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.

Year in and year out - your staff is excellent, attentive, and spectacular. My last order I forgot an item, and called in to have it added. Sure enough there it is in the box, just as requested. Customer service is always fantastic. Keep up the good work!

I have been using Military Fasteners and have always had great service. Just this week I realized late in the day that we needed another part and I was able to add it to the order I had placed that morning. Being a small FBO on a shoestring budget that saved shipping cost and potential delays. Thanks Military Fasteners.

I was very pleased with the processing of my order from Military Fasteners. Placed my order very late on Thursday. Confirmation was immediate and received a tracking number the next day. It was delivered on the Monday. Excellent service from Military Fasteners
