How big is hex?
Each hex is 6 miles across. The terrain type shown on the space accounts for the majority of the hex’s terrain. But just because a given hex shows plains doesn’t mean you can’t find a copse of trees there. Plains dominate the space, but the world’s environs aren’t actually broken down into hexes. The hexes are an abstraction.
How to measure a hex bolt?
How to Measure a Hex Bolt. Step 1: Measure Shank. The first measurement that you will need to take is the overall length of the shaft of the bolt. Step 2: Measure Unthreaded Area.

The Ultimate Guide to Allen Wrench Conversions
Sometimes—you just have to improvise when you’re on the job. So we decided to make that a little bit easier for you. If you ever need to lookup an Allen wrench conversion, keep our guide handy so you can reference it when out in the field. We’ve provided the best substitute for popular hex sizes from both Imperial & Metric measurement systems.
Imperial to Metric for Allen Keys
On the left-hand side, we have our SAE to metric conversion guide for hex keys that provides the best substitute SAE Allen wrench for each given metric size. As you’ll notice, there isn’t always a perfect substitute. For instance, Metric size 9 mm doesn’t have an imperial counterpart.
Metric to Imperial for Allen Keys
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.
What is a hex key?
Explained by the geographical and commercial history of the drive type's development, the term "hex key" is best known as " Allen " in the UK, Australia, Canada and the USA (The “Allen” name is a registered trademark, originated by the Allen Manufacturing Company of Hartford, Connecticut circa 1910, now owned by Apex Tool Group, LLC, which was acquired by Bain Capital in 2014), and also in Spain ( llave Allen pronounced with Spanish double L, /ʎaβe aʎen/ ), as "Inbus" in Germany (the term “INBUS” is a registered trademark, originally an acronym for In nensechskantschraube B auer u nd S chaurte introduced in 1934 by the German company Bauer & Schaurte, in 2015 acquired by INBUS IP GmbH, Breckerfeld, Germany), and as "Unbrako" key or wrench in Scandinavia (originally a Pennsylvania company established in 1911, in 2008 acquired by Deepak Fasteners Limited). In Italy, it is known as brugola, for the company Officine Egidio Brugola (established 1926).
What are the features of a hex key?
Features. Some features of hex keys are: The tool is simple, small and light. The contact surfaces of the screw or bolt are protected from external damage. There are six contact surfaces between bolt and driver. Very small bolt heads can be accommodated. The tool allows the use of headless and recessed-head screws.
What size screws are used for hex keys?
Hex keys and screws can be damaged by using a key that is too small for the socket, such as by using a 5 mm key with a 5.5 mm socket. Because hex keys and screws are available in both metric and inch-based sizes (the latter sometimes labelled " SAE "), damage can also occur if inch-sized keys are used with metric fasteners, and vice versa. There are exceptions: 4 mm is nearly 5⁄32 in, 8 mm is nearly 5⁄16 in, and 19 mm is nearly 3⁄4 in, making keys and screws of these sizes interchangeable in practical use. As a result, 4 mm and 8 mm are preferred numbers for consumer products such as self-assembly furniture, since screws of these sizes will not be stripped if fastened with their near-equivalent inch-sized keys.
What is a tamper resistant hex screw?
Tamper-resistant hex screws have a protruding pin in the center of the hex recess that prevents insertion of standard hex keys; as such, they can only be fastened and removed with a special key that has a recess for the pin. A similar "center pin reject" security feature is also used on TORX screws.
When was the hex socket invented?
The scant documentation available indicates that the idea of a hex socket screw drive was probably conceived as early as the 1860s to the 1890s, but that such screws were probably not manufactured until around 1910.
What was the first event to use hexagonal drive?
World War II, with its unprecedented push for industrial production of every kind, is probably the event that first put most laypersons in contact with the internal-wrenching hexagon drive. ( Popular Science magazine would note in 1946 that "Cap screws and setscrews with heads recessed to take hexagonal-bar wrenches are coming into increasing use.")
What is the AF of a hexagon?
Hex keys are measured across-flats (AF), which is the distance between two opposite (parallel) sides of the hexagon.
What is the gauge of a head?
Gauge= (Head diameter in sixteenths of an inch X 2 ) – 2. E.g. 5/16 head times two equals 10, minus two equals 8. The Gauge is 8.
What is the X axis of a chart?
Figure 1.: Chart for imperial measurements. The X axis is the gauge size. The Y axis is measurement in millimeters.
Is the metric system easy to understand?
Though the metric system is a bit simple to understand for the unskilled, it can be a bit challenging if you are not conversant with it or still working in imperial.
Is it hard to size a screw?
Bottom Line. To size a screw is a very challenging thing but there are different types of screws you can use for a wide variety of different tasks. In many situations, you may find it challenging to know the head and the thread available and also the different parts that make up a screw.
Can you put metric and imperial screws on the same box?
Imperial and Metric Screw Sizes. Many companies put both imperial and metric size on the same box of screws which is very helpful. However, when buying online in the United States, most of the retailers do not. The main reason is the title of the product becomes too long and cumbersome meaning something has to go.

