SATA GL12411 3/8" Drive 6 Point Deep Socket 18mm

A 6-point design engages the hex corners of fasteners more contact area, which helps prevent rounding and distributes torque more evenly for longer socket life.

Off-corner loading aligns the socket with the fastener corners more accurately, reducing rounding and wear on both the fastener and socket during high-torque use.

Size: 18mm; Drive: 3/8"; Type: deep socket and 6-point; Material: chrome vanadium steel with a corrosion-resistant chrome-plated finish; Depth: deep socket design; Markings: clearly engraved size for quick identification; Grip: knurled edge for non-slip handling.

A deep socket has extended length to reach fasteners that sit deeper or recessed, such as long bolts or fasteners in tight spaces. Use it when standard sockets cannot reach the fastener head.

Attach the socket to a compatible 3/8" drive ratchet, align with the fastener, and apply steady torque. The deep profile and six-point design help maintain engagement and reduce slippage during use.

This socket is specifically sized for 18mm hex fasteners. Use with fasteners that match the 18mm hex dimension for optimal engagement.

Wipe clean after use, keep it dry to prevent rust, and store in a dry toolbox or organizer. The chrome-plated finish provides corrosion resistance, but regular cleaning helps extend life in oily or dirty environments.

Yes. It’s designed to withstand high torque typical of 3/8" drive sockets and is built from chrome vanadium steel with a robust finish to handle demanding use.

Use it for automotive maintenance (engine and suspension bolts), machinery assembly, or any task needing access to recessed or hard-to-reach fasteners that are 18mm hex in size.
