SATA ST12109SC 3/8" Drive 6 Point Socket 3/4"

It pairs with a 3/8" drive ratchet and fits 3/4" hex fasteners. The 6-point design provides a secure engagement with hex bolts and nuts of that size range.

The socket is constructed from chrome vanadium steel for strength and durability, with a chrome-plated finish that resists rust and corrosion for long-lasting use.

Off-corner loading reduces rounding of fasteners by engaging the flats of the bolt at multiple angles, which improves grip and prolongs tool life in tough torque applications.

The size is clearly etched on the socket with large markings for quick visual identification, helping you grab the right tool faster on busy jobs.

Yes. The design is impact-ready and built to withstand high-torque automotive tasks when used with a compatible 3/8" drive ratchet.

It's well-suited for automotive repairs (engine bays, suspension work), equipment maintenance, and other tasks that require a 3/4" hex fastener accessed with a 3/8" drive ratchet in tight spaces.

Wipe the socket with a clean, dry cloth after use to remove grease or solvents. Store it in a toolbox or organizer to prevent impact damage and corrosion. Avoid prolonged exposure to harsh chemicals that could affect the finish.

Place the socket over the fastener, ensure full seating, then attach it to a 3/8" drive ratchet. Apply steady torque, making sure the socket remains fully engaged with the fastener to prevent rounding or slippage.

Use the correct size socket for the fastener, apply torque within the tool's and fastener's limits, keep hands clear of rotating parts, and inspect the socket for wear or cracks before use. If the fastener is damaged or overly tight, address it with proper techniques or a breaker bar to avoid tool breakage.
