, and swing back.

is a hex head cap screw,

Install a replacement shear bolt on the vertical faces on
the side opposite from the pivot bolt. Do not use a higher
grade bolt, or marker hang-ups may result in machine
damage. Do not use a smaller or lower grade bolt, or
you may experience nuisance shears.
