Implant grade ASTM F136 titanium curved barbell fits any of our threadless tops on one end while the other end has a fixed ball. Threadless hole is 0.55mm, pvd plated when colored.
Note on 6mm lengths: your threadless pin top may need a 1-2mm snip to shorten it enough to sit all the way into the post. The other end also has a threadless pin welded into place and the total length is only 6mm inside for both pin lengths to sit.
