SATA SC34213 3/8" Drive 6 Point Impact Socket 18mm

The 6-point configuration grips the flat sides of fasteners, which reduces rounding and slippage. This helps you apply torque more reliably and extends both the socket and fastener life in demanding applications.

The socket is made from chrome molybdenum steel for exceptional strength and durability, and it features a black phosphate finish that resists rust and corrosion. This combination is designed for long-lasting performance under heavy use.

Yes. It is specifically designed for 3/8" drive impact tools and is sized for 18mm fasteners, making it suitable for impact-heavy tasks where high torque is required.

The socket features large, easy-to-read markings that clearly indicate the size, helping you spot the 18mm size at a glance during work.

It's ideal for automotive repairs, maintenance tasks, and mechanical work where high torque and a secure fit are needed, such as suspension work, driveline bolts, and engine accessory fasteners.

Ensure the socket completely engages the fastener, use it with a compatible 3/8" drive impact tool, avoid using it with misaligned extensions, and apply steady torque. The off-corner loading helps reduce rounding, but always match the size to the fastener to minimize slippage and wear.

If you’re choosing between sizes, consider whether your fasteners are 17mm, 18mm, or 19mm.

Keep it clean after use to remove debris, wipe away moisture to minimize corrosion, and store it in a dry kit. The black phosphate finish provides corrosion resistance, but avoiding prolonged exposure to moisture will help preserve its finish and performance.

Yes. The Chromium-Molybdenum steel construction, 6-point design, off-corner loading, and clear size markings all contribute to durability, reliability, and efficiency in tough tasks. It’s a solid choice for professionals and enthusiasts building a versatile impact socket set.
