Military Fasteners is my 'go to' aircraft supply company. Every purchase has been a pleasure. Great products and shipping is good. Shipping cost is always a concern but I know you have little to due with that. Thank you Military Fasteners.


I count heavily on Military Fasteners for helping me maintain my aircraft with the right parts and fluids.


Amelia does a great job for Highpoint.


Professional and friendly sales rep! Quick quoting, ordering, and shipping. Will order from mil-fasteners again.
