I'm looking to get an assortment of spare grease fittings. I have some SAE ones but no metric ones. It looks like most large metric sets come with 6mm, 8mm, and 10mm sizes. Is there one size that's used the most? I would rather not have 50 fittings that I'll never use sitting on a shelf collecting dust. If 6mm is used through out then I'll just buy a couple of 10 packs of straight, 45, and 90 degree.
