Bolt-Shaped Stainless Steel Top — Internal 1.2mm

If you're looking for a fun alternative to plain stainless steel balls for your 12g or 14g internally-threaded body jewelry, you'll love these bolt-shaped ends! Each bolt end for internal body jewelry measures 4mm across and has a 2mm-long post with a 1.2mm internal thread pattern seamlessly attached to it. The bolt top and the post are machined from a single piece of surgical stainless steel, so they're securely fused together.

Please note that these bolt-shaped tops for internally-threaded body jewelry are sold individually and separately from our dermal anchors, labret studs, surface barbells, and other body jewelry shafts and anchors. They will work with any of our 12g or 14g internally-threaded body jewelry as long as it has a matching 1.2mm internal thrad pattern, so pay attention to the threading when purchasing hardware to go with these bolt shaped body jewelry tops.
