Hi, I'm trying to find a couple or four replacement screws for my pillar drill. I measure them as 3.18mm / 1/8 inch at 40tpi But what thread? I've tried downloading some charts from the downloads section but nothing seems to be there? What happened to those? Then comes finding a supplier.....I like Precision Technology Supplies www.pts-uk.com but can't see anything I recognise (not surprisingly for me) Help.....are 1/8 CS screws so hard to find in the UK? |
Darren:
According to this chart I think I'm looking for BSW? But not certain at all......http://mdmetric.com/tech/tict.htm Oh give me metric any day..... :doh: |

5-40 UNC has a 1/8 inch major dia. Might be that. Not sure how to tell at that size. http://www.gewinde-normen.de/en/unified-coarse-thread.html |
Darren:
Yes I see that in my chart too, maybe they are identical..... But this is a 60's British product, I'm guessing we didn't use American threads? |
