Title: TKO grub screw size
Post by: StevenG on September 30, 2016, 09:42:23 PM

Does anyone know the size of the grub screws used in TKO products? I want some plastic tipped screws to replace the originals.

You may just want to email TKO an ask him. You can probably get more of them straight from him too.

Thanks, I was sure someone here knew.

I did not want more of his, I want plastic tipped scres to protect the barrel finish.

I found if you cut a bit of weed trimmer line and drop it in the hole works well.  I also tried sections of buna orings but they're too soft.

I stand corrected.  I forgot I had to have my TKO screw tapped for 8/32" a couple years ago.  Sorry about the wrong info.

For a second i was thinking brass tipped set screws would work, but they would damage the black and potentially electrolysis react with the steel causing corrosion. I like the nylon idea particularly if you have to remove the brake frequently. The nits on the barrel from the set screws can make removing that brake a hassle. I wonder if Mike has tried this or what he thinks of ithe idea?

The other alternative I have considered is cutting the reducing end section in half and then using screws to hold it together.
That way the whole ring tightens more evenly.

Sort of like a scope ring?

Exactly like that.
