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

Product Information

Long-reach Allen keys are a common feature of most good quality hex key sets, which tend to include a useful range of common wrench sizes and diameters (typically from around 1-1.5mm, up to 12mm and beyond). A ball end Allen key set is also an increasingly popular choice for both professional and hobbyist users alike, and with good reason - ball end hex wrenches (sometimes known as ball end hex keys, or ball point hex keys) offer a far greater degree of versatility and flexibility in terms of access to smaller spaces. They achieve this by dramatically increasing the range of positions the user can stand in relative to the fastener they’re working on at the time. 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. From RS PRO, this high-quality hex key set is a handy way to keep differing allen key sizes all in one place. The L-shaped key has a long arm, and so is ideal for deep-set bolts. Pressure points – the hex design of the Allen™ screw distributes force from the tool against 6 surfaces compared with 4 for the Phillips head screw and 2 for the slotted screw. This makes it easier to loosen or tighten these fasteners and can make it less likely to strip or damage a fastener while loosening or tightening.

Besides the common types described earlier, Allen™ wrenches are available with other features that improve safety or increase convenience for using the tool. Our range of long-reach Allen keys are manufactured by leading brands like Irwin, Stanley, Bahco, GearWrench, Wiha Tools, Facom, RS PRO, and of course the original trademark designer, Allen. How would you use a long reach hex key? 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: 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 SizesIn particular, the T-handle design provides a more comfortable grip than the standard L-shaped hex key, but importantly it can also allow for significantly increased torque (provided the gauge of the hex wrench itself is high enough), because the additional weight of the T-handle acts as a counterbalance that can help to seat the tool more firmly and securely in the head of the fastener. 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. Tether-ready designs – These Allen™ wrenches include an opening on the handle which can be used to attach a tether that can secure the wrench to the user or to a fixed object such as a scaffold. This feature helps prevent the wrench from accidentally falling into a work area and causing injuries or equipment damage. This feature is useful when the tool user is working on an elevated platform.

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: 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. 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: 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? Range 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. The hex key is corrosion resistant and is made from chrome-finished S2 steel, for a long and dependable tool life.
