My experience in doing business with Military Fasteners through Trisha Hawkins is nothing short of GREAT! She is knowledgeable, attentive to detail and very helpful. This makes my purchase a lot easier and faster lead time. She is an asset to Military Fasteners.

Best source for mil spec hardware. Website is user friendly, inventory is expansive, overnight shipment is a huge plus, and customer support is responsive and very helpful.

5.0

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.
