Fast, efficient, knowledgable, good all round people and I will be doing more business with them. I have an older plane and it is needing some refinements. Thanks for your service!

I recently had the pleasure of working with Military Fasteners and I couldn't be more satisfied with the experience. Trisha Hawkins provided exceptional customer service and went above and beyond to ensure I found exactly what I needed. The quality of the fasteners is top-notch and the delivery was prompt. I highly recommend Military Fasteners for their outstanding products and excellent service. Thank you, Trisha, for making the process so smooth and efficient!

I can say that Military Fasteners was able to deliver the part to me very quickly. I live in a very remote area in the Tennessee mountains and typically have to wait up to two weeks to receive deliveries. Sometimes, the delivery guys cannot find my house at all, and they have to leave my packages at the local general store. But with Military Fasteners, my packages always find my front door step and in great condition. This package arrived nearly a week earlier than expected, and that was over the New Years holiday! Great work, Military Fasteners, on your delivery service. Thanks!
