Wera 3950 Stainless Steel Ball End Hexagon Allen Key Metric

The Wera 3950 PKL is a premium stainless steel L-key designed for hexagonal socket screws, available in sizes from 1.5mm to 10mm. Manufactured from high-grade stainless steel, these keys actively prevent the formation of extraneous rust — making them the ideal choice when working with stainless steel fixings where tool contamination could cause corrosion.

Wera's proprietary Hex-Plus profile provides a significantly larger contact surface within the screw head compared to conventional hex profiles. This dramatically reduces notching effects and virtually eliminates the risk of damaging the screw recess, helping socket head screws last longer.

The hexagonal ball end on the long arm allows the tool axis to be swivelled away from the screwdriving axis, enabling effective "round the corner" screwdriving in confined or awkward spaces. All keys are metric and supplied individually.

Features and Benefits:
• High-grade stainless steel construction prevents extraneous rust on stainless fixings
• Hex-Plus profile maximises contact surface and protects screw recesses
• Reduces notching effects, extending the working life of socket head screws
• Ball end on long arm enables angled "round the corner" screwdriving
• Metric sizing for compatibility with standard metric hex socket screws
