I worked with Isaac Beltran and he did a great job and rare to find.....someone with attention to detail.

Props to my saleslady (whose name I have sadly forgotten) for her can do attitude. Fast and efficient yet friendly and thorough. The items arrived nicely padded with brown paper. Im so happy youve stopped using those hard-to-dispose-of styrofoam peanuts. Fast to ship reasonable prices. Just excellent all around!

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.
