WHAT IS THE DIFFERENCE BETWEEN FORM A, B ETC WASHERS AND TABLE 3, 4, 7, 8

SOMETIMES A TABLE IS SPECIFIED WHILE SOMETIMES A FORM IS SPECIFIED, ALL VERY CONFUSING

MANY REGARDS

Hi davet1948

Have a look at this website

Had seen something similar, perhaps will pose the question to them i.e what is difference between the schemes forms and tables
Thanks again

This would be so much simpler with a full citation of the controlling standard.

Hi davet1948

I may of misunderstood your question but above the table on the link I posted it gives the differences of the forms A,B,C,D in terms of outside diameter and thickness etc

I'd assume BS 3410 and BS 4320 are a couple of the codes being referenced - just guessing based on Forms and Tables being referenced. DesertFox linked a BS4320 Form chart.

Here's a breakdown of the Tables in BS3410

No I didnt misunderstand your post, my post was what is the difference between the two specs.

Now with Rputvin's post we have the Tabe specs

Many thanks to all

Firstly I said :- "I might havr misunderstood your post" I never said you misunderstood mine.

Your question was what was the diference between form A.B.C. D washers, where in your question does it mention any washer specifications BS3410 BS4310?
Had you mentioned them in your original post I might have answered differently, quoting a TABLE 3,4,7,8 doesnt tell me the specifications.
