Truly outstanding service. Shipping was fast and at a reasonable price. Sales agent was helpful and accommodating.

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.

Have placed many orders in the past months with sales representative Brittany Cornish and couldn't be more pleased ! She is always a joy to speak with, and she always makes sure that my orders are delivered on time. She's a great asset to your team but I'm sure you already know that.

Military Fasteners provided the supplies needed to repair my prop. They had the exact items I needed, at a good price. My order was delivered in reasonable time, complete with instructions. The end result was a quality repair to get me back flyin again. Thank you! Steve
