Tool Nut #9 x 3″ Combo Drive Black Oxide Cabinet / Furniture Screws, 100-Pack

Tool Nut’s black oxide cabinet and furniture assembly screws are designed to provide optimal fastening results in woods. The combo-drive recess accepts Phillips or Square Drive bits for versatility. Nibs under the screw head self-bore a clean countersink without pre-drilling. A smooth shank under the head creates a higher level of fastening strength. Sharp, aggressive threads and a Type 17 self-drilling point guarantee that you drive screws fast and accurately. This screw is not recommended for use in ACQ / pressure treated lumber or exterior applications.
