Installing Dzus Fasteners

A demonstration of installing the popular Dzus quarter-turn fastener. These are popular on homebuilt aircraft inspection doors, securing cowls and more. Simple and low cost compared to other fastener choices.

Well, I don't think explanations, demonstrations or educational videos in general get much better than that. And no annoying music in the background. That was perfect!

Well done! I have always remembered the Dzus fasteners from my AF time...they were used to secure system control boxes in the cockpit. Never knew how they worked, and looking at pics in catalogs didn't help. Now I know why there were always two "pop-rivets" next to each hole. Finally, a lifetime of nagging curiosity is satisfied!

Very helpful. I want to change the dzus fasteners on the cowling of my Cubby, so both are slotted. Whoever built it used ONE Phillips and One Slotted, which is just a nuisance checking the oil with the drain tool needing to switch from one to the other. Thanks N121WP

Exactly what I needed to know, and shown clearly. A-plus. I'm going to subscribe.

I wish all youtube videos were this helpful!

[@blondprince9507]

Good morning sir , really appreciate that , I think the distance between the two holes it's not the same . Best regards

[@kirkhopkins2735]

why pop rivet when there is lots of room to buck?? isn't there a collar to press fit the deus su it holds

[@jakebanning4735]

I take it another AME has stumble upon this video

[@anothersomebody8195]

Hollow pop rivets are cringe worthy

[@peterhealey2668]

Very detailed and informative, thank you.

[@ericdsrracer]

Thank you. Where did you purchase the sheet metal dimpler tool that works with your vice grips? I see Pegasus sells a dimpler for the actual Dzus fastener but not the rivet. Thanks in advance!

For 10 years, I have been looking for the name of this fastener. I have a T368 transmitter.

[@stevenstyles7602]

Can you get stainless steel ones? Mine are rusty

[@shawnrussell375]

How do you determine how far apart to put them?

[@borden2417]

I like your video on Dzus fasteners, but --all I can find is springs with 3/32 inch holes. Were do you get the springs with 1/8th inch mounting holes. Help, my airplane project needs these.

[@jimmyduncan7650]

Thanks for the video, quite helpful. Can you suggest a reliable supplier please?

Hi, Thanks for posting. What about those retainers that normally get used instead of the snap ring ? Those retainers that appear at first like a canvas grommet and they get squeezed with a special tool or sockets? Regards from Alaska.

[@marklangmann2163]

BetterAircraftFabric You are best off not to use a snap ring as they are hard and wear a large hole in the stud hole in no time. For the common 5/16 diameter as demonstrated in video use the proper GA5 grommets, they are soft and formed with a bar with a 5/16” hole and a C clamp.

[@ak47suki242]

Great video.

[@mohammedpilot2335]

Thanks

[@LL-cz5ql]

good stuff

[@townsendliving9750]

Anyone else start looking for their cat while watching this

[@pbmanf1]

Not the way to do it. Make or by the dzus jig as this is way to slow. And you cant dimple fiberglass flush use flush mount rivits. See Tim McAmiss racing video

[@ronjohnson9507]

You countersink fiberglass

[@ctsteve1967]

that was not at good way to show how to install

[@jamescole3152]

One of those inventions that just didn't make it..
