I have dealt with Military Fasteners a few times and they have always been extremely helpful and knowledgeable. Ramona has always been wonderful to work with and goes out of her way to help you find what you need. Definitely recommended!

Amazingly prompt response! I ordered over 1000 items and couldn't believe it when there was an email waiting the following morning saying the items had been dispatched. Easy to track the package online. By comparison I ordered some items from another supplier 3 months ago and I'm still waiting, with no apologies or communication emanating from them to explain the delay.
