The Genie 19934GT is a genuine OEM 3/8 Hard Steel Flat Washer, USS spec, designed for a wide range of Genie boom lifts, articulating booms, telehandlers, and vertical mast lifts. Sourced directly from Genie, this washer meets the exact material and dimensional standards required for the assemblies it supports across multiple machine families. Cross-reference part number 19934GT against your parts manual to confirm fitment before ordering. Compatible models include the S-80, S-80X, S-85, Z-80/60, Z-135/70, ZX-135/70, GTH-636, GTH-644, GTH-842, GTH-844, GTH-1048, GTH-1056, and the GRC-12.
Key Features
- Genuine OEM Steel Grade — Hard steel construction meets Genie's specified hardness and load-bearing requirements for fastened joints on aerial and telehandler equipment.
- USS Standard Sizing — The USS flat washer profile delivers the correct bearing surface for 3/8 fastener assemblies, distributing clamp load evenly without shimming or modification.
- Broad Fitment Coverage — A single part that spans Genie S and Z telescopic and articulating boom lifts, GTH telehandlers, and the GRC-12 Runabout vertical mast lift.
- Protects Mating Surfaces — Correct hardness prevents the washer from deforming under torque, keeping joint preload stable and protecting softer substrate materials from fastener pull-through.
- Structural Joint Integrity — On aerial lifts and telehandlers, properly rated hardware at structural connection points is essential to safe, compliant machine operation; using a correctly specified washer is not optional.
A flat washer serves as a load-distributing interface between a fastener head or nut and the surface it clamps. By spreading the clamping force over a larger area, it prevents the fastener from embedding into or damaging the material beneath it and helps maintain consistent joint preload over time. On heavy equipment like boom lifts and telehandlers, where fastened joints are subject to vibration and dynamic loads, a washer of the wrong hardness or size can compress, deform, or allow fastener loosening — compromising the integrity of critical assemblies. Replacing a worn or missing washer with the correct OEM-specified part restores proper clamping performance and keeps the assembly within the manufacturer's design intent.
