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.

This may help you in your measures:
1/8" 6 mm 8" 200 mm
3/16" 7 mm 10" 250 mm
1/4" 8 mm 12" 300 mm
3/8" 10 mm 14" 350 mm
1/2" 15 mm 16" 400 mm
5/8" 18 mm 18" 450 mm
3/4" 20 mm 20" 500 mm
1" 25 mm 24" 600 mm
1-1/4" 32 mm 28" 700 mm
1-1/2" 40 mm 30" 750 mm
2" 50 mm 32" 800 mm
2-1/2" 65 mm 36" 900 mm
3" 80 mm 40" 1000 mm
3-1/2" 90 mm 44" 1100 mm
4" 100 mm 48" 1200 mm
4-1/2" 115 mm 52" 1300 mm
5" 125 mm 56" 1400 mm
6" 150 mm 60" 1500 mm
You will have to separate one side from the other here the way it came out.

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

One of the best util prgm you could ask for for almost any kind of measurement conversion is Josh Madison's convert prgm. It's free and I wouldn't have a computer without it.

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

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.

:eek: 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.
