3Pcs 6-Point Deep Impact Socket 19Mm Metric Socket 1/2" Drive 11.5" Long

Our impact sleeves are made of 45# steel and undergo secondary heat treatment, giving them high hardness, high strength, toughness, and excellent oxidation resistance, enabling them to withstand the high torque generated by high-pressure impact tools. The surface is phosphated, providing excellent corrosion resistance, wear resistance, and rust prevention, ensuring they are not easily worn in high-friction environments. Each socket features a pinhole base design, allowing for the insertion of a locking pin (NOT inluded) before use to enhance tightening force and provide additional stability and safety during use. The radiused 6-point opening design enables a tight and secure installation of hexagonal fasteners, allowing maximum torque to be applied while distributing force evenly across the fastener's surface, preventing the rounding of nuts and bolts under high torque. The hex deep impact Socket can be used to install, remove and repair fastening bolts, axle nuts and bolts on cars, machines, home appliances, engines, etc. It is suitable for car repair, mechanical equipment repair, construction, carpentry, home repair, etc. It can be used with 1/2-inch square drive electric wrenches, ratchet wrenches, L-type wrenches, bending rods, etc. Apply even pressure and grip the wrench firmly on the fastener to avoid stripping or rounding off the corners. Align the wrench properly with the fastener at the correct angle to ensure a secure fit and prevent slippage during operation.
