Great Vendor. They worked with us, A+, 100%! Will do business in future. :)

5.0

As always great service with fast shipping. That's why I always choose military fasteners first for my aircraft needs. Thanks.

4.0

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

Really fast processing of my order and faster than expected shipment and delivery. Really pleased. Thank you.
