Source for Hex Rivet Nuts

I've been hunting around for hex rivnuts to fit the hex punchouts in the Promaster cargo area. I think these punchouts are designed for rivnuts for metric M8 machine screws with an inch measurement of .431 across the rivnut flats. Someone on another thread was using 3/8-16 Atlas rivnuts that were .437 across the flats which seemed to work. The only problem is the clamp range is something like .104 to .225 which would leave a rather sloppy fit on the thin sheet metal of the van.

I found the same 3/8-16 Atlas rivnuts but with a .030 to .115 clamp range which is much better suited for our purpose. The part number is AES37H115ZYR. They are available from DB Roberts for about 51 cents each and they ship out of their New York warehouse. DB Roberts sales is 800-800-6887.

I believe that they also have the thin head version of the M8-1.25 rivnut with the proper .431 across the flats in stock as well. I don't want the thin head, but if you think it would work for your purpose, the part number is AETHHS-M8-3.0ZI The clamp range of these is .5mm to 3.0mm which is perfect for us.

I wanted the full head version (part # AEFHHS-M8-3.0ZI) which is out of stock in the M8 size and requires a minimum order of 150,000. Hence I went with the 3/8-16 which has the proper clamp range as well as the full head. It's about .006 oversized across the flats but should work.

Forgot examples of the thin and full hex rivnuts. The photo with two rivnuts is the thin head version. The single rivnut is the full head version.

AES37H115ZYR Full Head 3/8-16 In stock .437 across flats No minimum from DB Roberts
AETHHS-M8-3.0ZI Thin Head M8-1.25 In stock .431 across flats No minimum from DB Robers
AEFHHS-M8-3.0ZI Full Head M8-1.25 Out of stock .431 across flats Min order 150,000

All the above are Atlas part numbers with a clamp range of about .030" to .115" or .5mm to 3mm.

The McMasterCarr 3/8-16 rivnut has a clamp range of .104-.239. This would be optimum for 1/8" to 3/16" thick metal for a good snug fit. The thickness of the metal in our ProMasters is around 1/32" or a bit less, hence the rivnuts listed above which are a much better match.

None of the other hex rivnuts listed fit the Promaster hex punchouts.

Thanks for doing the leg work on this. Can you report back with how they work out for you?

Charity, The problem is not finding the proper rivnuts for the Promaster, but being able to purchase a reasonable quantity. If you'll notice, BaySupply has a 500 minimum order. Same goes for Fastenal. You'll find the same issue going directly through Pemnet. It was Mary Jane Davis (inside sales rep at Pemnet) that directed me to DB Roberts as a source for small quantity orders, and gave me the minimums for direct and/or out of stock orders.

It would be cool if Hein could stock these. 500 at 20 cents each would be reasonable if you were in the market to resell them with a good mark-up. That's what DB Roberts is doing. They purchase at 20 cents (or less) and resell at 50 cents. They just don't carry the full metric line. McMasterCarr is also doing the same thing but they charge 68 cents each. I would have gladly paid the 68 cents, but the clamp range they carry is way to large.

If anyone wants to retry Fastenal, they can supposedly order these from Bollhoff, (Rivkle rivnuts part number 2334 1080 230). These are made in France. I have talked to Bollhoff sales rep here in Canada (there is Ballhoff USA), they do not want to sell directly, but she claimed they deal with Fastenal on regular bases and their (Bollhoff's) minimum order is $50.00. My local Fastenal is kinda small and unfriendly and I didn't get anywhere with the guy. It might depend on given manager. I am not desperate for them, but might try again somewhere else...

I looked at Jay-Cee Sales half hex rivnuts and couldn't find the right size. The hex cut in the promaster is metric 11mm across the flats which is about .431 inches or so. Jay-Cee's half hex rivnuts are either .375 (9.5mm) which is to small, or .500 (12.7mm) which is to large.

Maybe I'm missing something?

Got the AES37H115ZYR 3/8-16 hex rivnuts from DB Roberts yesterday evening. They fit the hex punchouts in the Promaster cargo area perfectly. I ordered 50 at about 50 cents each plus a few dollars shipping.

These are the same Atlas Brand from Pemnet that are sold by McMasterCarr only these have the .030-.115 inch clamp range for thin sheet metal 1/32"-3/32", where McMaster only carries the .104 -.229 clamp range best suited for 1/8"-3/16" thick metal.

Specs look very good indeed. My local Fastenal insisted on a minimum of 450! :eek: Hence I decided to look elsewhere. If you can get 25, that's a great deal. My dealings with Fastenal have been inconsistent at best. Sometimes they will work with me and other times they act like my small order isn't worth their time.

I just received these yesterday. They fit in the factory hex holes but I haven't used them yet. It took about 3-4 weeks to arrive from China. Thanks to SteveSS for finding them in the first place. I'm sure they have other sizes and shapes.

ShaunB, as much as I'd like to, I can't take credit. It was KilWerBzz that found them. I ordered and received some as well, but haven't tried them either. No tool yet. I did notice some hex holes under the van too. I might use some when hanging the grey tank.

Anyone try these from Graingger?

0.685" Steel Hex Rivet Nut Rivet Nut with 3/8-16 Thread Size and Zinc Yellow Finish.

Grip range is good but the rep on the phone couldn't tell me the distance across the flats so I just used the ones from McMaster Carr. Pinched in just fine even though the grip range is larger than our sheet metal.

To the OP: I couldn't get to the description of the rivnut on the DB Roberts website. The site found your part # but no description or price. It says you don't have to login but do you think you do to see the description?

The part description says 1/2 inch hole. This is the dimension across the flats. You'll find it is too large to fit. You need 11mm which is .432 or so across the flats.

PopeAng,

email me I have some (contact info on my website in signature)

ivan,

If you google "rivnut tool" there are lots of videos on simple homemade tool ideas, and they work!

To install my hoop steps, I used a simple metal bar setup.. worked well.... and you don't have to search for an insertion tool with the right metric thread, just use a strong bolt.

The metal bar was an extra piece from a garage door opener kit. A little oil on the double washers under the bolt made it work smoothly. Good for tight spaces (like under there) but also easy to use along the van rails with hex nuts inside!

I can also vouch for the metal bar "tool". It's super easy and doesn't cost $50-$100 for an official "tool". It also doesn't require 2 sets of wrenches like some of the other rivnut DIY tools you'll see or can buy.

I didn't realize what you were initially showing with this picture because it's *too* easy - it seemed like it should have been more complex! Use a cordless impact wrench to tighten and it's even easier.

Here's a video of a guy using the same setup:
