I was wondering if anyone out there can give me information on 1/4 inch thread tungsten darts. Ive never come accross any before, un til a set i recently picked up. They are 25 grams in weight and are similar in shape and size as Jim Pike darts, with 6 ring grips (3 x 2). I suspect they're quite rare, but any info or insight on them would be appreciated.

Nope not rare (sorry) lots of darts that are made in USA are 1/4 " threads. That being said I would stick to 2ba threads.

Hello and welcome to the forum, nope they are not rare really, I have lots, check my album in my sig

I think all the early tungstens were 1/4 inch thread.
