Facom 82H.15 Short Allen Key, 15 mm.

Product Information

Size of fastener - probably the most important consideration as the wrong sized key either won't fit the fastener or fit loosely resulting in either damaging the tool or rounding off the fastener making it difficult to remove.

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 SizesL-shaped hex keys The most common type of hex key. The L-shaped key is double ended allowing you to use torque to tighten and loosen fasteners with the short end, whilst the long end can be used in the same way as a straight key. 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? Lastly, there’s one other added benefit to having both SAE & metric hex keys. In the United States, larger metric half sizes like 6.5 mm aren’t standard in most hex key sets. However, the 1/4″ SAE hex wrench will likely work in place of a 6.5 mm wrench. In scenarios like these, use the chart to estimate the correct alternative. You can test different sizes till you find the best match. We do recommend starting slowly to ensure that you don’t damage the hardware. Don’t get confused by dust caps on the outside face of the pedal – these are used for servicing.

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 fasteners 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.Ball end hex keys Ball ended hex keys allow access to fasteners in tighter spaces, giving the user an in creased range of angles from which to access the part thanks to its rounded hexagonal bulb-shaped head. The same is true for fitting, where turning the spindle towards the front of the bike will tighten the pedals onto the crank whatever side the pedal is on. 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. T-handle hex keys The T-handle feature a good grip thanks to the shape of its handle, from where it gets its moniker, allowing for significantly increased torque.

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?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. Left and right pedals have different threads, and ensuring you are fitting the correct pedal to each side of your bike is key. Yes, Allen keys and hex keys are essentially the same tools. They both refer to a type of wrench or tool used to tighten or loosen screws or bolts with hexagonal heads. The term "Allen key" is more commonly used in the United States and Canada, while "hex key" is a more widely used term internationally. These keys are typically L-shaped, with one or both ends featuring a hexagonal shape that corresponds to the size of the hexagonal screw or bolt head. They come in various sizes and are made from durable materials such as hardened steel or chrome vanadium. So, whether you call them Allen keys or hex keys, they serve the same purpose of fitting and manipulating hexagonal fasteners. When were Allen keys invented? Note you always fit or remove pedals from the crank end of the pedal spindle. If your pedals have a bolt, cap or screw on the outside end of the pedal spindle, this is only used to service the bearings. Left vs right pedals explained – what are the differences?
