Customer Reviews

I am a retired AME/Pilot. I have been restoring a 1946 Globe Swift and have relied on the support and expertise provided by your sales staff. My experience has been very positive. In return, I buy everything I can from Military Fasteners. You are my preferred supplier. Thank you.
Great American company! Go Military Fasteners!
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 can always count on Military Fasteners to give me the best selection of aircraft parts and supplies. Also always get fast shipping, and appreciate the USPS option that is much less expensive than the overnight shippers for us located in Southern California. Thank you for making it easier to keep our general aviation and experimental aircraft flying!
