What's it called when mechanics do this ?
I was once looking into building a kayak kit that would have required lots of wire to hold plywood parts in place until fiberglass went over them.
I tried finding safety wire pliers then as I knew they existed from my brother-in-law who had been an A&P mechanic.

Yes, for aviation-spec fasteners.

Safety wire isn't just for holding things it is for keeping things that do come loose from going into engines, intakes, getting into turning mechanisms or your face, last thing you want is a bolt being sucked down an intake tract of a single engine plane at 10,000 ft...

When I was in the Navy the radio's and a lot of other electronic equipment in airplanes was mounted in racks with wing nuts that were safety wired in place. I remember we used specific gauges of wire and the number of turns/twists per inch was specified.

If you saw the documentary about attempting to recover a WW II era 4 engine bomber off the ice in Greenland I think, you will understand why safely securing everything in an airplane is important.

Bolt sucked down an intake better than being on fire?

Stitch and glue! Chesapeake Light Craft or Pygmy Boats? I did use my safety wire pliers for the CLC 17 I built.

For anything aviation-related, Aircraft Spruce is always a good place to look.

Trapper—Pygmy Boat. But I never went ahead with it. My son is now married, has a year-old boy, lives 3000 miles away.
Here in CA two granddaughters—no time for anything like building a kayak. And no space. Might get an inflatable with drop-stitched walls, floor. Hear they paddle pretty well.

Had to do it by hand in school, didn't get to use pliers till I got to the shop.
Pretty sure it was 10 per inch.
Working with hydraulics and such in jets everything was safety wired or had a cotter pin.
Small cotter pins tore me up worse than safety wire.
