The Wera 3950 PKL in 2mm offers a compact yet capable option for working with small hexagonal socket screws in precision applications such as electronics, optical equipment, and light mechanical assemblies. Made from high-grade stainless steel, this key prevents extraneous rust when used with stainless fixings — a critical advantage in hygiene-sensitive or corrosion-conscious environments. The Hex-Plus profile increases the contact area inside the screw head, significantly reducing notching and the risk of recess damage during repeated use. The long arm’s ball end enables angled engagement, allowing you to drive screws even where direct tool alignment isn’t possible.
