YUV'S 9V Allen Key Set

Allen keys in this set offer two definite advantages due to their L-shape. You can use the shorter arm when you require more torque to turn a heavily wound fastener. Using the longer arm, you can reach those fasteners that are deeply seated or located in hard-to-reach areas. High-grade Alloy Steel These hex keys are made of high-quality steel to make them durable so that they do not get worn out with long usage. Hardened and Tempered These Allen keys are hardened and tempered to make them sturdy so that they can withstand high torque and to make them resistant to wear and tear.
