I have always turned to Military Fasteners for all my aviation needs. They have never let me down and are totally trustworthy, fast and efficient. They have great choices from reasonably priced, to the best available. I've never seen the need to look anywhere else..Why would I..

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.
