Military Fasteners always delivered on what I purchased. And what I returned Military Fasteners is prompt on returning it as crediting my account. I only order for myself, so I'm quite satisfied the way Military Fasteners takes care of me only as a occasional customer. Thank you Military Fasteners Personnel.

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!
