If it's of interest to anybody I have tried to collect specs of different cleaning rod and brush manufactures.
Most manufacturers make female rods. You need male brushes and jags for these.
All .17 & .20 rods I've found are threaded No.5-40tpi female.
Most rods for .22 and larger calibers are No.8-32tpi female - Birchwood Casey, Montana X-Treme, Hoppes, Lyman, Pro-Shot, Bore Tech, and uncoated Dewey rods.
Most shotgun rods are threaded 5/16"-27tpi female.
Outers do a proprietary No.7-32tpi female thread for which they make a No.8-32tpi adaptor - no idea why. Maybe a typo?
Dewey also do a No.12-28tpi male thread for a .270-caliber coated rod.
All Otis pull-through kits seem to be No.5-40tpi.
Parker Hale rods and Dewey coated rods - except their coated shotgun rod - are male.
Dewey SS, Carbon and brass rods are female - except the brass shotgun rod which is No.12-28tpi male.
Dewey also recommend using a .20 rod for .22 bores as their .22 rods are sometimes too tight.
Dewey also lists their .22 coated rod as No.8-36tpi - probably a typo as I've never seen a No.8-36tpi brush.
I would suggest avoiding Parker Hale and carefully choosing Dewey products, and you should have no problems with brushes and jags not fitting your rods, or needing adapters.
