Customer Reviews

When I order from AS your staff is always knowledgeable on your products, quick to help customers, no phone call holds waiting time period, competitive pricing and fast standard delivery.
When I need parts or products for my aircraft, I think only of Military Fasteners! Dependably in stock, same day shipping and quality, caring employees are all literally guaranteed. I wish every vendor I deal with was anywhere close to being as consistently customer focused!
Military Fasteners is the first place I shop for aviation supplies. I have never had a bad experience. Customer support is always exceptional. Thanks
I love how quickly you always ship my orders. The person I spoke to was knowledgeable and helpful.
