3/8 Drive Deep Impact Socket Metric 8-19 mm

Replacing a full socket set because one size broke or disappeared is an unnecessary expense. This Teng Tools 19 mm individual socket lets you fill the gap in your existing kit or start building a custom metric impact collection piece by piece, purchasing only the sizes your work actually demands.

The deep well profile reaches past surrounding structure to engage nuts and bolts that sit on long studs or inside recessed cavities. Large metric fasteners on suspension arms, drivetrain housings, and heavy-equipment mounts frequently require this extra reach, and the deep design delivers it without forcing you to add extensions that increase flex and reduce torque accuracy in your drive stack.

Built to absorb the repeated shock loading of pneumatic and battery-powered impact drivers, this socket handles the punishing duty cycles professionals face every day. The 3/8 inch square drive fits the mid-range impact guns, ratchets, and breaker bars most mechanics already own, providing a strong yet compact connection for moderate to heavy torque applications across automotive, agricultural, and industrial work.

The 19 mm metric across-flats dimension seats precisely on the matching fastener, ensuring full-contact engagement that prevents corner rounding under impact loads. Choosing the correct metric socket rather than an approximate imperial substitute protects both the hardware and the tool, extending service life and reducing costly rework caused by damaged fastener heads.

Whether you are pulling axle nuts on a service truck, swapping manifold studs on a diesel, or maintaining hydraulic fittings on a skid-steer, this individual deep well socket gives you the exact size and the impact-rated performance the job requires.
