The Genie 139140GT is a genuine OEM Stud, 3/4-16 UNF x 2-1/2 LG built for Genie S-series telescopic boom lifts and Z-series articulating boom lifts, including the S-60, S-65, S-65 XC, and Z-62/40. As a genuine OEM part, this stud is manufactured to the exact thread specification and length called out in the Genie parts manual, ensuring correct engagement and clamping load on the first installation. Cross-reference part number 139140GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Thread Conformity — Manufactured to the exact 3/4-16 UNF thread form and 2-1/2 inch length specified by Genie, delivering full thread engagement and correct torque values without rework.
- Direct OEM Replacement — Drops in as a direct replacement for the original stud; no chasing, re-tapping, or adaptation required when the mating threads are in serviceable condition.
- Broad Boom Lift Fitment — Fits the S-60, S-65, S-65 XC, and Z-62/40, covering both telescopic and articulating boom lift platforms in the Genie lineup.
- Structural Fastening Integrity — A correctly sized stud maintains the clamping force that holds structural and mechanical joints in place; an undersized, stripped, or incorrect fastener compromises the integrity of the joint and can lead to component movement or failure.
- Operational Safety Relevance — On aerial boom lifts, fastener integrity at structural joints is directly tied to safe operation at height; replacing a damaged or missing stud with the correct OEM part restores the connection to its designed specification.
A stud is a headless threaded fastener that engages a tapped bore or is secured with a nut on each end, creating a fixed threaded post that allows a mating component to be removed and reinstalled without disturbing the base thread. The 3/4-16 UNF thread form is a fine-pitch designation that provides higher thread engagement per inch compared to coarse-pitch threads, making it well suited to joints where vibration resistance and precise clamping are important. When a stud is damaged, stretched, or missing, the joint it anchors cannot be properly torqued, which affects the structural connection and must be corrected before the machine is returned to service.
