After trying this extensive set of fasteners, Im amazed. It comes with everything one could need for any project big or small, and is of great quality... The variety of screws, washers, and gaskets is impressive and the case it comes in makes organization easy. The sturdiness of the fasteners ensures no stripping or stretching occurs. One minor downside was that some of the pieces were difficult to remove from the case. Overall, a great investment for any industrial or scientific setting..See full review
