I attach a magnet to the top of all of my ladders to hold nuts, bolts, nails, screws and other metal fasteners while I work. It’s like having an extra hand!
It’s best to use a round base magnet or one that is made with a hole in the center for easy attachment to your ladder. Then all you need to do is drill a hole and use a bolt and nut to hold the magnet securely in place. These magnets are also strong enough to hold small metal tools such as a handheld screwdriver. — Mark Ammons
