2Pcs Deep Thin Wall Impact Socket 21Mm Metric 6 Point Socket 1/2" Square Drive 5" Extra Long Phosphated CR-V Steel Industrial Grade Spindle Axle Nut Socket, Black

Made from Heat-treated 50BV30 chrome vanadium steel, the impact socket offers high strength, durability and wear resistance, ensuring long life and performance. Phosphate treated to enhance hardness, corrosion and wear resistance, providing extra durability and protection against rust. Its thin-wall construction allows access to fasteners in tight or hard-to-reach spaces where a standard socket may not fit, making it great for tasks that require a compact socket wrench. The thin-wall design also makes the wrench lightweight and easy to handle. The 6-point opening can fit the hexagonal fastener tightly and firmly, preventing slippage or loosening during operation, and can apply maximum torque. The radius corner design increases the contact surface to evenly distribute force to the flat surface of the fastener, preventing nuts and bolts from rounding off under high torque applications and extending tool life. 6-point impact socket can be used to install, remove and repair fastening bolts, shaft nuts, bolts on cars, machines, household appliances, engines, etc., suitable for automobile maintenance, mechanical equipment repair, construction, carpentry, home repair, etc.. Used with 1/2-inch electric wrenches, ratchet wrenches, L wrenches, bent rods, etc. Notice: Make sure to select the correct size to match the fastener to prevent slipping or damage. 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.
