The Genie 1256851GT is a genuine OEM Hex Head Flange Screw, 1/2-13x3. As a direct OEM replacement, this screw is manufactured to the same specifications as the original hardware, ensuring consistent clamping performance wherever it is installed. It fits Genie S and SX telescopic booms, Z and ZX articulating booms, and GTH telehandlers — cross-reference part number 1256851GT against your machine's parts manual to confirm it is the correct fastener for your application. Ordering the OEM-spec fastener removes any uncertainty about thread pitch, head geometry, or coating compatibility.

Key Features

  • Exact Thread and Head Specification — The 1/2-13 thread pitch and flange head profile match the original hardware precisely, so the screw seats and torques correctly without modification.
  • Broad Genie Equipment Fitment — Fits S and SX telescopic boom lifts, Z and ZX articulating boom lifts, and GTH series telehandlers, making it a practical stocking fastener for mixed Genie fleets.
  • Genuine OEM Part — Supplied as a genuine Genie OEM component, so traceability, material grade, and dimensional conformity are backed by the manufacturer.

A hex head flange screw combines a standard hex drive head with an integrated flange that distributes clamping load over a wider bearing surface, reducing the risk of fastener pull-through or surface damage in the joined material. The flange also acts as a built-in washer, eliminating a separate loose component and maintaining consistent clamp force. When a fastener of this type is missing, incorrectly graded, or cross-threaded, the joint it secures can loosen under vibration or load, which on aerial equipment can affect structural connections and lead to premature wear of surrounding components. Replacing a worn or damaged fastener with the correct OEM-specification part restores the designed clamping integrity to that joint.
