Phillips head screwdriver holder - SS system

One of many wall hanging tool holders. This one is designed to hold my Phillips head screwdrivers. The hole sizes are (from left to right) 7.0, 6.0, 4.2, 7.0, 4.2 and 3.5 mm diameter.All wall hanging tool holders come with countersunk holes for screws to attach to a wall and are designed to interlock with other holders in my collection (always adding new ones).
