Customer Reviews

The ordering process was very smooth and your site is user friendly and my part was delivered promptly.
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.
Great to deal with. Quick responses are so important to businesses and they definitely do that....
Trisha Hawkins was extremely helpful and professional. Got my order quoted and processed in under 5 mins.
