Hex Key Set GEKO G11722 — 22 mm hex key (size 30), steel Allen wrench

GEKO G11722 is a single-size hex key (Allen wrench) specified as 22 mm (marked 30) designed for inserting into internal hex fasteners. Constructed from steel, this tool provides a rigid, compact solution for turning hex bolts and screws where a 22 mm internal hex socket is required. Its simple one-piece design makes it suitable for workshop, garage and on-site maintenance tasks that call for a robust, easy-to-store wrench.

Advantages

The steel construction ensures high stiffness and reliable torque transmission without flexing under normal use. Its single-size format reduces clutter in a toolkit and keeps the tool immediately available when a 22 mm internal hex is encountered. The compact profile allows access in tighter spaces compared with longer levers, and the machined hex geometry provides a precise fit to minimize rounding of fastener heads.

Suitable for

• Mechanical and automotive repairs involving internal hex fasteners
• Assembly and disassembly of machinery and equipment with 22 mm hex sockets
• Routine maintenance, tightening and loosening of large hex bolts
• Toolkits for workshops, garages and service vehicles

Key specifications

• Size: 22 mm (marked 30)
• Type: single-piece hex key (Allen wrench)
• Material: steel
• Finish: machined hex edges for accurate fit
• Form factor: compact, short-length key for tight-space access

How to use

Insert the hex key into the internal hex socket of the fastener so the tool seats fully in the recess. Apply steady turning force in the required direction to tighten or loosen the fastener, keeping the wrench aligned with the fastener axis to prevent cam-out or rounding. For high-torque applications, use controlled, incremental force and, if necessary, apply penetrating lubricant to seized fasteners before attempting to turn them. Store the key in a dedicated slot in a toolbox to maintain its geometry and prevent damage.

Usage recommendations

Use the hex key only on matching 22 mm internal hex fasteners and avoid excessive levering or using cheater bars which can overstress the tool. Inspect the hex edges periodically for wear and replace the key if any rounding or deformation is visible to ensure continued secure engagement with fasteners.
