Applications:. Hex keys or Allen keys are most commonly used to tighten or loosen hex fasteners used in a variety of different applications. Hex fasteners are well known for having a 6-sided blade that helps prevent ‘cam-out ‘ or slipping and rounding the fastener, and as a rule, higher torque can be applied to these types of fasteners. With this in mind, it is essential for hex keys to be able to withstand the amount of torque being applied by being more durable and stronger to ensure that it can loosen even the most stubborn fasteners or tighten up to the required torque spec. These keys are most commonly used by: Automotive mechanics Engineers Production and manufacturing operatives DIY enthusiasts. What sizes of hex keys are available in this range?.

Are hex keys and Torx keys the same?. The main difference between Hex keys and Torx keys is that Hex keys have 6 sides and are shaped hexagonally, hence their name. Torx keys are generally star-shaped with the benefit of adding greater contact points for the fastener, hugely reducing the risk of rounding the fastener, which can be a common issue when applying a large amount of torque. Because of this, Torx keys are more expensive to produce and hex keys in comparison are cheaper and easier to manufacture, bringing the cost to the user down as well. What is the benefit of a short arm hex key?. One of the benefits of using a short arm key is that with another hex key situated on the short end, it means that access in enclosed spaces is made much easier and more manageable, making it a versatile hand tool for a range of applications. Additionally, when comparing this hand tool to a screwdriver handle, much less user effort is required by using a T-handle key because a greater amount of torque can be applied in a comfortable way for the user when tightening or loosening the fastener.
