SATA GL34314 1/2" Drive 6 Point Impact Socket 21mm

A 6-point (hex) design increases contact with the fastener head, improving grip and reducing rounding during high-torque turning.

1/2\" drive, 21mm size, off-corner loading design, heavy-duty impact rating, durable construction, and clearly marked size for quick identification.

Yes. It’s made for use with 1/2\" drive impact wrenches/drivers and will fit standard 1/2\" drive tool systems.

Off-corner loading reduces rounding and spread of load, which helps protect fasteners and prolong tool life when you’re applying high torque.

Attach it to a compatible 1/2\" drive hammer or impact wrench, ensure the fastener matches the 21mm size, apply steady torque in the intended direction, and avoid hammering the socket onto a fastener.

Ideal for automotive repairs, heavy equipment maintenance, and any high-torque tasks involving 21mm fasteners where a 1/2\" drive is used.

The socket is built from premium materials designed to withstand heavy use and impact loads, providing long service life in demanding environments.
