Footrest Stud.
« on: 28.07. 2016 16:12 »
A nut has come adrift on my footrest stud. (57 A10 Road Rocket) Does anyone know what thread it is please, as it's causing me some confusion. The rod is 1/2 diameter but the thread is 20 TPI. Any suggestions please? Thanks. David.

but the thread is 20 TPI.

1/2 inch and upwards is 20TPI 7/16 can be  20 or 26 TPI
All the best - Bill
1961 Flash - stock, reliable, steady, fantastic for shopping
1959 Rocket Gold Flash - blinged and tarted up  would have seizure if taken to  Tesco
