Dorman 743-100 Hand Rivet Gun

After reading some of the negative reviews, I was hesitant to buy this rivet gun. It's so cheap! Something MUST be wrong with it, right? NO. This is an incredible deal on a heavy duty, well made tool. It even comes with five different sizes of rivets (10 each), five different sized nose piece tips and a little wrench to change them out! I used it like many here, to replace a window regulator in my vehicle (2003 Mercedes ML350). The OEM Mercedes dealer rivets are Stainless Steel and need a powerful tool to install them. All four rivets went in with two pumps. The first set the rivet, the second broke off the shaft and ejected it into the catch cup. Every time. Super easy! The only reason I can come up with for the bad reviews is they were using the wrong size rivets in the wrong size nose piece. If you try to cram a large rivet into a small nose piece, I can see it getting stuck inside. But, if you pay attention to the sizes, and choose the correct nose piece, this gun works fantastic. I will admit that when I first got it, I couldn't find the extra nose pieces and thought they must be missing. Then after looking closer realized they are screwed into the handle on both sides! D'oh! At first glance they look like nuts holding the handles on. You don't change the entire nose piece, only the TIP! I wonder how many negative reviews were caused people not realizing this and using the wrong size rivets in the stock tip?

Worked great for what I was working on good quality at a low price

Looks well built, says CHINA in it in really big letters, not sure if that is a warning label….

Well, I bought it because it was Dorman, it worked pretty good done the job!! but it’s not labeled as Dorman, came with some miscellaneous rivets, which was nice

Five stars for an inexpensive rivet gun that worked right the first time out of the box. I had been looking for a riveter that could accept .25 inch rivets for automotive projects. Most of the others were nearly more than twice (and a few triple) the price of this tool. I can say with complete satisfaction that this tool just works. After placing the rivet the shank falls into the collection cup but only if you hold the tool with the head up but since most of the time I had to have the tool head up to place the next rivet it didn't much matter. Just a note, the tool is longer than most "gun type" rivet tools so closing the handles can be a a chore. I found that after the first closing you only reopen them until you hear the first "click" (as the jaws move down the rivet shank) and then close the handles. Repeat this until the shank breaks out of the rivet. Much easier.

Needed for a project and worked fine.

I used this with 1/4” steel shank, aluminum rivets, and it worked well

I purchased this rivet gun to replace some rivets in my car door for a window replacement. It did the job but if you were going to plan on using the tool long term multiple times you may want to look for a better US made option or a company with good warranty. I cannot speak on the long term durability of this tool as i purchased as a one time use product. It did the job and still works. Also came with a few rivets which was convenient. Handle is pretty large so this is not good for if you're working in a tight space.

Can easily handle 4.8mm stainless rivets, but I have found you need to select the mandrel one size up, to ensure the sheared pin will release and drop into the hopper.

There's only so much you can say about a rivet gun, honestly. There are five sizes of tips that you have to swap out, depending on the size of the rivets you're using, and the device works quickly. I've used the 'old' style 90 degree riveters before, and I have to say that this style is FAR more efficient. Dropped about a dozen rivets in my truck bed on the weekend, and they all closed up and snapped off in one motion. Really like the little catch can for the rivet stems. Saves having to pick them up constantly while you're working. The action on this is pretty smooth. If you use the wrong size tip, the stems CAN get a little stuck sometimes - but just giving the handles a couple of pumps (and screwing in the right size tip) should make it drop out. Glad I bought this one. Great price, works well for my needs.

I have bought other riveters that look just like this, but started to jam after about 50 rivets, so we ended up buying a new one every couple months. We use this out in the field a few times a week, and after over 150 rivets, its still working great. Collector cup is very handy to catch the used mandrels. Of all the others I've tried, the build quality on this one is the best. Will definitely buy again. If this one ever fails that is.

Good price compared to what the auto supply store wanted for a similar gun. Gun come with 5 different sizes of rivets. I bought 1/4 inch rivets because I thought the rivets never came with the gun. I used the gun to put 4 - 1/4 inch rivets on a window regulator. Worked fine but the only thing I don't like about it is you have to apply excessive force to break off 1/4 inch rivets.
