Military Fasteners provided the supplies needed to repair my prop. They had the exact items I needed, at a good price. My order was delivered in reasonable time, complete with instructions. The end result was a quality repair to get me back flyin again. Thank you! Steve

Any time I need anything it is here when I need it without question. I have tried other suppliers and ship dates are not honored sometimes it can take two weeks for item in their stock!! Thanks for being consistent and prompt.

We worked with Ramona at Military Fasteners for a few items that we needed right away to complete a job. Ramona processed our order quickly and efficiently and made the experience stress free when it could have been quite challenging. The items came with all the correct documentation too which was also very important to us.

Alternator was in stock, shipped same day, arrived quickly (even though I chose standard shipping during the height of the Christmas rush), packed well and at a good price. Well done, Military Fasteners, well done!
