Wheel bolt confusion

I've sent the same question to the supplier, but asking here in the hope of a quicker reply.

I bought some spacers which came with extended wheel bolts, but looking at the head of the bolt I am not sure they are correct.

Stock wheel bolt


Supplied wheel bolt


From above, it's clear that the 'flange' is a completely different size when compared to the 17mm hex head on each bolt. The seller has assured me that these bolts are the correct M14 x 1.5 R14 fitment.

So my question is, are these bolts correct or is one of the measurements wrong?

its possible that the ball seat doesnt extend as high as the stock one so it will appear smaller even though radius is still fine. mount it up to wheel drive around a day then take off, you can compare the contact area wear to the stock bolt to confirm.

Thanks. I guess I will give them a try... Any idea which measurement of the bolt with diameter of the flange is?
