1/2" Outside Diameter, Large Round Washer Head provides for better adjustment control.
When building a typical 5 piece drawer box, it is desirable to have the ability to move and precisely adjust the drawer front in order to align all of the drawer faces.
An oversize hole (5/16" - 3/8") is drilled through the drawer box
The drawer front is then attached using two Drawer Front Adjusting Screws.
During installation, the Drawer Front Adjusting Screws can be loosened slightly to allow for drawer front adjustment and alignment. The screws are then re-tightened
A hardware screw or "set-screw" can be used to secure the drawer front into place.
