Why this matters: the 12-point design provides multiple contact points for reliable engagement on metric fasteners, reducing the chance of rounding in tight spots. The extended reach of this deep socket lets you work with longer bolts or nuts that sit below a lip or behind a shield—no more awkward angles or incomplete fastenings.
Ideal for professionals and DIY enthusiasts who routinely service metric fasteners in cramped spaces. Add this DeWalt deep socket to your metric set for use on cars, motorcycles, power equipment, and shop projects where clearance is limited.
