BOLT SIZES
-------------------------------------------------------------------------------------------------

**** Eventually all sizes will be in excel with pulldown menu, organized by name, and catagory. This is just a starting point. As I go along with my Cruiser project (s) , I am checking sizes and updating. This list is compiled from the web, LCML, and IH8MUD.

**** Please post any erros, or additional things to add. I have some dates for the different years I am going to add later.

Motor Mount Bolt Size
12mmx1.25x25 is the bolt that holds the cast mount piece to the engine block...
12mmx1.25 is the thread size/pitch bolt that attaches the cast piece bolted to the block to the engine mount.

12x1.25x 35 or 40mm Front and rear mounts
Poser

Driveshaft Bolts
12 nuts, bolts, washers from Dealer.
“The driveshaft bolts have an unthreaded part of the shank where it goes through the flanges. A
regular bolt will have threads that go all the way up from the head. Because of this, the regular
bolt is more likely work itself loose, with the result being your driveshaft disconnecting. Not a
fun experience.So OEM bolts are considered choice. You can get them from online suppliers and
Toyota.”
IDAVE

Note that blue locktite should be used on driveshaft bolts.

HELPFUL TIPS AND OTHER HINTS
-------------------------------------------------------------------------------------------------

How To Clean
You can place the nuts in Mason jars and clean with lacquer thinner or carb dip, and let soak for
about a day. OR you can buy a parts washer and put a removable tray in. Depending on the Cruiser, bolts may have to be replaced, not cleaned, i.e. rusty bolts.

Stuck Bolts
"PB blaster" helps loosen bolts

Determining Bolt Size
Get an electronic caliper and a metric thread gauge

Getting Windshield Screws Out
An impact wrench can be used or a hammer with a screw driving. I used a large screwdriver, then clamped vise grips onto the screw driver. The bolts had been sprayed with WD40. I didn’t have anything else at the time, so WD40 worked fine. The bolts were hard to get out, but once I had a method with my large Phillips it worked well and I got them all out. Others say they heat the screws and spray liquid wrench.

What does the M mean?
Many confuse the M to mean the hexhead diameter, but it is actually the diameter of the bolt (metric thread call out).

-------------------------------------------------------------------------------------------------
WHAT IS JIS?
-------------------------------------------------------------------------------------------------

Good thread on JIS http://forum.ih8mud.com/showthread.p...ght=bolt+sizes

...................JIS............................ ISO/DIN
M6...............10mm head...............11mm
M8...............12mm head...............13mm
M10.............14mm head...............15mm
M12.............19mm head...............19mm

Replacing bolts with non-JIS changes the hex head size of the fastners, which causes you to switch wrenches while working.

Jeff Zepp Comments on JIS
There a number of other sizes that are less common, such as M4 x 0.7mm (screws), M12 x 1.50mm and M12 x 1.25mm (calipers for example), and different lengths than those listed above. Some are very specialized, like the carriage bolts for the stock 40 front bumper, and bolts for the exhaust hangers and such. Note that for JIS sizes, M6 will have 10mm head, M8 will have 12mm head and M10 will have 14mm head. M12 will be 17mm head. Hardware stores generally carry ISO/DIN sized fasteners which will use a 13mm head for M8, 15mm head for M10 and 19mm head for M12. These heads won't fit in a lot of places due to clearance issues on Land Cruisers. Also, they are often not available in the fine and super-fine threads needed for cruiser applications.

Things like the windshield hinges are oval head phillips rather than hex head. Either factory (dealer) or one of the cruiser-specific aftermarket vendors will be your best source for these types of fasteners.
