Ordered the plugs on Tuesday and received them Friday morning. Great service. Items arrived as ordered. You run a tight ship.

Service was great, shipped and received with paperwork as promised, definitely would give a two thumbs up.

I have built an airplane with parts from Military Fasteners. In the last years I have only had one issue involving warranty problems and that was resolved by the factory. Good service and quality parts/availability are very good at Military Fasteners.
