Strut bolt size for 2010 Toyota Yaris hatchback

[keeney123]

I am trying to find bolts and nuts for a TRQ strut assembly that I want to buy. No parts dealers online or in person are able to provide this information to me. Even those who sell the strut. These bolts and nuts are the lower ones that go to the control arm/steering knuckle. Any help will be appreciated. Toyota calls out different part numbers for both RH and LH of these bolts and nuts. It ends up as the same part number in their check out. In my case the bolt seems to have a 15 mm dia. that has a step that is not adjustable. It is a fixed bolt. Part number for the bolt is 900109-15001. It is considered a type A in their picture. The nut seems to be the same for all the bolts that are both adjustable and non-adjustable. That number is 90170-15004

Did you somehow manage to bugger up the two originals? If you are thinking that the new strut assembly requires different bolts, it doesn't.

No, I will not be changing my own struts. I have a local mechanic that does that. The car is 12 years old, and it has seen many New England winters. Plus, when I undercoated the vehicle 4 years ago, I did not want to replace the front shocks and they were rusting through, so I hit them with CRC rust converter, and then went over it with 3 M undercoating. I did as far up and down on the strut as I could do. I want my mechanic to be able to just cut off the bolts if he has too. I will be traveling 3000 miles with the car in a few months, and I do not what any problems with the bolts that connect the struts.

Mine are 16 years old and subject to brine and salt 6 months of the year. These are 4 of the most robust bolts on the car. I removed mine 3 months ago to do bearing work and they cracked loose with a breaker bar with ease and the bolts themselves were in excellent shape. Your mechanic should have zero issues removing them giving he'll be far better equipped for the job than I am.

Thank you for your input. It is always good to hear from someone else about these issues. I then will end my search for the correct bolts. They must have been engineered way beyond what I would had expected.
I have no luck, so I am always paranoid of most anything that can fail.
