside diameter of the socket is too big And did not work.Luckily I was able to find a shop 20 miles away from me that was able to mount the hitch ball and torque it correctly For a fee. Wish I would’ve save the money on the socket to go towards paying to get it done.

I reached out to the manufacturer and they have not had consistent reports of this socket being incompatible with Equalizer balls. Equalizer does make a socket that is made for their WD systems. It is part # EQ70-00-4800
Thin Walled Socket for Equal-i-zer Hitches
. It is important to use a ratchet with a three quarter in socket for installation.
-- Etrailer Expert Jenny N - 02/04/2022


The socket is too big for the "thin walled" socket required for the equal-i-zer 12k hitch installation. Unfortunately I don't have another need for a socket of this size.


Review for the thin wall 3/4" drive 1 7/8" socket. This was needed for torquing a hitchball to a weight distribution head. The thin wall was just narrow enough to slip onto the nut down in the head. It was snug but came off after torque was set with abit of care. If you have a tight work space such as l did on this application, you must use a thin wall socket. Product appears quality & should last yrs. 5 stars for product & timely shipping from etrailer...

One year update. After using the socket for the last year to check torque, all is as l would hope. No problems using to keep a check on the 430ft pounds required by manufacturer. Looks new. Has a good finish on the socket. No rust marks anywhere. Expected to last years with care.

Works great for installing the ball on hitch head.


Socket had the right height to fit between ball nut and hitch frame. Worked like a champ. Good communication with company informing me of delivery. Will do business with etrailer on future needs!


It did fit in the Equal-i-zer hitch hole to tighten the ball. I don't know why they just don't make that hole larger.


Works well, although you cannot put the nut on first. The socket will not fit in on the E2 head. But if you put the nut in the socket and start it by hand, then torque it down, the socket comes out easily.


Worked perfectly for attaching 2 5/16 trailer ball to equalizer hitch.


This socket was specifically advertised to be used for tightening the ball bolt for a weight distribution hitch I purchased. But this socket did not fit. I had to cut the socket short so it can fit. It’s a good thing I had the right tool to make this cut (a metal band saw). Before purchasing, take a close look at the dimensions and make sure it fits in your application. The socket worked perfectly after the mod.


I have always received great service from the etrailer. Thank you Halle and all the rest of your staff for their excellent performance. Timely shipping and great products!

I dont use it very often but it gives me plenty of peace of mind knowing that if the hitch ball loosens I have an excellent socket to bring it tight!!
Bruce - 07/19/2021


Socket is affordable shipped quickly quality made

I’ve only used it once. So nothing has changed. Still quality. Sitting in tool box collecting dust
Thomas - 08/30/2022


Socket worked perfect on my Equilizer brand hitch ball installation. Excellent Quality.

Great socket, works perfectly on my equilizer hitch ball. When the socket is not in use it makes a great workbench decoration and talking piece.
Wayne S - 12/06/2021


Used once for our hitch, never used again. Worded as it should and was responsible priced.


Gave it four stars only because I ended up not using it. Quality looks good. Kept it if needed for adjustments.


Torqued like a champ!

Excellent. Glad i bought it!
Michael S - 08/22/2022


I have had the socket for several months and it is working great.


I have had nothing but excellent service from the etrailer. I first ordered parts to upgrade my old equalizer hitch with Clips. They were shipped fast and everything just as ordered. This has been a great upgrade for me. Instead of using pens the clips make it a lot faster to hook up and unhook.


Amazing quality and worked perfectly on my 14000 lb Equalizer Distribution hitch.. was a 60 second tighten, and was worried this thin wall socket wouldnt fit (silly me)

I purchased a 24ft 3/4 drive torque wrench and that did the trick.

Definitely keeping this aboard on my travel trailer.

Great! This is a lifetime part. After pulling my TT 6,000 miles if only had to tighten once using this product
Jason S - 03/21/2020


Nicely made very strong socket, I've abused it on a few occasions on a large 1300lbft impact wrench and it shows no signs of failing. Very happy with the purchase


Fits the Equalizer trailer system 14,000lb hitch ball bolt perfectly inside the Equalizer hitch head!

And who doesn't like "perfect" with a $40 savings over the Equalizer socket price.


Have pulled my 12,000lb toyhauler over 8,000 miles with the new ball and Equalizer system and some of the highways got surprisingly rough with no warning, which really took our rig on a bit of a roller coaster ride a few times but the ball and hitch system worked perfectly. Still like my purchase after putting it through some real world conditions.
Jack - 04/05/2020


The 3/4" drive 1 1 7/8" thin walled socket was just what I needed for my Equal-i-zer hitch. It was also the best price and fast shipping. My thanks go to etrailer.

I have no problems with the socket after using it several times in the past year. It works very well, and is worth the price.
RonW - 04/14/2020


I bought to tighten the nut on my hitch ball on my Equalizer hitch head. After moving the bar receivers out of the way, this socket fit on perfectly and I was able to snug it up. So glad etrailer offers this socket.


Just as needed. Good fit for Equalizer hitch head ball. Thank you.


Drawback of weight distribution hitch was loosening of ball on hitch. When connected, unable to notice loose nut. Now able to make regular checks before traveling.


Just what I needed to attach a trailer ball to by new equalizer hitch -- it's needed because the nut is recessed within the hitch.

Ball stayed tight from NY to TX and back. What more could you ask for!
