Haven't had any problems so far and have used them a lot, the finish is good, the threads are fine, they don't seem to be made of the rather brittle metal compounds one usually finds in imported fasteners. However, I cannot say how well they survive outdoor use. If you use this type of fasteners outdoors or in the car, it might be better to go for the stainless steel option. Overall I recommend them as a good buy. Please let me know if you found my review "useful" or if you need more information. Thanks very much!
