Hello All

=20

I have a BJ7 and have been told (by AH Spares) that the windscreen =
screws
are 2BA.  That is similar to No10 UNF so that is what mine now are.

=20

No 6-36 sounds as if it is very similar to 4BA which is 0.142 inch =
diameter,
38.5 threads per inch.  BA (British Association) threads are widely used =
for
threads less than =BC 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.

I suspect that the windscreen screws referred to as No 6-36 are actually =
4BA

Regards
