Thread an 8-32 flanged nut on the screw. While using a flat
blade screwdriver to hold the screw, thread the control horn
on the screw.

: Always use threadlock on metal-to-metal
fasteners to prevent them from vibrating loose.

the nut against the elevator to secure the screw. We
recommend using 30-minute epoxy on the screw as
