Driver # 1 Square
Item Number: 250R1
In 1906 Lymburner Robertson developed the socket head screw, also known as the square recess screw. This new screw was self centering and drove with four points rather than two allowing more torque to be applied. The screw was widely adopted by cabinet makers and furniture makers who needed a screw that could be driven more reliably into hard woods. Same as X950-1
