Allen Wrenches, also called hex keys, Allen keys or hex wrenches, are six-sided L-shaped wrenches designed to drive hexagon-shaped recessed holes. At AlbanyCountyFasteners.com, we offer a comprehensive range of high-quality Allen keys to meet all your fastening needs. These versatile tools are essential for socket cap and socket set screws found in mechanical equipment, bicycles, engines, and assemble-it-yourself furniture.

Yes. A hex key is a generic term for this type of tool while "Allen key" and "Allen wrench" refer to the Allen brand that popularized it.

High-quality screwdrivers to complement your Allen keys. Our bestselling screwdrivers ensure you're prepared for any fastening task, from precision work to heavy-duty applications.

Allen wrenches are sized based on the diameter of the wrench. They can be in sizes as small as 0.028" to sizes as large as 1" in diameter.

Allen keys, or Allen wrenches, are simple tools used to drive screws and bolts with hexagonal drives or sockets. Socket Cap Products, such as socket set screws and socket cap screws, are predominately driven with Allen keys.

We know of a few DIY options that exist that you could use in place of a standard Allen wrench hex key. One option is to find a flat head screwdriver that fits tightly across the corners of the hex drive. You could also use a Torx or Star drive bit or screwdriver that fits snuggly in the hex drive to turn it. A hex head bolt could also work if you find one with the right head size. We don't generally recommend these options, but if you don't have a hex key on hand, they can help out in a pinch.

The use of black alloy steel in our Allen keys provides an optimal balance of strength, durability, and corrosion resistance. This material choice ensures that our tools can withstand frequent use in various applications, from DIY projects to professional mechanical work.

Ultimately, absorption of electromagnetic radiation requires the generation of the opposite field, in other words, the field which has the opposite coefficient in the same mode. A good demonstration of this is color. If a material or matter absorbs light of certain wavelengths (or colors) of the spectrum, an observer will not see these colors in the reflected light. On the other hand if certain wavelengths of colors are reflected from the material, an observer will see them and see the material in those colors. For example, the leaves of green plants contain a pigment called chlorophyll, which absorbs the blue and red colors of the spectrum and reflects the green. Leaves therefore appear green, whereas reflected light often appears to the naked eye to be refracted into several colors of the spectrum (i.e. a rainbow effect).

By relying on this method, physicists are able to determine the properties and material composition of an object by seeing which frequencies of light it is able to absorb. Whereas some materials are opaque to some wavelengths of light, they transparent to others. Wood, for example, is opaque to all forms of visible light. Glass and water, on the other hand, are opaque to ultraviolet light, but transparent to visible light.

[/caption] Those who can remember sitting through elementary science class might recall learning that with all matter, light is absorbed and converted into energy. In the case of plants, this process is known as photosynthesis. However, they are by no means the only species or objects that do this. In truth, all objects, living or inorganic are capable of absorbing light. In all cases, absorption depends on the electromagnetic frequency of the light being transmitted (i.e. the color) and the nature of the atoms of the object. If they are complementary, light will be absorbed; if they are not, then the light will be reflected or transmitted. In most cases, these processes occur simultaneously and to varying degrees, since light is usually transmitted at various frequencies. Therefore most objects will selectively absorb light while also transmitting and/or reflecting some of it. Wherever absorption occurs, heat energy is generated.

As already noted, absorption depends upon the state of an objects electrons. All electrons are known to vibrate at specific frequencies, what is commonly known as their natural frequency. When light, in the form of photons, interacts with an atom with the same natural frequency, the electrons of that atom will become excited and set into a natural vibrational motion. During this vibration, the electrons of the atom interact with neighboring atoms in such a way as to convert this vibrational energy into thermal energy. Subsequently, the light energy is not to be seen again, hence why absorption is differentiated from reflection and transmission. And since different atoms and molecules have different natural frequencies of vibration, they will selectively absorb different frequencies of visible light.

The short side of a hex wrench is used when more torque is required, and the longer side is used for length. The long side can also be used to fasten socket cap screws in deep recessed holes the short side cannot reach.

In short, yes. At least as far as just drive design goes. It mostly has to do with drive angles, which is how much you have to turn the driver to turn the fastener. Hex drives have a much larger drive angle (60 degrees) than Torx/Star drives (15 degrees), leading to a greater chance of hex drives stripping out. The smaller drive angle on Torx drives form a much tighter tolerance with the Torx driver, better distributing the concentration of force throughout the drive much better than hex drives do.

Whether you're a DIY enthusiast or a professional contractor, we have the Allen keys and related products you need to get the job done right.
