Tricks To Find The Right Size Starter Bolt

Undoubtedly, the starter is one of the essential parts of your Ford F150. But, people often end up with the wrong bolt’s size. If you use the wrong bolt, it’ll eventually fall out.

Keep in mind the following tips while selecting the starter bolts for your vehicle-

  • You may find the correct bolt size, but the bolt’s threads don’t fit the hole it moves in. The cables will be permanently damaged, though you can get them in the spot after giving enough force. Stay away from this type of bolt.
  • Choose the one that easily fits into the starter. Avoid any bolt that needs to place forcefully. Otherwise, no other bolts will be able to move back in.
  • Check out if the bolt is cross-threaded. You don’t want it to fall back anyway.
  • Don’t fall in love with the larger bolts, as they won’t even match.
  • Make sure the bolts match the thread pitch, diameter, and length of the original bolts’ grade.

Though the bolt size varies for different models’ years, a standard bolt size is available in maximum speed shops or parts stores. And that is 3/ 8” – 16 X 1-1/ 2” using a 1/ 2” wrench.
