Default Cowling fasteners?

Anybody used something beside the piano hinge on the cowling sides to keep the two pieces together? I was thinking of something like a zeus type fastener.

Default Cowling fasteners

Lots of discussion about this, use the search function. Dzus fasteners are probably not a good choice. Best choice seems to be with either Milspec or Skybolt

I never liked the look of Skybolts or other such fasteners and have always used hinge material - but this is builder preference so decide what you want.

I note however that the lower cowl hinge should be replaced with the more robust extruded hinge (MS20001) or aluminum plates with nutplates.

Skybolt’s are nice, but for the price and pain of installing them in a cowling with the engine already mounted and cowling painted, I would go back with a piano hinge in a heartbeat. The piano hinge is cleaner, lighter, cheaper.

Use something other than hinges across the top firewall and bottom by exhaust.

I started with the hinges, but then after many times spending several hours trying to get the last few inches in I said, quite literally, "screw it". Replaced the last nine inches with countersunk screws and tinnerman washers going into nutplates. Also used them for the bottom of the cowl.
