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.

Everything exactly as ordered! Quick and reasonable cost of shipping. Thanks for the XLNT service.
