Customer Reviews

My order was a small order of hardware. The order arrived well packaged, in a timely manner via US mail. I continue to receive excellent service from Military Fasteners. Thank You!
Had an order discrepancy. Kristen Belmont to the rescue! Very well taken care of. Thanks to Military Fasteners for having a wonderful C.A.R.E team!
Ordering is simple and my parts are always shipped promptly and arrive well packaged. Military Fasteners is always my go-to store when I need something for my homebuilt project.
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.
