Rivet Nut Gun Tip, Riveter Tip Accessories, Spare Part (5/16-18), Replacement Mandrel

Good replacement. Didn't feel any different than the ones I got with My Astro 1442. People complaining about the mandrel breaking are either not careful when unscrewing it after riveting or do not have the head in proper position for the size they are working with. If you are using a smaller size screw like M5 or 10-24 your head needs to be set as low as possible so the Mandel isn't being pulled past the compressed portion of the riveting nut when you are at the end of the setting motion. You can tell your setting is off if you Ihave to apply a lot of pressure at the end of the compression. It's an easy mistake to make, and one I made myself, which is why I had to get my replacement. Once I figured out the correct setting on the head, the process of settling the rivets did not take a lot of pressure and the rivets did not look like they were crushed on the inside. Test it out and get the feel of the tool on scrap material before you start using it on your application. Good luck.

Bought to replace the one that came with my Amjoy tool that broke the first time I used it. It fot properly and worked as it should. Just be careful not to use to much force or you will break it.

Like so many other reviews, I to put to much torque on the first try and it snap. I purchased another one and so far it's holding. Make sure you are using the correct settings for this type of product.

My buddy busted the spot welded nut inside the floor pan for his subarus driveshaft center bearing. There was absolutely no way to nut and bolt it because the spot welded nut was inside a cavity part of the floor pan amd would require some serious cutting or welding. My cornwell nut setter kit only goes to m8 so I noticed this piece looks quite familar and went ahead and ordered it. Its the exact same part but also an upgrade to M10. This and the big kit full of fasteners had the driveshaft bolted up to 40 - 50 ft lbs within minutes. What a deal, very happy with no tool man prices or waiting weeks

popping the head off the crimper is pretty easy. These allow you to keep going and just toss that bad one.

Got the tool replaced immediately within 2 days

Had an issue with the item shipped. They resolved the issue immediately and replaced the part with no hassles, allowing me to complete my project utilizing the replacement tool part. Would definitely recommend utilizing them in the future.

Quality tip, however you must be careful with how hard you torque the rivnut gun as with the smaller bolt size the tip can break.
