Allen Key Set STAHLWILLE 8-piece long hex key set (MPN 43213008)

STAHLWILLE 8-piece long hex key set provides a range of long L-shaped hex keys designed to reach recessed and hard-to-access hex socket fasteners. Each key is shaped to deliver reliable torque transmission and a secure fit, making the set suitable for professional workshops and maintenance tasks where additional reach and leverage are required. The assortment covers commonly used metric sizes in a compact holder for organised storage and quick selection.

Advantages

The long-arm design improves accessibility to fasteners located deep in components or behind obstacles without compromising control. Precision-machined hex profiles reduce rounding of sockets and ensure consistent engagement. The robust steel construction offers durability for repeated use under workshop conditions, while the compact holder keeps the set organised and protects the keys from loss or damage.

Suitable for

• Servicing machinery and equipment with recessed hex fasteners
• Automotive and bicycle maintenance where reach is needed
• Assembly and disassembly in confined spaces
• Professional workshops and industrial maintenance tasks

How to use

Select the hex key size that matches the internal hex socket of the fastener and insert the short or long arm as required for clearance and leverage. Use the long arm for reach and the short arm for higher torque, maintaining straight engagement to avoid cam-out. Apply steady, controlled torque and reposition the key if access space requires a different orientation.

Usage recommendations

Inspect hex key tips before use and avoid excessive force that can damage fasteners. Store the keys in their holder to maintain organisation and protect tips. For applications requiring calibrated torque, use appropriate torque tools and rely on the hex key set for positioning and initial tightening.
