Trisha Hawkins over at Military Fasteners was friendly, speedy and very helpful for me as a buyer!

Military Fasteners is first on my list for the hard to find items so often associated with Government Projects. Brittany and Michael have always been quick to respond and nothing but professional in every way. I look forward to a continued relationship with Military Fasteners.

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!
