Excellent service all round. The parcel arrived on my doorstep, in a regional Australian town, on the morning of the fifth day after placing my order.

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!
