Grip-Rite 3GCS5 #9 x 3 in. Star Drive Dual Flat Head Coarse Thread Construction Screws feature a T17 point which means you won't need to pre-drill during construction. Designed for interior, wood to wood applications, the coarse auger threads reduce splitting and speed installation. The T-25 star drive reduces slippage and handles more torque than other designs. Yellow zinc coating combats corrosion and adds an attractive color to wooden construction applications.
