The Genie 1256851GT Hex Head Flange Screw, 1/2-13x3.5 is a genuine OEM fastener built for Genie S and SX telescopic boom lifts, Z and ZX articulating boom lifts, and GTH telehandlers. Sourced directly from Genie, this screw matches the original hardware specification for thread pitch, grade, and finish — ensuring the assembly torques and seats correctly. Cross-reference part number 1256851GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Grade and Finish — Grade 8 construction with a ZAG (zinc-alloy) corrosion-resistant coating matches the original fastener spec at the point of assembly.
- Correct Thread Spec for a Direct Swap — 1/2-13 UNC thread and 3.5-inch length replicate the factory hardware exactly, so the screw seats and threads without reworking the joint.
- Broad Genie Equipment Compatibility — Fits a wide range of Genie S and SX telescopic boom lifts, Z and ZX articulating boom lifts, and GTH series telehandlers, covering multiple variants and configurations.
- Structural Integrity Where It Counts — A correctly spec'd fastener maintains the clamping force the joint was designed for; an incorrect or worn screw can allow movement, loosening, or structural compromise over time.
A hex head flange screw combines a standard hex drive head with an integrated flange that distributes clamping load across a wider bearing surface, reducing the risk of the fastener pulling through or damaging the mating material. The built-in flange also eliminates the need for a separate flat washer in many applications, simplifying reassembly and maintaining joint alignment. Using the correct OEM fastener — matched to grade, thread, length, and coating — is essential wherever torque specifications and joint integrity are critical to safe machine operation.
