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!

In this day and age, it is rare to be impressed by customer service however, Military Fasteners has far exceeded my expectations. They went above and beyond to help ensure an important package delivery on time, and they made a little boys Christmas sweeter in the process. Thank you to the team there for your wonderful help. I will certainly come back to shop again and again. They always say, fly people are the best people.
