The Genie 1251983GT Hex Flange Screw is a genuine OEM fastener designed for a wide range of Genie telescopic and articulating boom lifts, scissor lifts, and telehandlers. Manufactured to DIN6921 specification in Grade 10.9 with a ZAB finish, this screw delivers the dimensional accuracy and clamping strength the original design requires. Genuine OEM sourcing means this part matches the thread pitch, head geometry, and material grade called out in Genie's engineering documentation. Cross-reference part number 1251983GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Grade 10.9 High-Strength Construction — Built to DIN6921 standard at Grade 10.9, delivering the tensile strength and hardness the original Genie assembly demands without substitution.
- Integrated Flange Head — The hex flange head distributes clamping load across a wider bearing surface, reducing the risk of fastener loosening under vibration and load cycling common on aerial equipment.
- ZAB Finish for Corrosion Resistance — The zinc-aluminum-based ZAB coating provides corrosion protection suited to the outdoor and variable-weather environments where Genie equipment operates.
- Direct OEM Replacement — As a genuine Genie part, this screw installs directly in place of the original with no reworking of mating components or thread chasing required.
- Broad Compatibility Across Genie Families — Fits Genie S and SX telescopic booms, Z and ZX articulating booms, GS scissor lifts, and GTH telehandlers, covering a wide range of Genie equipment in a single part number.
- Fastener Integrity Supports Structural Reliability — A fastener torqued to spec holds critical assemblies in correct alignment. A stripped, corroded, or under-strength screw can allow components to shift, making prompt replacement with the correct grade part essential.
A hex flange screw combines a standard hex-drive head with an integral flanged washer, allowing it to clamp two or more components together while spreading the load over a larger contact area than a plain bolt. On aerial lifts and telehandlers, fasteners like this one secure structural, mechanical, and panel assemblies that must remain tight through repeated cycles of movement, vibration, and changing loads. When a screw of this type fails — through corrosion, fatigue, or replacement with an incorrect grade — the joint it holds can work loose, leading to misalignment or accelerated wear of the surrounding components. Using the correct OEM-specified part, with the right thread pitch, grade, and finish, preserves the integrity of the joint and the assembly it anchors.
