Hex Key KS Tools 151.2114 Metric 1 pc Chromium-Vanadium Steel

The KS Tools 151.2114 Metric hex key is manufactured from chromium-vanadium steel and provides a combination of strength and precision for turn and torque applications. With a long arm of 22.9 cm and a short arm of 7 cm, this single-piece L-shaped key is intended for metric hex fasteners and offers a balance between reach and leverage while weighing 260 g for a robust, stable feel during use.

Advantages

The solid chromium-vanadium construction improves durability and resistance to wear under repeated torque. The long and short arms provide versatile leverage options: the long arm increases reach and torque, while the short arm allows compact access in confined spaces. The single-piece design reduces play and increases contact accuracy with hex fasteners, helping to minimize rounding of fastener heads.

Suitable for

• Assembling and disassembling machinery and equipment with metric hex sockets
• Automotive maintenance tasks requiring extended reach or higher torque
• Workshop and field repairs where a reliable single L-shaped hex key is needed
• Precision tightening where controlled torque and accurate fit are important

Key specifications

• Material: Chromium-vanadium steel
• Long arm length: 22.9 cm
• Short arm length: 7 cm
• Weight: 260 g
• Metric hex key format (L-shaped, single piece)

How to use

Select the correct metric size of the hex key for the fastener to ensure a snug fit. Insert the short or long arm into the hex socket depending on required torque and reach: use the long arm for increased leverage and access to recessed fasteners, or the short arm for tighter spaces and greater control. Apply steady, even force to avoid sudden slips; reverse direction to loosen fasteners. After use, wipe the tool clean and store in a dry place to prevent surface corrosion.

Recommendations

Use the long arm when higher torque or extended reach is needed, and the short arm when working in restricted areas. Avoid applying excessive impact force; employ a torque-limiting method if precise torque values are required. Regularly inspect the hex ends for wear and replace the tool if rounding or deformation appears.
