The Genie 16977GT is a genuine OEM Hex Head Cap Screw, 1/2-13 x 8.5 built for the Genie IWP Super Series push-around personnel lifts and the TZ-34/20 trailer-mounted articulating boom. As a factory-sourced fastener, this screw meets the exact thread specification, length, and grade called out in the Genie parts manual, ensuring a correct fit without modification. Cross-reference part number 16977GT against your machine's parts diagram before ordering to confirm it is the right item for your application.
Key Features
- Correct Grade and Dimensional Spec — Manufactured to the 1/2-13 thread pitch and 8.5-inch length specified for these machines, so the fastener seats and torques exactly as intended.
- Genuine OEM Sourcing — Supplied directly through the Genie OEM parts chain, matching the material grade and head geometry of the original hardware.
- Confirmed Fitment — Fits the Genie IWP Super Series personnel lifts and the TZ-34/20 trailer-mounted articulating boom.
- Structural Integrity — A fastener of the correct grade and size maintains the clamping load the joint was engineered for; an incorrect or worn substitute can allow movement or loosening under load cycles.
- Safety-Critical Connection — On aerial equipment, structural fasteners are load-bearing components. Using the specified OEM screw supports the integrity of the joint and the machine's overall safety rating.
A hex head cap screw is a fully threaded or partially threaded fastener driven by a wrench on its six-sided head, used to clamp structural members or attach components with a precise, controlled torque. On aerial lifts and trailer-mounted booms, these screws appear in structural joints, pivot points, and mounting assemblies where maintaining the correct clamping force is essential. A fastener that is the wrong length, thread pitch, or grade can back out under vibration, strip the mating threads, or fail to develop the required clamp load — any of which can compromise the integrity of the connection. Replacing a worn or damaged screw with the correct OEM part restores the joint to its original specification.
