Tungsten Posted October 3, 2010 Share Posted October 3, 2010 I already did a search and found nothing... ugh the search thing sucks here Can anyone tell me what the bolt and thread sizing is for the stock wd21 skid plate? I know this was posted before somewhere but now I can't find it. Link to comment Share on other sites More sharing options...
Kingman Posted October 3, 2010 Share Posted October 3, 2010 I want to say it's 10x1.5. That seems to be what almost all of the bolts are that attach the components underneath these things. Link to comment Share on other sites More sharing options...
Precise1 Posted October 3, 2010 Share Posted October 3, 2010 No, the hex of the bolt is 10mm. It must be M5 or M6, coarse pitch from the looks. I have to get under the truck tomorrow so I'll verify and post then. B Link to comment Share on other sites More sharing options...
MY1PATH Posted October 3, 2010 Share Posted October 3, 2010 drill them out and put some large inserts in there. they'll break and crossthread less that way and will be easier use and ez out on(grade 5) if you shear one off. Link to comment Share on other sites More sharing options...
Tungsten Posted October 3, 2010 Author Share Posted October 3, 2010 I don't cross-thread my bolts. I heard about the drilling them out piece before too but I think the stock bolts are sufficient. Keep in mind Japan has a tendency to make things really small but really tough at the same time. Also, they can be drilled bigger later in case anything happens.

Keep in mind Japan has a tendency to make things really small but really tough at the same time. Also, they can be drilled bigger later in case anything happens. I've sheared em off a few times. I run a very small drill thru em and they usually spin out the outher side. Its just easier to stay center on a larger bolt and so one day I will go larger but larger usually shear in a way that they won't spin when you drill...

Tungsten Posted October 27, 2010 Author Share Posted October 27, 2010 So the M6x1.0x12 bolts with M6 locking washers worked out great but I would not use anything shorter than that. That's all I could find at the Home Depot. The rest of the fasteners were either stolen from the packets or ravaged. Those damn thieves can't spend 50 cents!

sewebster Posted October 27, 2010 Share Posted October 27, 2010 What does the middle bolt attach to at the front? Mine just has a hole there (not rust, seemingly on purpose). Link to comment Share on other sites More sharing options...
Tungsten Posted October 27, 2010 Author Share Posted October 27, 2010 there should be a welded bracket or nut on the other side mine had a thread there before you put bolts in, if they haven't been in there for a while, chase the thread with a M6x1.0 screw tap Link to comment Share on other sites More sharing options...

Watch after 1 or 2 winters they will be rusted to @!*% and break off like mine did. I only have 3 bolts holding mine now. I just used some course thread self tapping bolts.

Tungsten Posted October 28, 2010 Author Share Posted October 28, 2010 (edited) they won't break off, they are stainless steel bolts i'm not planning to drill them out either because longer/bigger bolts like to travel through other surrounding things also they get removed and cleaned with every oil change i had worse fasteners in there before and they did not break off the trick with those things is to get them as short as possible (and don't forget the washer) that way you are required to put less torque on the head to spin the bolt if it is frozen thus decreasing the chance of snapping it off Edited October 28, 2010 by Tungsten Link to comment Share on other sites More sharing options...
