    Default Metric tool conversion

    Guys - I don't have a complete set of Metric tools.

    I'm trying to figure out what size Metric socket I need to remove a bolt.

    When I measure it with a set of Calipers, I get 1120 or (1100 and 20/1000)

    I tried searching on the net for conversion charts with out luck.

    Does anyone know what size socket or wrench I need to buy?

    Thanks,

    RGood,

    That does not make any sense to me and I live in a country which uses metrics. I am not sure what you are measuring or what standard you are using it is a mystery.

    However, that aside I can help you with the conversion. 1in = 25.4 mm and 1 foot = 305 mm or 30.5 cm; other approx wrench sizes are 1/2 = 13 mm; 9/16 = 14 mm; 3/4 = 19 mm; 7/8 = 22 mm. You can figure it from all that.

    You need to get a cheap caliper set with both metric and imperial measurements on it. Plastics calipers can be found for a buck.

    If you turn the 12" adjustable Wrench over, it says 300 mm on the other side!

    1.120 inches is 28.45mm so it sounds like you need to get a 28mm socket?

    You could use a 1-1/8" socket for that. 1.120" is only .005" less than 1-1/8" which is about normal for that size.
    If you get a 28mm socket (1.102") it will be .018" too small, or 1/2mm small IMHO.

    I would not want someone to be mislead by this table. It is not correct. I often use 1/2 in wrench for a 13mm nut and 19 mm is very easily worked with a 3/4 in. The problem is the rounding off of standards has resulted in errors in the extrapolated measurements. 1 inch is 25.4 mm and 12 inches is 305 mm. Those are close for making estimates.

    I had a mental block and could not see that that only the "." was missing and I should have read 1.120. Opps. I will blame the late hour for my error.

    3RRL is right in that a 1 1/8 in socket will work well.
