As a direct OEM replacement, this screw is manufactured to the same dimensional and material specifications as the original hardware, ensuring a true drop-in fit without modification. Compatible machines include the S-80, S-85, S-100, S-105, S-120, S-125, Z-40/23N, Z-40/23N RJ, Z-80/60, TMZ-34/19, TML-4000, and TML-4000N. Verify part number 59746GT against your machine's parts manual to confirm this is the correct fastener for your application before ordering.
Key Features
- OEM-Grade Material and Dimensional Accuracy — Manufactured to Genie OEM specifications, this screw meets the exact thread pitch, grip length, and head dimensions called out in the original parts manual.
- Correct 5/8-11 x 4.0 Thread and Length Spec — The 5/8-11 coarse thread and 4.0-inch length match the original fastener precisely, so installation goes straight to torque without rework or shimming.
- Broad Equipment Compatibility — Fits Genie S-series telescopic boom lifts, Z-series and TMZ articulating boom lifts, and TML Terex mobile light towers across multiple model variants.
- Structural Integrity Where It Counts — A correctly sized and properly torqued hex head cap screw maintains the clamping force critical to structural joints. A worn, stretched, or incorrect fastener can allow movement in joints that must remain rigid.
- Sourced Direct from Genie OEM Supply — Supplied as a genuine Genie part through authorized distribution, so you receive the same hardware that leaves the factory — not a dimensional approximation.
A hex head cap screw is a fully threaded or partially threaded fastener with a six-sided head designed to be driven by a wrench or socket. On aerial equipment and light towers, these screws are used throughout structural assemblies, pivot points, and mounting brackets where high clamping force and dimensional consistency are essential. When a fastener stretches, corrodes, or is replaced with an incorrect size, joint integrity is compromised — leading to looseness, accelerated wear on mating components, or fastener failure under load. Using the correct OEM screw with the specified thread pitch and length ensures the joint performs as the manufacturer designed it.
