We were very happy with our order. It was on time & exactly what we ordered. Thank you.

4.5

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.

Never had any problem since I began ordering from Military Fasteners for some time now! Always got what I ordered :)
