3M Scotch-Weld TL90 Green Wicking Threadlocker

3M Scotch-Weld TL90 green threadlocker is a thin, wicking grade applied after assembly, so it can seep into the threads of fasteners that are already installed and lock them in place. It comes in 10 mL, 50 mL, and 250 mL bottles for maintenance crews and production lines. See Blue Threadlocker for medium-strength grades applied before the fastener goes in.
