Wera

Wera is one of the benchmark brands in the premium European hand-tool market, consistently cited alongside Wiha and PB Swiss by professional mechanics and serious DIYers. The brand is best known for its Hex-Plus drive geometry — a proprietary modification of the standard hex profile that increases the contact area between key and fastener, reducing the notching and cam-out that eventually damages socket-head cap screws. Wera publishes steel alloy and hardness specifications for most products (S2 tool steel, 61 HRC) rather than relying on marketing-language designations like "premium alloy." SDS documents are not available or required for alloy-steel hand tools.
