I just started an Ultra Light project and have been very happy with the orders I've placed with ACS.

Great supplier, great products, great prices. Trisha Hawkins hooked us up with the bolts we needed in a very efficient and friendly manner.

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.

4.0

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!
