The Bosch PRO 9 Piece 1/4" Drive Deep Hexagon Impact Socket Set is a professional-grade socket set designed for tackling hex screws, bolts, and nuts with a square-drive impact wrench. Manufactured from heat-treated CRMO (chrome-molybdenum) steel with thick-walled construction, these sockets are built to withstand high torque and heat — making them well suited to demanding applications such as plant installations and heavy industrial work. Each socket features a black phosphate coating for reliable protection against rust and corrosion. Laser-marked and colour-coded sizing makes it straightforward to identify the correct socket at a glance on site. A groove and through hole allow the sockets to be secured to your impact wrench using a pin and ring for a particularly firm hold when conditions demand it.
