The Genie 67722GT is a genuine OEM Flat Washer, M12 Hardened designed for Genie TML light towers and TZ and TMZ series trailer-mounted articulating booms. As a factory-sourced component, this washer is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring correct load distribution and clamping performance at every fastened joint. Cross-reference part number 67722GT against your parts manual to confirm the correct application before ordering. This part fits the TML-4000, TML-4000N, TZ-34/20, TZ-50/30, TZ-50, TMZ-34/19, and TMZ-50/30.
Key Features
- Hardened Steel Construction — The M12 hardening specification means this washer resists deformation under high clamping loads, protecting fastener and mating surface integrity over repeated service cycles.
- Genuine OEM Sourcing — Produced to Genie's original material and dimensional standards, this washer delivers the exact bearing surface area and thickness the assembly was engineered around.
- Direct Drop-In Replacement — Sized and finished to match the original hardware, this part seats correctly on M12 fastener assemblies without rework or shimming.
- Broad Coverage Across TML, TZ, and TMZ Units — Fits the TML-4000 and TML-4000N light towers and the TZ-34/20, TZ-50, TZ-50/30, TMZ-34/19, and TMZ-50/30 trailer-mounted booms in a single part number.
- Structural Joint Integrity — A worn or undersized washer allows fastener heads to pull through or pivot, loosening critical structural and mechanical connections. Using the correct hardened washer maintains proper preload across the joint.
- Safety-Relevant Fastener Hardware — On trailer-mounted booms and light towers, fastener assemblies secure structural, hitch, and outrigger components. Using the specified hardened washer supports the clamping performance those connections depend on.
A flat washer distributes the clamping load of a bolt or nut across a wider surface area, preventing the fastener head from embedding into or damaging the material it secures. The hardened designation indicates the washer has been heat-treated to achieve a higher surface hardness, making it suitable for high-load or high-vibration joints where a standard washer would deform or wear through. When a hardened washer is missing, substituted with an unhardened equivalent, or worn thin, clamping force is uneven and the fastener can loosen under load — a condition that is especially critical on the structural, tow, and outrigger connections common to trailer-mounted equipment like the TZ and TMZ boom series and the TML light tower range.
