RedM Posted October 3, 2007 Share Posted October 3, 2007 What is meant by Table 1, table 2, 3, 4 etc? What differences are there between the different tables? Can you believe that, in a company that's existed for 25 years an sell millions of washers each year, no-one knows! Link to comment Share on other sites More sharing options...

Havard Posted October 3, 2007 Share Posted October 3, 2007 I am guessing here Martin that it will refer to the thickness and subsequent strength of the washer. Pipework flanges have a similar system that related to the thickness and maximum pressure. also the size of the holes to suit bolts were determined by the table etc!! Or I could be full of shit!! H.

RedM Posted October 3, 2007 Author Share Posted October 3, 2007 Yes it is it's thickness. Are you sure? We sell hundreds of different washers. Some are different tables but of the same thickness and ID/OD!! Even our suppliers can't seem to answer us. Link to comment Share on other sites More sharing options...
jamesmark Posted October 3, 2007 Share Posted October 3, 2007 Sarah's dad is a mechanical/electrical engineer of 40 years so I think I trust his call. Unless it is something different. Link to comment Share on other sites More sharing options...

Digsy Posted October 4, 2007 Share Posted October 4, 2007 British Standards BS 4320:1968 is the "Specification for metal washers for general engineering purposes. Metric series". The tables therein are: Table 1: Bright washers (BZP) - Normal diameter. Metric Series. (Forms A and B). Table 2: Bright washers (BZP) - Large diameter. Metric Series. (Forms C and D). Table 3: Black washers - Normal diameter. Metric Series. (Form E). Table 4: Black washers - Large diameter. Metric Series. (Form F). Table 5: Black washers - Extra large diameter. Metric Series. (Form G). Table 6: Nonminal dimensions for sizes greater than M68 Some of Ricky's table numbers come from BS 3410, which is almost obsolete. Whoever is asking you, I'd ask them which standard they are referring to. Link to comment Share on other sites More sharing options...

RedM Posted October 4, 2007 Author Share Posted October 4, 2007 We have a definitive answer at work. All four pages of it! Some of you are partly right. None of you are wholly right. When we've squished it down so that it's readable yet still make sense then I'll post it up. Link to comment Share on other sites More sharing options...
