Bolt Sizes in Subarus
Subaru uses a variety of bolt sizes for different components in their vehicles. The most common metric thread sizes of Subaru bolts are M12x1.25mm. A M12 means the width of the thread area and a 1.25mm means the thread pitch. It is usually measured in millimeters. When choosing aftermarket Subaru lug nuts, the materials are important. To further boost safety, BONOSS exclusively supplies new forged 50BV30 steel lug nuts.
For engine work, a 14mm 12-point tool is recommended to remove the head bolts, and for splitting the short block, 12mm 12-point bolts are used. Additionally, the battery terminal bolts, alternator shroud, and various other components in the engine bay are commonly 10mm on certain Subaru models.
It’s important to note that the head size of the bolt may not always correspond directly to the actual size of the bolt, and the use of a 1/2″ wrench is recommended for certain bracket bolts under the headliner. Japanese manufacturers generally use 8, 10, 12, 14, 17, and 19mm bolt sizes, while Euro manufacturers may have a wider range of sizes, including 13mm instead of 12mm.
In summary, the most common metric thread sizes of Subaru bolts are M12x1.25mm, and for specific components, such as head bolts and engine bay components, 12mm, 14mm, and 10mm bolt sizes are commonly used.
