I have been an Military Fasteners customer for more years than I can remember, and have NEVER been disappointed. This order is no exception.

Best order yet. I build masts for RC sailboats and perfect stock is a must. Whoever picked this order outdid themselves. Thanks Military Fasteners for another order of great material.

Fast, efficient, knowledgable, good all round people and I will be doing more business with them. I have an older plane and it is needing some refinements. Thanks for your service!
