Looks like good stainless steel. The threads are EVER SO SLIGHTLY crooked, but clean. Its not so bad it’s a big deal. Just add a crush washer to the o2 sensor and you’ll be fine.

If you're looking for a bung to weld for your new exhaust for your 94-97 miata, this is the correct thread size. I welded this to a Yonaka 1.8L exhaust and it fit great. The stepped design makes drilling a hole a lot easier as it does not fall into the hole. Recommended.
