I used them to make a special short travel shifter for my Mazda3. They fit perfectly with the factory shifter cable ends! They've been working great for a few months now!
These studs work great with some ECCPP bonnet stays. They are used on my Toyota Supra 88, the size and thread pitch are a perfect match. The 10mm bullet size is also perfect for ECCPP (I don't know about standard posts).
