Customer Reviews

Received exactly as ordered, exactly when promised. Superb customer service as always.
Ive been buying aircraft parts and supplies from Military Fasteners for 3 years as Ive built four different homebuilt aircraft. I have ALWAYS been perfectly satisfied with all facets of the process. Parts are almost always shipped the same day as I order them, even if I order in the afternoon. Im usually always able to find what i need on the website, and if not, I can call and be helped by someone who knows what he or she is doing. Your people make me feel like they really care about me. Prices are fair. I wish I could run my company as well as you run yours!

I recently had the pleasure of working with Military Fasteners and I couldn't be more satisfied with the experience. Trisha Hawkins provided exceptional customer service and went above and beyond to ensure I found exactly what I needed. The quality of the fasteners is top-notch and the delivery was prompt. I highly recommend Military Fasteners for their outstanding products and excellent service. Thank you, Trisha, for making the process so smooth and efficient!
