The Genie 121688GT is a genuine OEM Hex Head Cap Flange Screw, M14 x 35, built for Genie S-series telescopic boom lifts and Z-series articulating boom lifts. As a direct OEM replacement, this screw is manufactured to the exact thread pitch, shank length, and flange diameter specified for these machines, ensuring a consistent, proper installation. It fits a range of boom lift variants including the S-80, S-80 XC, S-80 HF, S-85, S-85 XC, S-85 HF, and Z-80/60. Cross-reference part number 121688GT against your machine's parts manual to confirm this is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's exact M14 x 35 thread and flange specifications, so the fastener seats and torques correctly without modification.
- Integrated Flange Design — The built-in flange distributes clamping load across a wider bearing surface, reducing the need for a separate washer and maintaining consistent joint integrity.
- Broad Boom Lift Compatibility — Fits multiple variants across the S-80 and S-85 telescopic boom families, as well as the Z-80/60 articulating boom, covering standard, XC, and HF configurations.
- Structural Fastener Reliability — A properly installed fastener maintains the integrity of the joints and assemblies it secures; a stripped, corroded, or incorrect replacement screw can compromise structural connections and lead to costly downtime.
- Aerial Lift Safety Compliance — On boom lifts operating at significant working heights, maintaining every fastener to OEM specification is a direct factor in platform and structural safety. Using the correct Genie OEM part supports proper torque retention and joint integrity.
A hex head cap flange screw combines a standard hex head cap screw with an integral flanged bearing surface beneath the head. This flange spreads the clamping force over a larger area than a plain hex cap screw, helping to prevent fastener loosening under vibration and load cycling — conditions common in mobile boom lift operation. When a fastener in this role is the wrong size, over-torqued, or has degraded threads, it can fail to hold the joint at the required clamp load, potentially allowing connected components to shift or work loose during machine operation.
