Bolt Base 1.5mm Metric Short Arm Allen Key/Hex Wrench / M1.5 Hexagon Keys/Wrenches - 1 Key

Product Information

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. 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. Like all hex wrenches, long-reach Allen keys are also sold with a variety of head and handle types for various more specialised applications - these can include: Hex keys have a number of important characteristics that make them particularly well suited to the straightforward, user-friendly fastening role that has made them so popular among operators of all experience levels. These include the fact that hex keys:

Hex key sets with T-handles are especially popular with mechanics and automobile enthusiasts, thanks in part to the fact that the T-handle Allen wrench offers certain user luxuries that standard hex keys don’t. Where the additional access provided by a long-reach hex wrench is needed, you'd use the more elongated side as the ‘driver', and the shorter side therefore becomes the handle that you turn to tighten or loosen the fastener. However, when a hex bolt is within easy reach and there's plenty of space to work in, long-arm Allen keys can also be handy used in the reverse configuration - the longer side can help provide better grip and torque when operating as a handle. What types of long reach Allen keys are available?This chrome-plated hex keys has a degree of corrosion resistance, however, correct storing of your tools will increase their useful life. It is recommended that the tools are stored in a clean and dry environment.

Moving over to the right-hand side, we’ve provided the metric to SAE guide for Allen wrench conversions. Similar to the metric hex keys, the SAE hex wrenches don’t always have a perfect substitute as seen for SAE size 3/16″. Thus, we recommend that those with only a metric Allen wrench set add a separate SAE hex key set to their stable. Substituting Uncommon Hex SizesRange 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.
