Engine Bolts Sizes

Recommended Posts

Anyone know all the different size bolts used in the IS200 engine bay ( E.G M5,M6 10,15,20mm etc etc)? as i need the right sizes to order some new anodised bolts, as im trying to replace as many bolts as possible with those anodised 1 (may even get some glow in the dark 1 too, hehe :whistling::whistling: ), so any help will be very grateful, maybe Matt C, Paul, Chris can help here..hehehe :) :) :) :)

majority that i had replaced are M6 and i used 15mm length.. i replaced all the ones on the front (above rad area) the bolts for the fuse box etc, and bolts holding on various covers..

be aware though that the anodised bolts are alluminium so be careful what bolt you replace..

i believe what he means that as the anodised bolts are aluminium they are of course of a lower strength than a steel bolt ( unless you are taking about high grade specialised aluminium, which the aluminium bolts wont be)

will TITANIUM bolts be stronger than anodised bolts guys?

yes stronger, but can be more brittle than alu bolts but as you are only doing the accesory type bolts then no need to really use them - unless you want to that is! oh they wont rust either, ut providing the anodising is good they wont corrode either. - or just go for stainless bolts instead!!

Maz, bit of advice for you and anyone else as you are changing just the normal bolts and may never do this - but just a tip

NEVER put a stainles steel bolt and a stainless steel nut together without any form of lubricant ( oil etc) as they will bind together and you will never get them undone again!

hey i used to work for a Toyota Forklift Dealer and they sell rust proof bolts

most are metric fine like m6 m8 m10 m12

if you dont want your bolts to rust

check it out with a Toyota Forklift Dealer

usually the last 5 digits tell you the size and length ie -61020 10mm thread & 20mm long the first digit is the make up of the bolt

might be some help

Hello Daz and welcome to the LOC.

Tried to find it for you on the parts database but nothing coming up, if you remove the remaining bolt the size is normally stamped on the bolt head or take it to a local engineering company who will be able to match it for you.
