The Genie 1273411GT Hex Head Flange Screw, 3/4-10X3.00, 8, ZAG is a genuine OEM fastener built for Genie S-series telescopic boom lifts and GS-series scissor lifts. Sourced directly from Genie, this screw matches the original thread specification, grade rating, and zinc-aluminum flake coating called out in the factory parts manual. It is confirmed to fit the S-40, S-45, GS-3384, GS-3390, GS-4390, and GS-5390. When you need an exact replacement, cross-reference part number 1273411GT against your machine's parts manual to confirm it is the correct item for your application.
Key Features
- Grade 8 OEM Specification — Supplied at Grade 8 strength with the correct 3/4-10 thread form and 3.00-inch length, matching the original fastener specification precisely.
- ZAG Finish for Corrosion Resistance — Zinc-aluminum flake (ZAG) coating provides a durable protective layer suited to the demanding outdoor environments these machines operate in.
- Direct OEM Replacement — Genuine Genie hardware that installs in the same position as the original, with no rework to mating threads or mounting points.
- Broad GS and S-Series Fitment — Fits the S-40, S-45, GS-3384, GS-3390, GS-4390, and GS-5390, covering both telescopic boom lifts and large-platform scissor lifts in a single part number.
- Structural Integrity You Can Count On — A fastener that is the wrong grade, thread pitch, or length can work loose or fail under load; using the correct OEM screw keeps the joint torqued to spec and the machine structurally sound.
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 chance of the fastener pulling through or damaging the material it bears against. The flange also acts as a built-in washer, which simplifies assembly and ensures consistent clamping force at the joint. When a fastener of this type is worn, stripped, or substituted with an incorrect grade or thread, the joint it secures can lose clamping force, leading to movement, wear, or structural compromise in the assembled connection. Replacing it with the correct Genie OEM part restores the joint to its original specification.
