Everything arrived exactly as ordered. Online ordering was very easy. Thanks.

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.

Dependable! I KNOW that my orders with military fasteners will go out the same day and that the rare backorder will be shipped without my having to follow up.
