Figure 1 – The cross-section of an Allen™ key showing the measurement for width across flats Types of Allen™ Wrenches Straight hex keys These resemble screwdrivers and function in much the same way except the head features either a flat or ball ended hex key, instead of the traditional screwdriver bit. There are a number of things to take into account when choosing the right hex key for the job, below is a few of the main points of consideration.

Access to fastener **- Operating in tight working environments can result in limited access to the fastener you're working on. Ball-end hex keys allow for tightening and loosening of fasteners at a variety of angles, so if you're working in places where space is limited they might be the answer to your troubles. Torque needed **- When tightening or loosening a fastener (particularly loosening) the amount of torque needed to move the part is key. An L-shape or T-handle have particular leverage in this area, their extended handles allow for greater torque when dealing with fastenersRange of access – Allen™ wrenches that feature a hex ball end can allow fasteners to be accessed from angles other than directly in the same plane as the fastener. This can simplify assembly & disassembly in close quarter conditions.

Figure 1 below shows the cross-sectional profile of the Allen™ wrench or Allen™ key. The important parameter that establishes the size of the Allen™ wrench or Allen™ key is the width across flats, which is the distance between any two of the faces of the tool that are parallel to each other. Did you know that most people use the wrong screwdriver for the job? It’s essential to distinguish between the various screwdriver types and know what screw you’re using. A set from Halfords will include a variety of screwdrivers for slotted head screws, Phillips drive screws and Pozidriv screws, perfect for any job. Impact drivers & screw bits Allen™ screws and wrenches are not the be-all-end-all in the world of fasteners and tools. Some complaints focus on the tool size being too small to allow for one to apply sufficient torque in all cases. Also, inferior materials used in the manufacturing of either the wrench or the screw can render them easy to damage in spite of the increased number of pressure points. But they are still popular more than 100 years after William G. Allen™ filed for his patent and will likely be here to stay for the foreseeable future. Summary Hex keys are available in many different sizes and in both imperial and metric measurements. The size needed will depend on the size of fastener you're working with.Allen™ wrenches are available as individual keys of a given size but are also sold in sets that contain a range of standard sizes. Allen™ keys are identified as being either metric-sized keys in millimeter sizes or SAE (Imperial) sized keys in fractions of an inch or decimal equivalents. This article will present information on Allen™ wrenches, what they are, their advantages, and the common sizes that are available in the marketplace.

Allen™ wrenches or Allen™ keys are generally available in several different styles or types. The most common Allen™ wrench type is the one mentioned earlier – the L-shaped hex key – but there are other variations that incorporate different handle designs, utilize different materials, or add special features. A summary of the most common Allen™ wrench types is found below: Hex keys also referred to as Allen keys or Allen wrenches are used in the application of loosening and tightening hexagonal fasteners. They are used in a variety of industries and are also a handy domestic tool with many uses. They are available in a number of different sizes with both imperial and metric variations available.
