The DUKE Tools Perth® 20 Piece 1/2 Inch Heavy Duty Deep Impact Socket Set is precision-forged from heat-treated chromium-vanadium (Cr-V) steel alloy, delivering a tensile strength exceeding 1,200 MPa to handle repeated impacts without deformation or fracture. The 6-point hexagonal internal geometry maximises contact surface area by up to 30% compared to 12-point designs, minimising fastener rounding and enabling torque transmission up to 1,000 Nm when paired with compatible 1/2-inch impact wrenches.Each socket extends to a uniform 78mm depth, accommodating recessed or extended-thread fasteners common in Australian vehicle fleets, such as those in Toyota LandCruisers or heavy-duty Isuzu trucks prevalent in mining operations. A black phosphate coating provides superior corrosion resistance while the off-corner drive design reduces stress concentrations by 20-25%, enhancing safety during high-vibration tasks.This set is ideal for professional mechanics working on 4WD suspensions, structural engineers tightening M12–M24 bolts on construction sites, and industrial maintenance teams in manufacturing plants — all backed by a 12-month warranty.
