USAG 280 HG/SE6 – Set of 6 Hexagon Keys (2.5-8 mm) Bi-material

The USAG 280 HG/SE6 set includes 6 hex keys (Allen keys) with an ergonomic bi-material non-slip handle, made of chrome-vanadium steel with a chrome-plated finish and burnished tips for perfect precision and a secure grip even on recessed screws.

The USAG 280 HG/SE6 set is ideal for those looking for reliable and professional tools for precision tightening of recessed hex screws. Each key in the set (sizes 2.5-3-4-5-6-8 mm) features an ergonomic bi-material handle that combines comfort and durability: the non-slip coating ensures a stable grip even in the presence of oil or sweat.

The blades are made of high-alloy chrome-vanadium steel, a material known for its strength and ability to transmit high torque without deforming. The finish is chrome-plated, while the ends of the keys are burnished: this guarantees reduced dimensional tolerances and a perfect fit with screws to minimize slippage.

These keys comply with the ISO 2936 standard, which means they are designed to withstand high torque: in case of overload, they deform instead of breaking, increasing safety during use. The handle design is engineered to offer optimal control and a secure grip even during prolonged tightening.
