Carmen M.

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.
