I've been a Customer since the early 90s. Never an Issue with products or Customer Service. I recently purchased a New Concord Battery, Harness and Battery Minder Charger. I clicked the wrong button and did not order the correct charger for the Concord. Called Military Fasteners when it was delivered, told the gal what I did and she said well get the right one on the way and e-mail you the Return Authorization. I sent the wrong one back and two days later the correct one arrived. A few days after that my Credit Card was reimbursed the full amount for my incorrect order. By any Business Standard, who could complain about that kind of Service!!! Keep up the Great Work...


Never had any problem since I began ordering from Military Fasteners for some time now! Always got what I ordered :)


Always a pleasure to call in an order and talk to the staff. They are helpful and prompt in getting the order out


Several recent orders. All excellent service. All quality parts as expected.
