Hex wrenches have become a popular option for many people who are looking for versatile and efficient tools for their projects. This is because they can work with different types of fasteners and provide a good amount of torque for easy loosening or tightening.
However, while that is the general overview, there are several types of hex wrenches, each with its pros and cons. So when going to get one, it is important to know what kind of projects one will be using them for and then select the tool that is best suited for those tasks. Below are the various kinds of hex keys and wrenches and their features.
These are some of the most popular hex wrenches because they come with lots of keys for different sizes. The keys usually range from the smallest to the biggest, and they can tackle all hex socket screws and bolts. Moreover, they come in varying sizes – 4 mm to 10 mm – and are usually made of durable steel alloys.
A short-handled hex wrench is good for people who want to work in tight spaces. These wrenches are only about 2-3 inch long, so they can easily go into any small openings. But since the wrenches are short, it will take a lot of effort because they cannot generate torque. So these are best suited for garment repairs, mobile phone repairs, and other small gadget fixes.
On the opposite end are the long-handled hex wrenches. Their long arm makes it easier to use them for heavy-duty tasks because they can easily build torque. They usually come in lengths of 4-8 inches and are made from chrome-vanadium alloy steel or carbon steel. So it makes sense that they would be the most suitable for automotive repairs, machinery service, and large equipment maintenance.
The T-handle T-handle socket tool and foldable wrenches are good middle-ground options. They provide flexibility in that they can do both small and large projects to some extent. The T-handle wrenches look like a 'T' from the top while the foldable ones are the compact versions that can fold. It is, however, not as portable as other kinds, being about 4-5 inches long, with some extending handles. These tool wrenches are good for medium to heavy servicing jobs like drone service and bicycle repair.
Hex wrenches are a necessary tool that many people need to have in their toolbox, but how exactly does one go about choosing the right ones? Well, there are several factors to consider. Below are some of them.
Material
When it comes to selecting hex wrenches, it is always a good idea to look at the material it is made from. For instance, chrome-vanadium alloy steel is strong and has good corrosion resistance. That is, it does not rust or wear down easily, making it a good option for repairs and maintenance.
On the other hand, carbon steel has higher wear resistance and does not cost as much, so it is used on wrenches that are focused for more general and light-duty work. Finally, there is the chrome-plated finish. This one is obvious because it gives a layer of protection against rust and corrosion.
Size and range
This is probably the most important factor since one is likely to get fasteners in many different sizes. So,【a】hex key sets are handy because they come with multiple keys in varying sizes. That means they can tackle just about any hex socket screw or bolt around. Also, short and long hex wrenches are good to have because they cater to specific needs for small or tight spaces and heavy-duty jobs, respectively.
Handle design
A handle looks simple, but it makes a difference in how much torque one is able to achieve and more – working comfortably. Hex wrenches, for instance, have a 'T' shaped handle, which gives it better grip and torque when turning it. Like foldable ones, it is easy to carry them around, but they are longer – which negates the portability. So, when getting a hex wrench, the handle design will have to be considered to ensure efficiency and comfortability.)
Automotive industry
Hexagonal wrenches are used to fasten and unfasten the many different types of bolts and screws found in vehicles. For instance, they help the mechanics work on engines, transmissions, and other components. Also, they are used in the assembly and disassembly of parts such as wheels, brakes, and suspension systems.
Furniture assembly
Furnitures, like chairs and tables, come with hex screws to make their at-home assembly easy. The furniture industry also uses a hex screw driver or wrench to secure parts during manufacturing and shipping. This helps keep products stable and secure as they move and are eventually set up at the customer's home.
Machinery and equipment maintenance
In factories, people have to deal with a lot of machinery and equipment. Hex wrenches are used to work on all the bolts and screws in these machines, making them a must-have for all maintenance and repair in industrials. How else would people disassemble or fix things without these wrenches? Precisely. They provide mechanical workers with a means of doing effective commercial operations.
