3Pcs 6 Point Deep Impact Socket 1/2" Drive 21Mm Metric Socket 3" Long CR-V

Made from quality chrome vanadium steel, which has ultra-high strength and impact resistance. It is not easily deformed or cracked under sustained high-intensity impact, effectively providing solid assurance for the durability and high performance of the socket. The surface is processed by hot cutting technology, ensuring flat and smooth sleeve ports without burrs or flashes, thus preventing scratches on bolts and workpieces during use. Further strengthened by black phosphating treatment, it enhances surface hardness, corrosion resistance and lubricity, reduces friction resistance with bolts, enables smoother torque transmission, and effectively extends the service life of the tool. The impact socket has a 6-point opening, which can closely fit the hex shape of fastener head and apply maximum torque without slipping easily. The radius corner design can 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 drive electric wrenches, ratchet wrenches, L wrenches, bent rods, etc. Notice: Apply even pressure and grip the socket firmly on the fastener to avoid stripping or rounding off the corners. Align the socket properly with the fastener at the correct angle to ensure a secure fit and prevent slippage during operation.
