The Genie 1257803GT Hex Head Flange Screw, 5/16-18x2, 8, ZAG is a genuine OEM fastener built for Genie GTH series telehandlers, including the GTH-636, GTH-844, and GTH-1056. Sourced directly from Genie, this screw matches the exact thread pitch, shank length, grade, and finish specified for the application — no guesswork, no adaptation required. Cross-reference part number 1257803GT against your machine's parts manual to confirm it is the correct fastener for your unit before ordering.
Key Features
- Exact Thread and Dimension Match — 5/16-18 thread pitch and 2-inch shank length conform precisely to the fastener specification, so it seats and clamps correctly without rework.
- Integrated Flange Bearing Surface — The flanged head distributes clamping load evenly across the mating surface, reducing the risk of fastener loosening under vibration and load cycles common in telehandler operation.
- Confirmed GTH Telehandler Fitment — Fits the GTH-636, GTH-844, and GTH-1056, covering a broad range of Genie telescopic handler configurations from a single part number.
- Direct OEM Replacement — As a genuine Genie part, this screw replaces the original fastener on a like-for-like basis, maintaining the integrity of the assembly it secures.
A hex head flange screw combines a standard hex-drive head with an integral flanged washer to spread the clamping load over a wider area. This design helps maintain joint preload in assemblies subject to vibration — a routine condition for telehandlers working on rough or uneven terrain. When a fastener of this type is missing, damaged, or substituted with an incorrect grade or thread, the joint it secures can work loose over time, compromising the structural or mechanical integrity of that assembly. Using the correct OEM specification fastener keeps the joint performing as Genie designed it.
