9Pcs Long Arm Hex Key Set(1.5,2,2.5,3,4,5,6,8,10mm)

A 9-piece long arm hex key set refers to a set of hex keys, also known as Allen keys or Allen wrenches, that includes nine different sizes. These hex keys are commonly used for tightening or loosening hexagonal socket screws or bolts.

The sizes included in the set are typically measured in millimeters (mm). The specific sizes you mentioned are as follows:

1.5mm
2mm
2.5mm
3mm
4mm
5mm
6mm
8mm
10mm
These sizes cover a range of commonly used hexagonal fasteners, allowing you to work with different sizes of screws or bolts.

The “long arm” designation indicates that these hex keys have a longer length compared to standard hex keys. This extended length provides increased leverage and allows for accessing screws or bolts in deeper recesses or hard-to-reach areas.
