This is my first purchase from military fasteners and won't be my last. Fast shipping and they have everything you can imagine for your aircraft needs. Thank you Military Fasteners

I would not change a thing. You folks have always supplied me with what I needed if you have it in stock (nobody has everything). Delivery has always been good. I am glad you now have a store in Georgia since I live in FL. Makes things a lot easier and quicker than getting stuff from California. Keep up the good work. I have a few more things to order in the next few days too. Thanks.
