Customer Reviews

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.
Always very helpful Employees. Stock seems to be getting better as well. No problems ever.
It is very good service. I appreciate Brittany Cornish provide us the parts we ordered.
To say I am satisfied with all purchases from Military Fasteners is a bit of an understatement. Selection, price, packaging, shipping exceeds expectations. You are my number one choice for my aircraft needs, thank you, Charles
