10-9X1 3/4 Square Phillips Drive Round Washer Deep Thread Type17 2/3 Thread Black Oxide (Pack Qty 2,300) BC-1028DXRW17B

The deeper thread design offers greater resistance to pull-out forces. The chip cavity (or auger point) enables the fastener to drive—especially in denser woods—without pre-drilling a pilot hole. The head offers a greater bearing surface than a countersunk design. Used to attach surface-mounted door hinges or lock hasps into dense woods or when attaching two pieces of wood through a pocket hole.
