When you’re dealing with tough fasteners, the DeWalt 18 mm Metric 1/2 in. Drive Deep Impact Socket is built to rise to the challenge. Crafted for impact use, this 6-point deep socket pairs a rugged forged-steel body with a durable black oxide finish to deliver reliable, long-lasting performance on metric hardware.
Built for impact performance
The socket is impact rated and ready for high-torque sessions with 1/2" drive tools. Its 6-point geometry provides maximum contact with the flats of hex fasteners, improving torque transfer and reducing the risk of rounding under heavy loads. The deep design offers extended reach to fasteners located in recessed spots or behind components, making it a practical choice for cramped workshops and automotive bays alike.
