Designed for 1/2" square drives, this Bosch PRO extra deep impact socket set includes three popular sizes from 17-21mm. It can handle hex screws, bolts and nuts in a variety of heavy-duty applications across a range of industries.
These impact sockets are particularly popular in garages and car repair due to the PET covers, which make it easier to change tyres without scratching the rims. They’re also well suited to other heavy industrial work – made from heat-treated CRMO steel, each socket is designed with a thick wall to resist high torque and features a black phosphate coating for protection against rust and corrosion.

• Three popular socket sizes – 17, 19 and 21mm
• Robust – for screwdriving tasks in heavy industrial work
• 86mm socket length – 1/2" shank for use with square drives
• Chrome-molybdenum steel – for resistance to high torque
• Phosphate coating – protects socket from rust and corrosion
• Easy identification – laser-marked and colour-coded sockets
• Plastic covers – change tyres without scratching the rims
