Does anybody know of a UK supplier of these please?

Hi

Have you thought about BSF anchor nuts instead?

Can only find UNF rivnuts: https://www.lasaero.com/site/products/article?id=O00DHQGIL (and a budget tool to fix them using a pop rivet tool: https://www.lasaero.com/site/products/article?id=T02UY0WNP)

Cheers

Bradford nut and bolt Co are worth a try.
I have had them from there.

A bodge, Ruairidh, which will, no doubt, upset some but if you can't find them in BSF sizes and you're not looking at securing anything that takes any significant load then once installed, you can run a 1/4" BSF tap down a 6mm Rivnut and a 5/16" BSF tap down an 8mm Rivnut creating a new thread in the BSF sizes. Not tried it with Whitworth threads but imagine it would work equally as well.

It won't upset them half as much as telling you I wouldn't bother with tapping. I'd just use 6mm and 8mm bolts.

Hi Ruairidh

UNC rivnuts are available which would tap out to BSW as same pitch for 1/4" to 3/8".

Ruairidh,
Hank nuts were original fitment in most floorplans and were fitted with 1/4"bsf raised head countersunk screwdriver slotted screws. I bought m6 Hank nuts from RS components, tapped them 1/4"bsf and made my own tool to fit them.
Hope this helps.

Genuine Rivnuts are still made by BF Goodrich in the USA & until the mid 90's by Linread in the UK. There are many copies around. originally they were Flange & Csk headed. Avdel introduced the Thinsheet Nutsert (which has a very small csk head & falls through the hole unless it accurately punched/drilled, but works in thin sheet material(!)& gives an almost flush finish without countersinking)These have been widely copied & are made by every far eastern man & their dogs with quality from awful to excellent. Mostly available Metric in Europe & UNC/UNF in the USA.
Look for them as "Rivet Nuts, Blind sheet nuts, Thin sheet blind inserts ....lots of variants. Thin sheet inserts have very thin walls & can be installed relatively easily with hand plier type tools. Rivnuts are much more heavy duty & are hard work to pull up by hand. They can be put in with a cap screw and a couple of nuts & a washer to "jack the thread up. In the 60's Landrover winches were held to the chassis as a kit using Aluminium 3/8 UNC Rivnuts and an illustration of how to do it with this method! More tricky with smaller diameters.
In the 70's Linread made over half a million aluminium Rivnuts a week! UNC/UNF/BSF/BA & even lots of Metric for Johnny Foreigner!

As a quick follow up Laser (who do induction heater kits!) also do Rivet nut kits, you should be safe with their eastern quality. Rivet Nut Co.uk may be worth a try as well

Thanks again guys.

I have various sizes of Nutserts, including the tooling, which I have been using successfully for a while now.

I have been searching unsuccessfully for bsf ones and decided to ask here. I will try tapping the 6mm ones as suggested, I appreciate you all sharing your experience.

Some years ago the power ststions here were using British generators & electrical equipment which used all BSF nuts & bolts.
Somewhere in UK is probably a lot of scrap generators etc. could be worth trying to track down.
