3/8" Drive Deep Impact Socket Set - 16pcs Metric (7-22mm)/15pcs SAE (1/4"-1"), 3"&6" Extension Bars, 6-Point Design, Cr-V Steel, Heavy-Duty Storage Case

Dedicated Deep Sockets for Recessed Fasteners：100% deep socket design reaches hidden or recessed bolts/nuts (common in auto engines or machinery) that shallow sockets can’t access, solving the pain point of tight-space operation. Full Metric/SAE Coverage + 6-Point Grip：Includes 16pcs Metric (7-22mm) and 15pcs SAE (1/4"-1") sizes to fit global fastener standards. 6-point socket design grips fastener flats tightly, preventing slipping and stripping—safer for high-torque impact use. Heavy-Duty Build + Organized Storage：Made of Cr-V steel for high torque resistance and durability, withstanding frequent impact wrench use. Comes with a heavy-duty storage case that sorts sockets by size, plus 3"/6" extension bars, ensuring easy carry and no accessory loss.
