Disassembled – Do Not Remove Enter the name of the object being torn down
and a picture of the completely disassembled
product.
• The TackSert® pins can
replace a threaded hole and
screw, thus eliminating the
need for loose hardware, while
providing a permanent
solution. It can be installed
with a simple pressing action
instead of a more complicated
turning action.
• The TackSert also eliminates
the need for a pressed in
insert.
