SKU 99911 Driver
The Grisham One-way steel safety screw driver tool is designed to drive large 1 way tamper proof screws that are generally used on security door and window bar installations. The Drivers hood encapsulates the safety screw head and helps prevent slippage during the fastening process. The driver will accept pan-head safety screws up to 3/4 in. in diameter. The 1/4 in. driver tool shank will attach to any conventional drill chuck or impactor.
