The Genie 74712GT Socket Head Cap Screw, 5/8-11 x 2.75, A574 is a genuine OEM fastener built for Genie GS scissor lifts, TZ trailer-mounted articulating booms, and Z articulating booms. Sourced directly through the OEM supply chain, this screw meets the material grade and dimensional specifications Genie engineering calls for at the factory. It fits a wide range of models including the GS-3390, GS-5390, TZ-34/20, TZ-50, Z-45/25, Z-45/25J Bi-Energy, Z-45/25J IC Power, Z-51/30J, and Z-40/23N, among others — always cross-reference part number 74712GT against your machine's parts manual to confirm it is the correct item for your unit.
Key Features
- A574 Alloy Grade Strength — The A574 designation indicates a high-strength alloy steel socket head cap screw, delivering the tensile performance Genie specifies for structural and mechanical fastening points on these machines.
- Exact Thread and Length Spec — Cut to a 5/8-11 thread pitch and 2.75-inch body length, this screw seats correctly without shimming, re-drilling, or modification to the mating component.
- Broad Genie Fleet Coverage — A single part number covers GS scissor lifts, TZ trailer booms, and multiple Z articulating boom variants, simplifying inventory management across a mixed Genie fleet.
- Genuine OEM Traceability — Supplied as a genuine Genie OEM part, the screw carries the correct material certification and dimensional conformity expected at each fastened joint, reducing the risk of premature loosening or fastener failure.
- Structural Integrity at Every Joint — A fastener at the wrong spec — incorrect grade, thread pitch, or length — can allow movement at critical joints. Installing the correct OEM screw keeps clamping loads within design limits and helps maintain the structural integrity of the assembly it secures.
A socket head cap screw is a high-strength threaded fastener driven by an internal hex (Allen) socket, allowing it to be installed in tight spaces where a hex head wrench cannot reach. On Genie aerial equipment, fasteners like this one secure structural pivot points, platform components, and mechanical assemblies that must remain firmly clamped under repeated load cycles and movement. A fastener that is the wrong grade, stripped, or missing from a joint can allow unwanted play in the assembly it holds together, which — left unaddressed — can accelerate wear on surrounding components or compromise the integrity of the connection. Replacing a worn or damaged screw with the correct OEM part, such as the 74712GT, restores the designed clamping force and keeps the joint performing as Genie intended.
