Customer Reviews

Wow, great quick order. Website is easy to navigate and orders are shipped quickly. I have already passed along to others as having the right parts and quick shipping. Thanks, Danny S, Louisiana
I have always turned to Military Fasteners for all my aviation needs. They have never let me down and are totally trustworthy, fast and efficient. They have great choices from reasonably priced, to the best available. I've never seen the need to look anywhere else..Why would I..
Great product selections, reasonable prices and fast shipping....I don't know what I would do without Military Fasteners.
I was looking for hard to find parts for a safety critical application. The first couple of places I tried had the part on their web page but when I tried to order it they said, sorry, they did not actually have the parts. I called Military Fasteners. Talked to an employee without delay. She looked up the part number, told me who manufactured them (important), where the company is located (very important) and shipped the parts immediately from their own inventory. Super nice, helpful, efficient and knowledgeable. They get it.
