As normal with Military Fasteners for many years, no issues. I order the parts needed and they send them. Just fair prices and good service.

Trisha Hawkins and her team at Military Fasteners are absolutely incredible. We do a lot of Government and Military work and due to this there are a ton of restrictions with what products we can use. I called Military Fasteners (MF) with an extremely HOT request. Trisha was able to source those part numbers, tell me they were in stock and ready to ship. I ordered these on a Wednesday at 4:00pm. They shipped the same exact Wednesday, we received that weeks Friday, even though we were guaranteed Monday/Tuesday. Trisha - THANK YOU! Trisha's Team - THANK YOU! I will only be ordering my military hardware from you all.
