I didn't realize this started as an old thread by another poster so you won't get an email alert to my reply of a few minutes ago further down. I was also just thinking, if you want to save money and are not in any kind of rush then you can order a couple of the proper flanged M12 x35 10.9 fasteners from China on aliexpress for under $7. That's all without having to drag your butt off your chair, delivered right to your home mail box by USPS, including shipping, exempt from customs brokerage and duty, plus a full no-quibble money back guarantee if it doesn't arrive in 60 days. I've bought odd fasteners that way on many occasions when I'm not in a rush. Some were metric fasteners I couldn't even source from McMaster. It would cost me more than $5 in gas just to go to a local fastener store to find they don't carry anything close. I can see a bunch of you rolling your eyes when you see China, but just where do you think these fasteners are being made and just where do think the likes of Volvo and McMaster get them? They come from the exact same factories, just by way of these massive small item distribution centers and taking advantage of ridiculously cheap international small packet delivery rates.
