Must be an American standard. I can't find any outside the US and $15 shipping for a few magnets... sorry no.
I bought 100 for $12 free shipping. I understand the cost problems for hardware. It will work fine without. I used it several times before my magnets arrived.
I had the same issue with the TNNSER. I could not locate a place for single purchase of the metric half but. I had to purchase 50 of the screws and nuts. Set me back $30 including shipping. I now have a lifetime supply of magnets, flathead screws and nuts. Anybody need a set knows who to contact

I also will add a key of injector blades to the pass around in case some people on the list have never used an injector before.
