Wera 3950 Stainless Steel Ball End Hexagon Allen Key Metric

The Wera 3950 PKL in 1.5mm is the smallest in the range, making it the go-to choice for fine, precision work involving miniature hexagonal socket screws — ideal for instrument assembly, electronics, and small mechanical components.

Constructed from high-grade stainless steel, this key prevents the transfer of extraneous rust to stainless fixings, ensuring a clean, corrosion-free result. The Hex-Plus profile creates a larger contact surface within the screw head, greatly reducing notching and protecting the screw recess from damage over repeated use.

The ball end on the long arm lets you drive at an angle when direct access isn't possible, saving time in tight or awkward spaces.

Features and Benefits:
• Stainless steel construction prevents extraneous rust on stainless fixings
• Hex-Plus profile protects screw recesses and extends screw life
• Ball end on long arm for angled "round the corner" screwdriving
• Metric sizing
