Engineered for durability and precision, this high-performance tool is designed specifically for cyclists, bike mechanics, and cycling enthusiasts seeking reliable, efficient hexagonal socket screwdrivers.

Materials & Construction:

Crafted from premium stainless steel, the Wera 3950 PKL features a rust-resistant finish that guarantees long-lasting strength and corrosion protection. The laser-coated surface enhances abrasion resistance, ensuring the tool maintains its integrity even after frequent use in demanding cycling environments.

The Hex-Plus profile is engineered to maximize contact surface within screw heads, significantly reducing the notching effect and minimizing the risk of damaging delicate screw recesses. The 4mm tip size makes it ideal for a wide range of bicycle components, from cranksets to derailleur mounts. The ball-end on the long arm allows for "round the corner" screwdriving, enabling access in tight or hard-to-reach spaces without sacrificing torque or control.

Components & Technology:

Designed with precision-machined tips and a durable laser coating, this hex key provides a secure fit in hex socket screws, ensuring efficient torque transfer and reduced cam-out. The ballpoint end on the long arm facilitates angled screwing, making it versatile for various cycling repairs and adjustments.

Style & Use Case:

This individual metric hex key is perfect for bike maintenance, whether you're adjusting stem bolts, brake calipers, or chainring bolts. Its ergonomic L-handle design provides optimal grip and leverage, reducing user fatigue during extended repair sessions. Suitable for professional bike shops and dedicated cyclists alike, it's the reliable tool you need to keep your bike in peak condition.
