The Bosch PRO 9 Piece 3/8" Drive Hexagon Impact Socket Set is a professional-grade socket set designed for driving hex screws, bolts, and nuts using a square-drive impact wrench or ratchet. Manufactured from heat-treated CRMO (chrome-molybdenum) steel with thick-walled construction, these sockets are built to withstand high torque demands without deforming or failing. A black phosphate coating provides reliable protection against rust and corrosion, making the set well suited to demanding environments such as plant installations and heavy industrial work. Each socket is laser-marked and colour-coded for quick, at-a-glance identification, reducing time spent searching for the right size on site. A groove and through hole allow the sockets to be secured to your impact wrench using a pin and ring system, providing a positive hold when extra security is needed.
