Bell Housing Nut Size

[Paroor]

Hi Chip Hellie, We are talking about a bolt with 32mm length ad a diameter of 8mm having (a pitch of )one thread for one mm. In English we say so many threads per inch, what we understand by pitch. In Europe we consider the advance of the thread by one rotation. It is in this case one mm. Things are easier if we stay only with mm (metric). Another point where I get confused is about miles/gallon. In metric we say how many litter of fuel one car need to cover 100 kM. So can see that in the sales prospect. With the MG TC we can say it need about 10 litter petrol to cover a distance of 100 kM. So we people are different. we think different. We eat different. But we all drive MG-T A, B or C.

April 2005 20:49 Hi, I don't think the bolts are really 8X1.0mm are they? I think that would be a bolt 8mm dia. with a length of 1mm which is about 2 threads? I assume you're talking threads per inch, 1.0 as apposed to 1.25 or 1.50, right? Chip Hellie Dazed and confused (not really)

Chip - almost right. Metric bolts are measured in thread pitch. If you think in inches, a 8X1mm bolt would have 25.4 threads per inch Charles Hill Chip Hellie wrote:

Chip Metric bolts use "Pitch" as opposed to threads per inch (corase or fine) and there appear to be 3 pitches 1.0, 1.25 and 1.5 finest, fine, coarse. Joe [Non-text portions of this message have been removed]

They get coarser than 1.5 pitch (1.75, 2.0, 2.5, etc) at larger diameters (M12 to M20 for instance).

Hi Madhu, I'm just use to buying metric bolts for my Roadracing Yamaha's and when you buy a screw or bolt for them the first number (8) is thread diameter, the second number (1) is the length. Then you need to know the pitch.(1.5) or whatever. I guess old MG's use a different system than the Japanese. Chip --- Paroor paroor@t-online.de> wrote:

Maybe so. A typical metric bolt specification would be M8 x 1.25 x 30 for 8mm dia, 1.25 mm pitch, 30 mm long. -----Original Message----- From: mg-tabc@yahoogroups.com [mailto:mg-tabc@yahoogroups.com] On Behalf Of Chip Hellie Sent: Tuesday, April 19, 2005 7:37 PM To: Paroor; Roger Furneaux Cc: .T-ABCs Subject: Re: AW: [mg-tabc] Bell Housing Nut Size Hi Madhu, I'm just use to buying metric bolts for my Roadracing Yamaha's and when you buy a screw or bolt for them the first number (8) is thread diameter, the second number (1) is the length.
