The package includes three silver square wrenches, suitable for various use cases—backup, storing in multiple cabinets, or sharing with family and colleagues. Made from high-quality zinc alloy, they offer greater strength and toughness than ordinary metal, providing excellent resistance to bending and deformation even under considerable force. The wrenches feature a user-friendly T-shaped design with a D-shaped handle that conforms to the palm’s natural grip, allowing for easier application of force and reducing hand fatigue compared to smaller or less ergonomic handles. Their compact size and lightweight design save space and make them easy to carry on a keychain, in a pocket, or in a tool bag without adding bulk. They are suitable for opening household distribution boxes and small control cabinets, as well as industrial-grade cabinets such as network cabinets and electrical enclosures. They meet a wide range of applications, reducing the need for multiple specialized tools.
