windscreen screws are 2BA. That is similar to No10 UNF so that is what
mine now are.<o:p></o:p></span></font></p>

0.142 inch diameter, 38.5 threads per inch. BA (British Association)
threads are widely used for threads less than ¼ inch in all British mechanical
and electrical equipment up to the 1960s and 1970s. They have probably
died out now in new equipment. The largest is 0BA which has a diameter of
0.236 inch.<o:p></o:p></span></font></p>
