I love your website. Can hardly believe how fast & accurate the orders come. Am building a kit plane, need a lot of small hardware and electrical the past few months. There has not been a mistake in the last dozen orders.

At every point, Dania McLean's help was crucial and showed a great dedication to the business. She handled my questions with amazing skill right away, making sure every one of them received a comprehensive and perceptive answer. Her unwavering professionalism and contagious optimism, which made every interaction enjoyable, were what really stood out.

I can always count on Military Fasteners to give me the best selection of aircraft parts and supplies. Also always get fast shipping, and appreciate the USPS option that is much less expensive than the overnight shippers for us located in Southern California. Thank you for making it easier to keep our general aviation and experimental aircraft flying!

I placed this order late at 4:15 over the phone, 15 minutes past the cut off time.(Which rarely happens) It was critical for us to get the sparkplugs as a customer had called me and scheduled to bring his plane in the next day to have all his plugs replaced. My sales agent said she would personally go and pull the product so it would ship that day, and she did what she said. She saved me the embarrassment of telling my customer I forgot to order his parts on time and making him reschedule a maintenance visit. I am thankful you have people like her who really care about the customer and want to put in the extra effort for customer service. In my aircraft maintenance business I purchase everything I can first from Military Fasteners before I go looking for other venders. I use Military Fasteners because of the great customer service, free shipping (which is one day ground), large selection on hardware and materials, and competitive prices. I am a loyal customer and I order 2-3+ times a week. Thank you for the great service that your people provide at Military Fasteners.
