This is just a note to say how much I appreciate Military Fasteners. Your prices are fair, your shipping is fast and the costs are reasonable. The paper and online catalogs have a huge assortment of products. I also like the fact that there is no minimum order.

Brittany was attentive to our needs. We had to source some other products you didn't have elsewhere. We would have preferred to place an order a one place. Will come back and order another time.

I ordered 2 custom coax cable assemblies in the early afternoon, and was shocked when I was notified they shipped later that day! Great service!

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.
