The Genie 121420GT is a genuine OEM Hex Head Flange Screw, 1/4-20 x 1.00 built for Genie telescopic and articulating boom lifts and GTH telehandlers, including the S-80, S-80X, S-85, S-85 XC, Z-80/60, and GTH-1056. As a factory-sourced fastener, this screw matches the original thread pitch, shank length, and flange geometry specified for these machines. Cross-reference part number 121420GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's exact 1/4-20 thread specification and 1.00-inch shank length, ensuring the flange seats flush and threads engage correctly every time.
- 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 clamp force on the joint.
- Direct OEM Replacement — This screw installs directly in place of the original without modification, keeping assembly procedures and torque specifications intact.
- Broad Fitment Across Genie Boom and Telehandler Lines — Confirmed for the S-80, S-80X, S-85, S-85 XC, Z-80/60, and GTH-1056, making it a practical stocking fastener for mixed Genie fleets.
- Fastener Integrity — A stripped, corroded, or incorrect-length screw can allow joints to loosen under vibration and load; replacing with the correct OEM part restores secure assembly and structural connection.
A hex head flange screw combines a standard hex-drive head with an integral washer-like flange at its base. The flange spreads the clamping force over a larger area than a plain screw head, helping to secure panels, brackets, and structural members even in high-vibration environments typical of aerial lifts and telehandlers. When a fastener of this type is missing, stripped, or substituted with an incorrect size, the joint it secures can work loose during operation — potentially allowing movement in components that are meant to remain fixed. Replacing a worn or damaged screw with the correct Genie 121420GT restores the intended connection and keeps the assembly holding to specification.
