Customer Reviews

I placed an order with Lindsey at Military Fasteners late afternoon, 3:15 to be exact and she was nice enough to expedite my order and made sure to get it shipped that day. Great company with great people.
All of my orders have originated thru your online system and have arrived on time as advertised. Your system performs great. I can decide while ordering how I want it shipped and what cost. All things said, I find your system very easy to order thru.
Easy catalogue to find things. Battery fit perfect. Legal again for another two years. Delivered sooner than promised!
Excellent service all round. The parcel arrived on my doorstep, in a regional Australian town, on the morning of the fifth day after placing my order.
