This assortment is made in China.
Spacers for BEHIND the board. Screw through a peg hole (upper right, for example), then through the spacer, then into the wall. Peg hooks need space between the board and the wall to work properly.
It is for 1/8 with plastic clips to hold the hooks in place.
Better peg locks can be purchased separate at www.pegitz.com Those are not straps...they are adapters that fit into the hold of the pegboard and hold the hook. They are cheap, easy to use and they work!
For securing the hooks, place it above the hook with end going to pegboard holes. It prevents the hooks from moving.
20 actual hooks, 6 screws and 6 washers comprise of the "32 pieces". 16 additional locking hooks are provided for free as other feedback articulates that they don't stay in without them.
These are hooks etc to be used ON the pegboard, not to mount the pegboard itself.
