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

Product Information

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. 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. 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 Sizes Size and weight – Allen™ keys tend to be smaller and lighter than the equivalent tools used to apply other fastener types, making them easier to carry. This can be an advantage for applications where mobility is important such as with cyclists that might want to carry a bike tool kit along on a ride.

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.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: 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 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? Non-sparking designs – While most Allen™ keys use an alloy steel or tool steel material in their fabrication, there are options available that utilize Beryllium Copper in lieu of steel. The Beryllium Copper material will not create sparks if the tool accidentally slips and strikes another metal surface. The non-sparking feature of this material makes these types of Allen™ wrenches suitable for use in applications where the presence of flammable gases or combustible liquids might exist.

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

Besides the common types described earlier, Allen™ wrenches are available with other features that improve safety or increase convenience for using the tool.
