The Genie T109857GT is a genuine OEM Hex Head Cap Screw, M6-16X10.9, ZN5 built for the GR-20J and GR-26J Runabout vertical mast lifts. As a direct OEM replacement, this fastener matches the original specification for thread pitch, tensile grade, and zinc-flake coating used on the production line. Cross-reference part number T109857GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- OEM-Grade Material and Finish — Manufactured to the M6-16X10.9 strength grade with a ZN5 zinc-flake coating for corrosion resistance, matching the original fastener specification exactly.
- Direct OEM Replacement — Threads, head dimensions, and coating conform to Genie's original design, so this screw installs without modification or reworking of the mating components.
- Confirmed Fitment — Verified for the GR-20J and GR-26J Runabout self-propelled vertical mast lifts; always confirm part number T109857GT against your parts manual for your specific unit.
- Structural Integrity at the Joint — A fastener at the correct grade and torque spec holds mated components securely under the dynamic loads these lifts encounter in daily use; a stripped or incorrect-grade screw can allow unwanted movement at the joint.
- Genuine Genie OEM Part — Supplied as a genuine OEM component, ensuring this part meets the same quality controls applied to every fastener used in original Genie equipment assembly.
A hex head cap screw is a threaded fastener used to clamp two or more components together at a fixed joint. The strength grade — 10.9 in this case — indicates the fastener's tensile and yield strength, which determines how much clamping force it can safely deliver and sustain. The ZN5 zinc-flake coating provides a layer of corrosion protection suited to outdoor and variable-weather operating environments. Using a fastener of the wrong grade or thread specification at a structural joint can result in loosening, fatigue failure, or damage to the mating threads, so replacing a worn or damaged screw with the correct OEM part is the straightforward way to restore the joint to its original condition.
