Customer Reviews

You guys shipped right away and it was delivered on time. Thanks for the prompt service.
I routinely use Military Fasteners and have them on our Approved Vendor List. They already understand traceability requirements and their website always seems up to date and accurate. Same day shipping is a big deal for us as well."
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!
