what size are the grease nipples on headstock etc?

Post by StephenG80 »

Hi - can someone tell me the correct size of the grease nipples on the headstock, brake arm etc. I know they are not 1/8!

Need to get a couple of ebay as they won't hit the minimum order for club spares.

Thanks

I assumed they would be cycle thread ( BSC ) needs to be correct. BSF & BSC 1/4 are both 26TPI but pitch for BSF .0357 pitch for BSC .0385.

Er

0.0357" pitch is 28 TPI as near as makes no difference - I consider 1/4" BSC and BSF to be interchangeable in general application and in particular over the thread length employed in a grease nipple.

I must have miss read the tread pitch for BSF & BSC I saw 26 TPI for both Mick. However both 1/4 sizes do seem to be interchangeable in spite of the thread pitch being slightly different. If what I thought I saw in chats was correct.

Just for fun do an internet search for 2 inch nipples. (A friend of mine had to do a plumbing job).
