Vertical starter bolt vibrated its way out - need to know size and length of bolt to replace

The size of the bolts that go on the starter of a 1995 Jeep Grand Cherokee Laredo will depend on the model of starter you are using. In general, most starters use bolts that are M6, M8, or M10 in size.
To determine the size of the bolts you need, you will need to refer to the manufacturer's specifications for your particular starter. You can usually find this information in the documentation that came with the starter, or by contacting the manufacturer.
It is also important to note that the starter bolts may not be the same size as the original bolts that came with the vehicle. If you are replacing the starter, make sure to use the correct size bolts as specified by the manufacturer of the starter. Using the wrong size bolts could result in damage to the starter or the vehicle.

You would need a parts diagram for that specific vehicle to identify each bolt, generally you need a dealership parts catalogue.

It seems overwhelming but it's just a small puzzle. We used to call this a "basket" case.

You are going to need a specific amount of bolts that are the same for each group. Separate the bolts you have into piles of similar lengths and sizes.

Of course you will need to try each bolt hole by hand to prevent installing the wrong threads as well as making sure the bolts you use are the correct length. By determining the length and size you should narrow you hunt down. FOR EXAMPLE: you will need 3 here of the same size and length, 5 there that are long and 2 short, 4 there, etc., Just like you identified the long mount bolt. You can also identify where bolt heads were installed by size and the imprint left from where they were removed.

It's not really that difficult since the bolts are always different lengths and sizes, just don't put a long bolt into a short hole. (measure with a small screwdriver to get the length and make sure your bolt is never longer than the room available and the threads fit.)

Good luck!

lost both?
they are both the same diameter.
the length is super easy, measure it.
the leaves, diameter, metric, 8 or 10mm and pitch
so using a box of random bolts with starter off
find one that fits, m8 or m10, or m12.
now you know the sizes, and with starter off the holes are right there. in front of you to test.
to get length, use drinking straw, and your thumb, nail
to find lenght fitted up by and then move straw to ruler, metric
ahhhhhh there is the lenght in 5min work.

if no bolts in the scrap box, at all, metric, buy some.

Probably 12mm X 1.5mm. Length is about 1 1/2 inches and 3 1/2 inches. They are metric.

you can buy them at autozone,they may even know what size you need. usually starter bolts are the same size and in some cases just the length is different. simply try the one you have in the other hole and if it works then problem solved on the size but the length may still be different.

You should be able to obtain a starter bolt from any auto parts store.

are you asking for the socket size to remove the bolts,if so it takes a 9/16"socket.if you are asking to get bolts to replace them then these are a specific size and strength of bolt.if you don`t want to buy new then go to the wrecking yard and get them.i believe they are two different lengths.

the best and easiest way which will also get you the right ones at the right length is to buy them (by year and model and engine) from a salvage yard.
