2012 Prius v Wagon Front Seat Mounting Bolts -14mm, What Pitch?

I hate to not have an answer I just went to the parts.toyota.com site and found 90119A0304. They MSRP at $1.47.

My local Home Depot has the bolt and nut sizer with thread pitch....

From Albany County Fasteners:

"For metric fasteners, thread pitch is used in place of TPI. The distance is also measured in millimeters. To measure thread pitch, use a caliper and measure from the peak of one thread to the next."

In a pinch, you can try to use a ruler with metric markings to see if the threads are 1mm, 1.5mm, 2mm, etc pitch.

Take out one of the bolts you have, check fit with a metric nut (at hardware store), then (assuming you find a fitting one) get appropriate bolts.

 

Any bolt with a 14mm hex head on a Toyota product will be M10x1.25 pitch thread. Toyota conforms with the J.I.S, or Japan Industrial standard.

 

Which begs the question, why do you need new seat mounting bolts? They don't get much wear and tear on them.

 

Grade 10.9 J.I.S flange bolts are readily available from several vendors on eBay. I have a sizeable supply of them that I have acquired over the past 10 years. Jinn Herr is the most prominent supplier of these bolts. They are marked with with the raise letters "JH." on their heads. "WT" is another supplier.

My favorite is an assortment of these bolts in varying sizes an lengths with matching flange nuts in a nice compartmented steel box for around $100 with free shipping. All are ISO grade 10.9. These really come in very handy, A few ones of these bolts pays for the whole box compared to searching for and buying them in small lots individually.

All of them match the thread sizes and hex wrench sizes of the bolts used on all Toyota vehicles.

Everyone who owns and works on his or her Toyota should buy and have this kit on hand. A good example is the M6x1.0c30mm flange bolt that holed the coil on to the car. That is included with this kit. An auto parts store might have this bolt but not with the flange head.

 

@Air_Boss 1 1/2 inch is significant height otherwise I'd share my parents each have one of these type cushions:

In the States McMaster Carr is one go-to name for bolts, and various hardware bits.

 

I am just over six feet. With my 2017 four's fully adjustable seat, I can raise the front of the seat to make it more comfortable. I would like to be able to raise the front of the drivers seat in my 2013 two as well. The back of my legs just above the knee need support. I typically drive Uber for 13 hour stretches, and my knees do hurt after a while.

 

If other family members need to drive the car, then it would be helpful to make this new "adjustment" to the seat quickly and easily reversible. Lets get the data on if it actually helps first.

 

I bought an extend a seat bracket kit back in the day.
