Recently my avionics technician and I were installing a component in my aircraft and there were some critical fasteners missing from the manufactures package. This stopped the entire process. I called Military Fasteners after finding the parts on line, and Trisha answered the phone. I told her the situation and that I needed them ASAP. I found the parts gave her the part number and she confirmed they were in stock. This was about 430 in the afternoon just before closing. Trisha was kind and professional got the parts out the door that evening even though it was after the shipping cut off. Saved the day. I can tell you this entire company is represented by Trisha, anything they can do to help you out of a jamb they will absolutely go the extra mile and Trisha is the go to person. I am sure there are others there with her same attitude and professionalism. This is a great resource for all your fasteners needs.

Props to my saleslady (whose name I have sadly forgotten) for her can do attitude. Fast and efficient yet friendly and thorough. The items arrived nicely padded with brown paper. Im so happy youve stopped using those hard-to-dispose-of styrofoam peanuts. Fast to ship reasonable prices. Just excellent all around!

I sent in my online order then within a minute I realized I left off an item. I sent a message that requested an item be added to avoid a second shipping cost. I received a reply the next morning that the item I wanted had been added successfully and my order would be delivered as promised. Thanks to your staff for the flexibility and the help with my online order.