Bicycle repair and servicing
Of all the hand tools, the metric hex wrenches are the most used in bicycles. Things like the seat, handlebars, and wheels have hex bolts and screws. There are a lot of hex wrenches laying around repair shops. After all, they have to keep bicycles running well so that the customers have good service.
Electronics assembly and repair
Consumer electronics such as computers, smartphones, and other devices all have small components that need to be fastened with screws. Hex wrenches are the go-to tools in this industry as they are used for assembling and servicing electronic products. Electronics have really detailed and tiny components, so a short hex wrench is the best way to go when working in those little spaces.
To get maximum performance, it is important to understand the specifications of the hex key sets and how to take care of them. So, here are the details.
Length
Usually, there are two types of lengths available – short and long. The former is usually around 2-3 inches in length, while the latter is around 4-8 inches. Choose the shorter ones when working in cramped spaces, and take the longer ones when there is enough room and extra torque is needed.
Angle
They, of course, need to be bent at 15 degrees in order to work well. This angle enables them to slide into tight spaces while still giving a long enough surface to grip. It is also this angle that prevents the wrench from rounding off fasteners.
Surface finish
The most common surface finish for a hex wrench is chrome plating. This is because it protects the wrench from both rust and corrosion. It also makes it smoother for the user, which makes it easier to clean. Other finishes include black oxide or nickel plating. They also operate like chrome but offer less reflectivity.
Storage case
As for the storage options, people can often find them bundled with their set. They include a plastic holder, a pouch, or even a rack. These cases help keep the wrenches organized by size so they are easy to find when needed. Furthermore, they also help to prolong the overall life of the wrenches by about a few months or so since they keep them protected from external elements such as dust and moisture.
Cleaning
As mentioned earlier, maintenance is crucial. A good starting point is always to wipe it down after every use. This will be cleaning off dirt, grime, and any kind of debris that would be damaging if allowed to stay on for too long. The owner should also wash it occasionally using warm soapy water and a soft brush. The trick here is not to use any harsh chemicals on the chrome finish because, well, they can damage that protective layer.
Prevent rust
The best way to prevent rust and the worst way to treat a rusted hex wrench is to apply a thin coat of oil. This oil would be like a barrier protecting the metal from moisture and other elements. Every so often, one should check for any signs of rust, and if there are any, use a fine steel wool to remove it. Do this alongside the previously mentioned oiling, and the trouble of having to replace rusty wrenches will be no more.
Inspection
Finally, it is worth noting that people should always inspect their wrenches before using them. Look for any signs of wear, damage, or bending. That's right – worn or damaged wrenches are not only difficult to work with, but they also pose the risk of injury if they break while in use.
A1. There are quite a few names other than hex wrenches that have been given to them over the years. These include hex keys, hex socket wrenches, hexhead keys, and allen wrenches. They are all variations that differ concerning the shape and design.
A2. A hex tool or wrench is designed to fasten or loosen hexagonal head screws and bolts. The long side of the L-shape can drive the fastener in deeper, while the short part can provide leverage to rotate it. A great option when working with furniture that has been designed for homeowners with a hex key in mind.
A3. Like any other tool in life, hex wrenches also require some care. People should regularly clean off any dirt or debris that has accumulated on them. One can wash them gently with warm soapy water and a soft brush to clean them thoroughly. In addition, always rubbing a thin layer of anti-corrosive oil after each use will do wonders.
A4. Yes, there are. People will find metric hex wrenches in millimeters, while imperial ones are in inches. They are both sized by the distance across the opposite flat sides of the hexagonal holes in the screws or bolts. So basically, they simply correspondence to the units that are measured in millimeters and inches.
A5. It is simply done for convenience. This folding hex keys and wrenches are compact and easy to stow away. Their collapsibility also makes them simple to pull out and use – thus, they are the perfect portable option for adjustments on the go.
