Wrench Multifunctional Short Arm Tool

Hex key set made of chrome vanadium steel with matter finish. The tool is usually held and twisted by its long arm, creating a relatively large torque at the tip of the short arm; it can also be held by its short arm to access screws in difficult-to-reach locations and to turn screws faster at the expense of torque. Hex keys are used for tightening and loosening hexagonal bolts and other compatible fasteners. Ball hex ends allow up to a 25-degree entry angle to reach around obstructions. Multi-Use: suitable for installing towel bars, repairing bicycles and assembling furniture. Compression Rings which securely holds fasteners
