This is my second order. My first order was delivered quickly and was all it was described to be. I am confident from seeing and using the #8 screws that my new order for #4 and #6 screws will be equally pleasing. The #8 screws and driver bits are beautifully made and I felt proud of my work with them installed. - Dan
The fasteners were made with very high quality bronze . I will order again
The drill bits I ordered didn't arrive as scheduled, so I let Fair Wind Fasteners know. They immediately resent the same order so that I received it within a day or 2, and the first order still should be arriving sometime. It’s great to know about a company that stands behind its products & service as they do!
High quality product, delivered fast. Couldn't be happier.
Very good service!
