Gearwrench 80406 Deep Hand Socket 3/8 Drive 20 Mm 6-point

Product Description

The GEARWRENCH 80406 is a 20 mm, 6-point deep hand socket with a 3/8 inch drive, built for mechanics, millwrights, and general trades who need extra reach on fasteners recessed below a surface or sitting on a long stud. The socket is machined from alloy steel with a chrome-plated finish that resists corrosion and wipes clean easily. At 2.5 inches in overall length, it provides the depth needed to clear bolt shanks, studs, and recessed hardware that a standard-length socket cannot fully seat on. The 6-point geometry concentrates drive force on the flat faces of the fastener, reducing rounding on worn or tight hardware.

This socket is suited for automotive repair, equipment maintenance, and light industrial work where metric fasteners are common. The 3/8 inch drive is a widely used size in mid-range torque applications, compatible with standard 3/8 inch drive ratchets, breaker bars, torque wrenches, and extensions. Its tether-capable design makes it appropriate for elevated work environments or job sites where dropped-tool hazards must be controlled. The metric 20 mm size is typical in drivetrain, suspension, and structural fastener applications across a wide range of vehicles and machinery.

Compatibility

Designed as a standard OEM-style metric deep socket for use with 3/8 inch drive hand tools including ratchets, breaker bars, extensions, and torque wrenches in automotive, equipment, and general mechanical applications.

Installation Notes

Install and remove using a calibrated torque wrench when fastener torque specifications apply. Ensure the socket is fully seated on the fastener before applying torque to prevent slippage or rounding. Inspect the socket and drive square for wear or cracks before use. Do not use impact drivers with this hand socket unless the tool is rated for impact use.
