Very good service, as usual. Order was complete and correct. It is easy to order on your website and the deliveries are always in the specified time.

Jasmine is great! Very kind and helpful. My parts came in EARLY and shipped the same day I ordered!

5.0

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.

Fast, friendly and professional service that only Military Fasteners can provide with every order that I have placed with them.
