+ | 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. \\ | ||
