The Genie 1263237GT TL Nut, M20-2.5, DIN980, 10, ZAB is a genuine OEM fastener built for Genie S-series telescopic boom lifts and Z-series articulating boom lifts. As a direct OEM replacement, this nut is manufactured to Genie's exact specifications, including thread pitch, grade, and finish, so it installs correctly without any guesswork. Confirmed fitment covers models including the S-60 XC, S-65 XC, S-80 J, S-40 TRAX, S-45 TRAX, Z-40/23N, Z-40/23N RJ, and Z-62/40, among others — cross-reference part number 1263237GT against your machine's parts manual to confirm the correct application for your unit.
Key Features
- Genuine OEM Grade and Finish — Manufactured to DIN980 standard at Grade 10 with ZAB finish, matching the original fastener specification exactly for consistent clamping performance.
- Correct Thread Specification — M20-2.5 thread profile ensures proper engagement with mating components, eliminating the risk of cross-threading or under-torquing that can compromise a joint.
- Direct OEM Replacement — Sourced directly from Genie, this nut installs in the same position as the original with no modification to surrounding hardware or structure.
- Broad Boom Lift Coverage — Fits a wide range of Genie S-series telescopic booms and Z-series articulating booms, including XC, TRAX, HF, and J variants across multiple platform heights.
- Structural Integrity Where It Counts — A fastener at this grade and size is typically found in high-load structural joints. Using the correct OEM nut preserves the designed clamping force and joint integrity of those connections.
A TL nut (top-locking or all-metal prevailing torque nut) is a high-strength fastener designed to resist loosening under vibration and dynamic loading without relying on a nylon insert. The locking action is built into the distorted top threads of the nut itself, making it well suited to structural joints on aerial lift equipment that experience repeated movement and stress cycles. When a nut of this type is worn, damaged, or replaced with an incorrect grade or thread pitch, the joint it secures cannot maintain proper clamping force — which can allow critical connections to work loose over time. Using the correct OEM part, verified against your machine's parts manual, keeps the joint performing as Genie designed it.
