The Genie 51131GT is a genuine OEM Hex Head Cap Screw, 5/8-11 X 2.5, built for a wide range of Genie equipment including S series telescopic boom lifts, Z and ZX series articulating boom lifts, GS series scissor lifts, and AL, RL, and TML light towers. As a direct OEM replacement, this screw is manufactured to the exact thread pitch, head dimensions, and material grade specified for the applications it serves. Cross-reference part number 51131GT against your machine's parts manual to confirm it is the correct fastener for your unit before ordering.
Key Features
- OEM Thread and Dimensional Conformity — Manufactured to the exact 5/8-11 thread specification and 2.5-inch length called out in Genie parts documentation, ensuring correct torque engagement and clamp load.
- Direct OEM Replacement — Slots directly into the existing fastener position with no rework, matching the head size and grip length of the original hardware.
- Broad Equipment Coverage — A single part number serves Genie S series telescopic booms, Z and ZX series articulating booms, GS series scissor lifts, and AL, RL, and TML light towers.
- Structural Integrity You Can Count On — A correctly spec'd fastener holds critical assemblies at the designed clamping force; an undersized or incorrect substitute risks joint loosening under vibration and load cycles.
- Genuine Genie OEM Part — Sourced directly through the Genie OEM supply chain, so the grade, finish, and dimensions match what left the factory originally.
A hex head cap screw is a threaded fastener used to clamp or secure structural and mechanical assemblies on the machine. The 5/8-11 designation refers to the thread diameter and thread pitch, while the 2.5-inch length determines how deeply the fastener engages the mating material. When a fastener stretches, corrodes, or is lost during service, replacing it with the correct OEM specification is essential — an incorrect length or thread pitch can result in insufficient clamping, thread damage, or joint failure under working loads. Keeping the correct replacement on hand helps ensure structural assemblies are returned to their original fastened condition after any service work.
