Great product at a good price, fast delivery. Easy install, fired up perfectly right out of the box.

4.0

I would like to thank Military Fasteners for their accurate speedy delivery of hardware. Many people don’t realize that when an aircraft is grounded that schedules cannot be met. Their attention to being timely for a $36 dollar purchase made an airplane ready within two days.
