Customer Reviews

My orders have been delivered on time or earlier all packaged well and in good shape. Thank you Military Fasteners.
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.
As usual you guys did an excellent job , fast delivery and all the items in perfect condition. What else could you want. Thank you Military Fasteners.
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.
