Brusso Precision Small Box Hinges feature rectangular knuckles which stop the lid in a vertical position so it won't drop back. Hinge pins are precision ground tool steel, with pin boxes that are first drilled, then reamed, for smooth fit and operation. Use in boxes of all types and small doors where the opening angle won't exceed 100 degrees. This hinge fits a minimum stock thickness of 7/16". Small hinge (Woodcraft #145286) fits a minimum of 5/16". Leaf thickness of both is 3/32". Sold in pairs; screws included.
Pre-drilling is recomended: For #4 screws use a 5/64" straight pilot drill for hardwoods and a 1/16" for soft woods. Use a 7/64" for hardwoods and 3/32" for softwoods if you are using a tapered pilot drill.
