The customer service from Trisha Hawkins at Military Fasteners was exceptional.

5.0

I've been a customer since 1983 and you have provided what I needed most times in a very timely manner at the right price. Over all I have been very satisfied with your company.

5.0

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.

5.0

My many experiences with Military Fasteners have been very good.
