The Genie 1256855GT Hex Head Flange Screw is a genuine OEM fastener built for a wide range of Genie equipment, including S and SX telescopic boom lifts, GS scissor lifts, Z and ZX articulating boom lifts, and select GTH telehandlers. As a direct OEM replacement, this screw is produced to the same dimensional and material standards as the original hardware it replaces. Cross-reference part number 1256855GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- OEM-Grade Hardware — Manufactured to Genie's original dimensional specifications, including the correct thread pitch, shank length, and flange geometry for a secure, properly torqued installation.
- Direct Drop-In Replacement — The hex head flange design seats and clamps exactly as the original, with the integrated flange distributing load without a separate washer.
- Broad Equipment Coverage — Fits Genie S and SX telescopic booms, GS scissor lifts, Z and ZX articulating booms, and select Genie GTH telehandlers across multiple model variants.
- Correct Zinc-Coated Finish — ZAG-finished for corrosion resistance, helping the fastener maintain clamping force and resist surface degradation in outdoor and variable-weather jobsite conditions.
- Fastener Integrity Matters — A fastener that is the wrong size, thread, or grade can back out, strip, or fail to hold the assembly at the correct preload, leading to loose components and unplanned service calls.
A hex head flange screw combines a standard hex head with an integrated flange that acts as a built-in washer, spreading the clamping load over a wider surface area without requiring a separate washer during assembly. This makes installation faster and more consistent, and ensures the joint is held at the correct load across its service life. When a fastener of this type is substituted with an incorrect thread size, length, or finish, the joint may not clamp properly — leading to movement, wear, or component separation over time. Using the correct OEM screw, confirmed by cross-referencing 1256855GT in your Genie parts manual, keeps every assembly seated and torqued as designed.
