Key Features
- A574 Alloy Steel Construction — Manufactured to the A574 high-strength alloy standard, giving this screw the load-bearing capacity required for structural and mechanical fastening on aerial boom lifts.
- Exact Thread and Size Match — The 5/8-11 thread pitch and 4-inch length are identity specifications; this screw installs directly in place of the original without rework or modification.
- Socket Head Drive — The socket head configuration allows torque to be applied with a hex key in tight or recessed locations where a standard hex-head wrench cannot reach.
- Genuine OEM Part — Sourced directly through Genie's OEM supply chain, ensuring dimensional and material conformity to the original hardware specification.
- Fits Key Z-Series Articulating Booms — Confirmed fitment on the Z-60/34, Z-135/70, Z-51/30J, and Z-30/20, covering a broad range of Genie articulating boom lift platforms.
A socket head cap screw is a high-strength threaded fastener used to clamp or secure structural components, brackets, or mechanical assemblies on the machine. The socket drive recess in the head allows precise torque application using a hex key, making it well suited for confined installation points. When a fastener of this type loosens, stretches, or fails, the joint it secures can shift or lose clamping force — making prompt replacement with the correct OEM part essential to keeping the assembly properly torqued and structurally sound.
