 ====== REF: Hex, Socket (Allen) and Torx Bolt and Screw Wrench Sizes ======
 \\
+With the charts below and knowing or deducing the nut / bolt thread size, you can figure what size wrench is needed. \\
+If you are not sure of the thread size, you can reference the [[http://sportsterpedia.com/doku.php/techtalk:ref:tools020|Hardware P/N & Descriptions]] pages in the Sportsterpedia to find bolt sizes for IH and Evo Sportsters. \\
+And likewise, if you know the wrench size, you can sometimes deduce the thread size (barring course or fine threading). \\
+====== Measuring a Hex Bolt / Nut Size ======
+Let's say you have a bolt / nut you need to remove but you don't know what size wrench to use. \\
+**First and foremost, use the appropriate wrench type (6 point hex requires a 6 point wrench)**. \\
+Using a 12 point wrench on a 6 point hex will eventually result in either rounding the hex corners or stripping / breaking the wrench. \\
+Likewise, if a 6 point wrench even fits on a 12 point nut / bolt, it will not be able to keep enough torque on the corners and will end up stripping them. \\
+You can measure across two opposite flats of a hex bolt / nut with a tape measure or yard stick. But it will not be as accurate as using a caliper. \\
+Either way, get the measurement and choose a wrench that falls in the nearest size up from the hex size. \\
+Wrenches come in standard sizes and most, but not all, hex bolts / nuts are made with standard wrench sizes in mind. \\
+The real trouble comes when companies use "special manufacturing Specs" (most likely so you'll have to buy their tool to fit the part). \\
+In the pic below, an engine sprocket nut from a Buell XB crank was measured at .806" (20.47mm).
+The next size up SAE wrench size is .8125" or 13/16" (20.6375mm).

+When you reference the hex wrench chart below, be aware that using a larger size wrench will increase the chances of stripping the bolt head corners. In some cases, you may want to try using a size above the one recommended in the chart to see if it fits by chance. Not every metric size has a perfect SAE counterpart and vice-versa. There is no perfect substitute for the right size tool. \\
