Brush/Mop/Jag (Bisley/PH) thread and pitch

Recommended Posts

Hi All

Do any of you gents know, or could any of you measure, the thread and pitch of a Bisley/PH style bronze brush thread please?

The one's I've got, and subsequently made my pull-through for, are a Euro thread. The Bisley/PH seem much wider diameter (respectively) but are much easier and cheaper to get hold of!

 

Cheers

I have nothing to measure with, but if you're stuck, I'm in Sheffield. Call in I have a couple of different sizes, one being Bisley.

Nice one, thanks for the offer! What other sizes do you have, are they pretty common?

 

Cheers

The others are a narrower thread, bought from Ebay, no idea how common.  I just wanted a cheaper version to put in my shooting bag.

Diameter approx 7.35 mm (0.29")

Approx 1.0mm pitch, or 25 t.p.i.

(similar to 0BA in pitch, but not diameter)

I believe the "Parker Hale" type is officially 9/32" x 26 t.p.i. which is part of the (very old now) British Standard Brass thread series.  The 0.410 version is different being 7/32 x 26 t.p.i.

The US version is 5/16th x 27 pitch (and takes Parker Hale brushes a bit loosely), and the metric version M8.
