- Traxxas part 3965: Screws, 2.5x8mm cap-head machine (6). Size exactly as printed in Traxxas's parts list; the file is built from that size only.
- M2.5 × 8 mm, shank as a plain Ø2.5 cylinder, ISO 4762 cap head Ø4.5 × 2.5 mm.
- True size, no printing tolerance added.
- Traxxas prints the thread and length; the head is drawn to the ISO 4762 cap head standard (from the catalog's screw page) because the maker gives no head size.
