seat belt/harness anchorage?
evening all,
is there anything wrong with using m12 captives rather than 7/16ths stated in the book, had a quick gander at the iva manual thinggy and cant find anything relating to the thread or size of the bolt, what would you guys suggest? Ta Very Much JakeH

7/16th is standard for seatbelt mounting bolts. Why do you want to use M12s?

Just high tensile ones. 8.8 or higher. Not sure about the thread though personally, which is why i went with the 7/16s

7/16 UNF(unified national fine) is the standard used.This is obviously a fine thread.You can also get UNC(unified coarse).There is a genuine reason for using a fine thread although i cant remember what it is/was.
Personally i would go for the 7/16 UNF or if you cant get them then go for M12 in a fine pitch,M12 by 1.50 pitch as opposed to the standard M12 by 1.75.Although probably easier to get the UNF thread than a metric fine.(8.8 tensile strength or 12.9) |

Most belts are supplied with fittings and they are always 7/16unf
