BIG TIMBER® 316 Stainless T-25 Flat Head Wood Screw, 69-Count Bucket, 1STX103, #10 x 3 IN

The STX screw is 316 marine grade stainless steel for superior interior/exterior corrosion resistance. The star drive handles 2X the torque as Phillips or Square Drive while extending the life of the bit. Under-head cutting nibs aids in self countersinking. It has an aggressive knurl that enlarges the hole to reduce splitting and drag to help draw lumber together. This product is backed by certified independent testing (TER 1911-02).
