Paige is the best :)


I am unable to add any suggestions. Military Fasteners is an on time provider. I have never understood why the orders from you company are shipped and arrive in time given to me. Other companies say same day ship or the following day and it takes much much longer for the product to arrive. All I say, Good Job


Easy catalogue to find things. Battery fit perfect. Legal again for another two years. Delivered sooner than promised!


Your team is first class, I always order from Military Fasteners because I know my stuff will come ASAP. Keep up the great work.
