AT-010 Hex Key Allen Wrench Set

These hex key Allen wrench sets provide the precise fit and torque capacity needed for socket head cap screws in automotive engines, machinery assemblies and furniture construction. Forged from chrome vanadium steel 6150 and heat-treated to HRC 52-56, each key withstands torque that exceeds DIN 911 standards without twisting or rounding.

The ball-end design on long-arm keys permits working at up to a 25-degree angle in confined spaces where straight insertion is impossible. Precision-ground hex profiles ensure full contact with screw heads, preventing cam-out and damage to expensive fasteners. Color-coded ball ends enable quick size identification, and dedicated organizer cases keep every size neatly stored for instant selection.

Available in compact 9-piece metric sets for bicycle and motorcycle maintenance, as well as full 18-piece metric/SAE combination sets built for professional mechanics. Ideal for auto repair shops, bicycle service centers, industrial maintenance teams and furniture assembly operations that regularly install and remove socket head fasteners.
