Trying to identify a machine screw.

Certainly not metric ... can anybody help identify the thread ...

OD is 0.156" so assume its a 5/32"

Pitch is 36

That is a fine pitch


Only thing I can find that matches is No #8 UNF not sure if I can get
one of those in UK (feel free to point me somewhere if you know)

UNF looks to be the closest. You can get them from
