Key Features
- Correct Thread and Length — 5/8-11 thread pitch and 4.0-inch length match the OEM specification exactly, ensuring proper torque and clamping load without modification.
- Genuine Genie OEM Part — Supplied directly by Genie, this fastener meets the dimensional and material standards of the original hardware it replaces.
- Broad Fitment Across Genie Families — Fits GTH-series telehandlers and Z and TZ articulating boom lifts, covering a wide range of Genie equipment in a single part number.
- Structural Integrity Where It Counts — A fastener used at this grade and size typically secures major structural connections. Using the correct grade replacement prevents joint movement, fatigue, and potential fastener failure under load.
A hex head cap screw is a high-strength threaded fastener used to clamp two or more components together at a defined torque. The 5/8-11 x 4.0 specification defines the thread diameter, thread pitch, and grip length — all three must match the original fastener precisely. Using an incorrect grade or length can result in under-clamped joints, fastener failure, or damage to threaded bores, any of which can compromise the integrity of the assembly it secures.
