Customer Reviews

None--Keep up the good work. Always 100% satisfied.
Staff very supportive and informative. Order was shipped extremely promptly and correctly. GREAT customer service!
With ordering parts, I was assisted by Trisha. Extremely helpful, courteous, and professional. When receiving the items, there was a small discrepancy. I contacted Trisha to let her know, and not only did she and another professional, Paige, work with me right there to rectify the situation. They made sure I received new items in a timely manner, at no extra cost. Taking accountability and being serious in keeping with their high standard product has my respect and future business.
I have been doing business with Military Fasteners for a number of years. Every Time I have needed a question answered in finding something for my projects Military Fasteners has always been there. The people I talk to are helpful and knowledgeable concerning all the vintage planes I have called looking for a special item needed. Thank you for being YOU!
