Powerful Astro Pneumatic Tool RN8M: 100-Piece M8 8mm Steel Rivet Nuts for Ultimate Fastening Efficiency Review

Using this product, our team found that it was incredibly effective in getting the job done quickly and efficiently. The nails were sturdy and held up well under pressure. Not only did they work well, but they also came in a handy container for easy storage. The only downside was that they were not as sharp as some other nails we've used in the past, so they required a bit more effort to get them started. Overall, we highly recommend these nails for any home improvement project.

6 of them tested on a piece of sheet steel and all 6 are installed correctly and pass the 25Nm torque test for M8-1.25 threads. Tip: Even if they are steel, you can successfully install one or more with an M8 bolt, washer, nut and 2 box wrenches. You don't need superhuman strength either. A good alternative if you don't have room for huge installation tools or just want to install a few. Just practice a few times on a drilled piece of sheet metal.

This is very cool! For size 8mm I drilled a 13/32 hole and hammered in the insert. (Also tried a 7/16 hole - still works, but harder to roll the insert because it wants to wobble.) One 8.8 bolt inserted with a thrust washer - https://www.amazon.com/ dp/B00JQ26HSW/ref= cm_cr_ryp_prd_ttl_sol_6 --under head and folded liner up to 26 ft lbs. It appears that attempting to tighten more than 28 ft-lbs will cause the insert to lose traction and start spinning.
