I was looking at the lateral box section behind the bumper on my 931. Is the material thick enough to drill and tap for small machine screws? I am trying to avoid welding on a mounting bracket. No skills, and no welder.

Thanks!

Anyone ever used these:

Looks kinda like a crappy hollow wall anchor.

How about these:

Looks a bit more sophisticated, eh?

Sorry about the "eh," I've been (pronounced "bean") in Canada for days, buddy!

I've used Riv-Nuts, they work very well. I do use self-tapping screws on the sheetmetal, but only for very light-duty stuff - electrical ties, hoses, extinguisher plumbing, etc.

One difference between the wall anchor and pop-nut designs is the pop-nuts are alumin[i]um, and I'm pretty sure the wall anchors are steel. -Just in case that matters any.
I have a set of the pop-nut style - they work well. Whichever you go for, I'd use anti-seize on the threads. Otherwise there's a good chance the screw will become rusted to the nut and the whole thing will spin instead of unscrew come removal time.

Do you still have that huge windshield washer tank hanging on the passenger's side? Might be a good spot for a large pump.

I have used and sold the nut sert style inserts and they work great. They have been holding my skid pan in for years. They make a large flange version that sticks up a bit more but with the larger grip area , it's very strong and the hole does not have to be perfect .

Any suggestions for a supplier? A special tool is needed to install them, right?

Apparently, the Marson tool from JCW uses both alumin[i]um and steel "thread serts". The "nut rivets" for the Pittsburgh tool from Harbor Freight are aluminum.
