The Tolsen 20048 9Pcs Long Arm Hex Key Set drives hexagonal screws within a 1.5mm to 10mm metric range. With heat-treated CrV steel, it provides 52-56 HRC hardness for high-torque mechanical repairs. A plastic holder maintains organization for all nine pieces during transport.
Key Features
- Heat-treated CrV Steel: 52-56 HRC hardness rating across the 1.5-10mm range. Resists tip deformation under high torque loads.
- Long Arm Reach: L-shaped length for deep-set bolts in industrial machinery. Under heavy pressure, the arm accesses fasteners in cramped housings.
