Clutch Cable Adjuster Thread

[spookefoote1956]

Morning everyone. What's the thread for the clutch adjuster that goes into the GB Burman box please?

Cheers, Chris

5/16" cycle or unf perhaps?

If we're talking the cable adjuster, my GB 52's 1/4" (definitely) x 26tpi measuring the bit o' thread outboard the 'box best I can.
Whether BSC or BSF I can't say. But into 70 year old alloy . . . 'spect either would run in easily, even if the locknut should be a match for the adjuster.
Whether Burman used other sizes too is another Q however!

Cheers Groily, much appreciated

1/4" BSF originally but as mentioned cycle is so close and on old threads easily both will fit.
