Rivet Nut Mandrels Set, Including 6-32 8-32 10-32 and 30 Rivnuts, Rivnut Tool Replacement Tips, Expanded Mandrels Kit for Nutsert Tool

I needed an #8-32 mandrel and found this handy set selling for a good price. It's compatible with my Astro Tools nut setter.

About the Giantisan rivnutter, and it came with a good assortment of mandrel/setters. It States both in the manual and on a sticker prominently added inside the tool kit casing that these three mandrels have to be ordered separately, and I found out why. The hard way.If you are using these mandrels, they are smaller, and more delicate than what comes in the main toolkit. Therefore, you can't really crimp by feel on these.. you have to really pay attention to the linear stroke on the gauge built into the tool.If you don't set it up and calibrate the stroke correctly, you can break the tiny little 6-32 mandrel as I did. I have also considered that it could be poor metallurgy, but it's more fair to say that it was most likely my own mistake instead. The Dual handle rivet setting tool is a real hoss, and I could easily see why it overpowered the tiny little 6-32 thread gauge on this mandrel due to poor calibration.I was only 7 rivets into a ~300 rivet project!Fortunately, there is another store on Amazon that offers a pair of 6-32 mandrels that fit this tool for a fair price, so I did not have to purchase this entire three mandrel set again.I have received the new replacement pair of 6-32s, but have not been able to return to the project yet. I will soon though, so I will add an update here if necessary!Take heed, and fully read the manual of the rivetting tool before setting up these mandrels. I can't emphasize that enough.I do not fault Giantisan for my troubles, just my own ignorance. But I'm learning!

Dad used it, so must have worked.

Very satisfied with the rivet nut mandrels, and would definitely buy from this seller again
