Tread Bolt is a small. When he's not using his amazing stealth powers to infiltrate Decepticon airspace, he's sneaking up on his fellow Autobot Micromasters and scaring the bejeezus out of them. Even though he sees this as "practice", his comrades in the Air Patrol would rather he let his skills lapse—especially when he shows up, uninvited, in their quarters.
- French name (Canada): Boulon
IDW comics continuity
Tread Bolt was one of the legions of Dead Universe Micromasters who pursued Hardhead and Nightbeat on Gorlam Prime. He survived to confront Hardhead with the Jhiaxus-controlled Nightbeat in the planet's subterranean tunnels, but failed to prevent the Autobot from escaping into the Dead Universe.

- Tread Bolt is a redeco of Classics Jetfire, transforming into a Cybertronic swing-winged fighter jet. It features a removable robot-mode helmet (the side guns becoming blasters mounted on the sides of the nosecone in vehicle mode), the toy's add-on booster packs have flip-out reveal cannons accessible in both modes, and it also features forearm-mounted spring-loaded missile launchers.
- An unexpected level of detail can be found on the gray non-firing rifle; when it is assembled, the gun's "sight" comes together in a way that would be functional on a full-size weapon.
- The paint deco for his alt mode seems to be based almost entirely on that of the U.S Navy Blue Angel Planes.
- Most —if not all— of the toys pictured in the 1990 Hasbro Transformers catalog are unfinished prototypes or mock-ups, and a variety of differences from final product pop up. In Tread Bolt's case, the catalog version lacks the final's "Air Force" tampographs.
