Milwaukee 3/8″ Drive 20mm Deep Socket

ANTI-ROLL PRECISION FASTENING

For the shop foreman and the fleet maintenance pro, Milwaukee has re-engineered the standard socket into a high-utility asset that solves the perennial headache of rolling tools and rounded-off fasteners. This 3/8″ Drive 20MM Metric Deep Well Socket is built with a mechanical geometry that prioritizes job site stability and maximum torque transfer, ensuring your hand tool investment lasts through years of heavy-duty cycles.

• / FOUR FLAT SIDES: Innovative square-profile architecture prevents the socket from rolling across sloped surfaces and allows for secondary wrench-assist when extra leverage is required.
• / DEEP WELL ARCHITECTURE: Extended profile provides essential clearance for threading over long bolts and reaching into recessed mechanical assemblies.
• / STAMPED VISIBILITY: High-contrast metric sizing is stamped directly into the flat faces for rapid identification in low-light environments.
• / ANTI-ROUNDING GEOMETRY: 6-point design features optimized interior corners to engage the flats of the fastener rather than the points, preventing stripping.
• / LIFETIME GUARANTEE: Professional-grade chrome construction backed by Milwaukees commitment to long-term reliability.
