These are handy hooks for 1/4" board. I still don't understand why almost all other hooks are designed for 1/8th hole board which is not standard and never was. The 1/8" hooks just fall out of the 1/4" board and are PITA. These hooks won't break even with heavy use and will hang on the hooks of my drill and the like. I've only used them up to about 15 pounds per hook (which is a lot) and they haven't given up yet. Good hooks and good price (pack of 50 pieces).
