Customer Reviews

Professional & timely in responses & delivery.
I have been dealing with you folks for years as a corporation customer and personally. You are the industry standard on quality of product and service.
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.
Service is excellent. I appreciate your company willing to fill small orders. Long term projects call for small orders from time to time and your willingness to help the home builderis exceptional. Thank you for great service.
