I have used Military Fasteners for all my parts for a number of years and have never had a problem with my orders. Fast shipping, correct parts picking and lots of inventory. Thanks for your service.

My orders have been delivered on time or earlier all packaged well and in good shape. Thank you Military Fasteners.

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.

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.