Overview
Conversion
Most computers manipulate binary data, but it is difficult for humans to work with a large number of digits for even a relatively small binary number. Although most humans are familiar with the base 10 system, it is much easier to map binary to hexadecimal than to decimal because each hexadecimal digit maps to a whole number of bits (410). This example converts 11112 to base ten. Since …
Representation
In most current use cases, the letters A–F or a–f represent the values 10–15, while the numerals 0–9 are used to represent their decimal values.
There is no universal convention to use lowercase or uppercase, so each is prevalent or preferred in particular environments by community standards or convention; even mixed case is used. Seven-segment displays use mixed-case …
Elementary arithmetic
Elementary operations such addition, subtraction, multiplication and division can be carried out indirectly through conversion to an alternate numeral system, such as the commonly-used decimal system or the binary system where each hex digit corresponds to four binary digits.
Alternatively, one can also perform elementary operations directly within the hex system itself — by relying on its addition/multiplication tables and its corresponding standard algorithms such as long …
Real numbers
As with other numeral systems, the hexadecimal system can be used to represent rational numbers, although repeating expansions are common since sixteen (1016) has only a single prime factor; two.
For any base, 0.1 (or "1/10") is always equivalent to one divided by the representation of that base value in its own number system. Thus, whether dividing one by two for binary or dividing one by si…
Cultural history
The traditional Chinese units of measurement were base-16. For example, one jīn (斤) in the old system equals sixteen taels. The suanpan (Chinese abacus) can be used to perform hexadecimal calculations such as additions and subtractions.
As with the duodecimal system, there have been occasional attempts to promote hexadecimal as the preferred numeral system. These attempts often propose specific pronunciation and symbol…
Base16 (transfer encoding)
Base16 (as a proper name without a space) can also refer to a binary to text encoding belonging to the same family as Base32, Base58, and Base64.
In this case, data is broken into 4-bit sequences, and each value (between 0 and 15 inclusively) is encoded using 16 symbols from the ASCII character set. Although any 16 symbols from the ASCII character set can be used, in practice the ASCII digits '0'–'9' and the letters 'A'–'F' (or the lowerca…

How A Hex Nut Works
- Hex nuts are the most versatile and commonly used nut design. In conjunction with washers and bolts, it connects both metal and wood components to prevent movement. The hex nut design allows for maximum torque and grip in a threaded fastener arrangement. Furthermore, the long length of each side allows for a more extensive surface area and high leverage at the nut when a…
Sizing
- The nominal thread diameter of a hex nut provides the key size. Sizes typically range from 1/4″ to 2 1/2″. Specifying size requires fractional inches rather than numerical. Hexagonal nut dimensions also define in metric sizes. Thread profiles are unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN), and ISO measured thread profil...
Markings
- Markings on hex nut should use an indentation on the side of the bearing surface or embossment on the chamfer of the hex nut for identification. Embossed markings must not extend beyond the nut’s bearing surface. As bolt strengths requirements increase, grades do as well. Radial lines indicate the grade or strength class of English bolts on the head. The actual grade is two lines fe…
Hex Nut Grades
- ASTM A563-A hex nuts are compatible with low carbon steel bolts like ASTM A307, ASTM F1554 grade 36, SAE grade 2, and AASHTO M183. SAE grade 5 and grade 8 nuts are also available in a completed pattern. According to the nominal thickness, hex nuts classify as I type, II type, or thin type. Type I and type II nuts have a class of 8 or higher. The type I hex nut is the most common, …
Materials
- Steel, stainless steel, brass, silicon bronze, aluminum, and nylon are standard materials. Steel, followed by stainless steel, is the least expensive material. Copper alloys such as brass and silicon bronze are the most costly. In very rare cases, process conditions may require the use of exotic materials such as titanium or super duplex steel. Zinc coating and hot-dip galvanizingare …
