Product Information

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 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. 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. 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? When removing pedals, you will always be turning the spindle of the pedal towards the rear of the bike.

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. 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. 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

Brands to select for perfect and durable Allen keys:

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. 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? Left and right pedals have different threads, and ensuring you are fitting the correct pedal to each side of your bike is key. 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.

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. There are a few variations of hex keys available, the most common and the one that is synonymous with the tern Allen key is the L-shaped hex key. To help choose the right key for the job we have outlined the most common types below as well as a few of their features and benefits. L-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.

Are Allen keys and hex keys the same?

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?

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.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. 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 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? Don’t get confused by dust caps on the outside face of the pedal – these are used for servicing. Laura Dow / Immediate Media 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.
