2Pcs 6 Point Deep Impact Socket 8" Long 1/2" Drive 21Mm Metric Socket

Made from quality chromium molybdenum steel, the impact socket combines high hardness and excellent toughness. 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 treated with secondary heat treatment and carbon phosphating composite treatment, which not only deeply strengthens the hardness and structural stability of the sleeve substrate, but also forms a dense protective film on the surface, effectively prevents moisture infiltration, significantly improves rust and corrosion resistance, and extends the service life of the product in harsh environments. 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 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. The integrated anti-drop rubber ring locking pin, rubber ring and metal locking pin can be inserted into the pin hole on the drive end to connect tightly with the wrench, ensuring a secure connection that will not wobble or fall off. 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.
