Hex adapter Bosch 2609390034 HSS-G 11mm 210mm

The Bosch Hexagon socket adapter HSS-G 11mm 210mm is a ground high-speed steel tool designed to transfer torque between a hexagonal driver and inserts or sockets. With an 11 mm working width and an overall length of 210 mm, this adapter provides an extended reach for fastening and loosening operations in confined or recessed locations. The HSS-G material and precision-ground surfaces deliver consistent geometry and wear resistance suitable for repeated use in workshop and field environments.

Advantages

The adapter offers a combination of durable HSS-G construction and precision grinding that supports accurate fit and longer service life. Its extended 210 mm length increases access to deep-set fasteners while the 11 mm hex interface maintains secure torque transmission. The compact cross-section and straight shank design minimize wobble and improve control during manual or powered operations.

Suitable for

• Reaching recessed or deep-seated screws and bolts
• Use with hexagon drivers, nut drivers, and compatible sockets
• Workshop maintenance, assembly lines, and on-site repair tasks
• Situations requiring a durable, precision-ground adapter for repeated fastening

Key specifications

• Material: Ground High-Speed Steel (HSS-G)
• Hex width: 11 mm
• Overall length: 210 mm
• Finish: precision-ground surfaces for accurate fit
• Intended connection: hexagon driver to socket interface

How to use

Select a compatible hex driver or power tool and insert the adapter into the tool’s chuck or holder ensuring a secure fit. Attach the appropriate socket or insert onto the hex end. Position the adapter so the socket engages the fastener, apply steady axial pressure and operate the tool at appropriate speed and torque for the fastener and application. After use, inspect the adapter for wear, clean debris from the interface, and store it in a dry place to prevent corrosion.

Usage recommendations

For safe and effective operation, match the adapter’s 11 mm hex to the tool and fastener size, avoid excessive side loading, and use appropriate torque settings on powered drivers. Periodically inspect the precision-ground surfaces for burrs or deformation and replace the adapter if wear compromises the fit.
