We have been dealing with Military Fasteners and have always found them professional in their approach and happy to assist with any problems we may face in this ever changing industry. The parts ordered are those received, prices quoted are those we pay, the delivery times are acceptable considering we are on the other side of the world and should we require non listed stock we are advised where such stock may be procured. Thank you for your service over those years and we look forward to maintaining our relationship well into the future.
