Perfect if you're after metallic cheese!

Compressed spray painted cheese! I have never worked with such soft easily destroyable ""stainless steel" bolts before. Doing a small project I have sheered off the heads of several on a really low torque setting of my driver. And the philleta keys chews away if you look at it too hard! Honestly never had such a bad set
