1HD-T oil sump bolt sizing?

[truK]

Hi there, does anyone know what the size of the engine sump bolt on a 80series 1HD-T engine is? Or how i measure it?

Im trying to work out which size would be appropriate: Magnetic Sump Plugs (http://www.filterplus.com.au/MagSumpPlugs.htm)

Thanks

wheres the metal in your oil coming from?

i dont get any large bits of metal when i dump the sump oil...just interested in getting a magnetic bolt to see if there are any really fine bits (too small to get caught in the oil filter) floating around in the oil thats all
