L-shaped hex key Wera 3950 PKL

Wera 3950 PKL L-shaped hex key for imperial hexagonal socket screws, made of stainless steel to reduce external rust and increase durability. The tool features the Hex-Plus profile, which provides a larger contact surface inside the screw head to minimise notching and significantly reduce the risk of damaging the screw recess. The long arm measures 11.9 cm, giving improved leverage and reach for confined spaces.

Advantages

Stainless steel construction resists formation of extraneous rust and increases service life. Hex-Plus profile increases contact area within the screw head, reducing wear and the chance of rounding the recess. The long arm length provides better leverage and access in tight or deep applications. A hexagonal ballpoint end on the long arm allows angled engagement for "round the corner" screwdriving.

Suitable for

• Imperial (inch) hexagonal socket screws
• Maintenance and repair tasks in confined or recessed areas
• Applications requiring angled screwdriving using the ballpoint end
• General workshop and field service work where corrosion resistance is needed

How to use

Select the correct imperial hex key size for the screw head. Insert the short arm into the screw for maximum torque or use the long arm for reach and leverage. For angled engagement or to reach screws that are not directly accessible, use the hexagonal ballpoint end on the long arm; this allows the tool axis to be offset from the screwdriving axis. Apply steady turning force and avoid excessive torque that could damage the screw or tool.

Usage recommendations

Use the tool with the appropriate size to avoid rounding screw heads. Store dry after use to preserve the stainless steel finish and inspect the hex profile periodically for wear. For maximum torque, use the short arm as the drive and the long arm as a lever when needed.
