Socket bit 3/4" 21 mm GEKO G14021 — 6-point hex drive

GEKO G14021 is a 6-point socket bit with a 3/4" drive and a 21 mm hex opening. It is made to engage standard 6-sided nuts and bolts and to be used with compatible 3/4" drive tools such as ratchets, torque wrenches and breaker bars. The socket bit is intended for automotive, industrial and general maintenance tasks requiring a secure fit on hex fasteners of the specified size.

Advantages

The 6-point geometry reduces rounding on hex fasteners by providing full-face contact with the flats, while the 3/4" drive ensures compatibility with heavy-duty hand tools able to deliver higher torque. Its 21 mm size matches common metric fasteners, offering a direct fit for repeatable engagement. The bit format allows quick interchange between sockets and drive tools and supports use with torque-controlled equipment when accurate tightening is required.

Suitable for

• Removing and installing 21 mm hex nuts and bolts in automotive repair
• Maintenance and assembly work in industrial settings
• Use with 3/4" drive ratchets, torque wrenches and breaker bars
• Tasks requiring stronger torque application and reliable fastener grip

Key specifications

• Drive size: 3/4" compatible drive
• Hex opening: 21 mm, 6-point configuration
• Intended use: hexagonal nuts and bolts
• Tool compatibility: ratchets, torque wrenches, breaker bars with 3/4" drive

How to use

Select a 3/4" drive tool that matches the required torque range for the fastener. Fit the GEKO 21 mm 6-point socket onto the tool’s drive square until it seats securely. Place the socket over the fastener and apply force evenly while turning to loosen or tighten. When using a torque wrench, set the required torque value and apply steady pressure until the wrench indicates the set value. Remove the socket from the drive when the operation is complete.

Usage recommendations

Inspect fastener and socket contact surfaces before use to ensure a secure fit. Use the 6-point socket for hex fasteners to minimize rounding; avoid excessive impact with torque beyond the tool’s or fastener’s rated limits. When precision torque is required, use a calibrated torque wrench and ensure the socket remains fully seated on the fastener during tightening.
