Grip-Rite 134GCS1 #8 x 1-3/4 in. star drive bugle head 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.
