Key Features
- Genuine OEM Construction — Hardened zinc-coated steel per DIN6916 HRD ZAB specification, matching the material grade and surface treatment of the original hardware.
- M20 Sizing for Direct Installation — Machined to M20 bore and bearing-surface dimensions, this washer drops straight into existing bolt assemblies without any sizing adjustments.
- Broad Boom Lift Coverage — Fits Genie SX super-boom telescopic lifts, S-series telescopic booms, and Z-62/40 articulating boom lifts, making it a practical stock item for mixed Genie fleets.
- Proper Load Distribution — A correctly rated hardened washer spreads clamp load evenly across the joint face, protecting structural and mechanical interfaces from deformation under high-torque fastening.
- Structural Joint Integrity — On aerial boom lifts, maintaining specified hardware at critical fastener points is essential to the structural performance of the machine — using a correctly graded washer keeps bolted joints within engineered tolerances.
A flat washer serves as a bearing surface between a fastener head or nut and the material being clamped. In heavy equipment applications, hardened washers rated to a standard such as DIN6916 are specified at joints where high clamping forces are required, preventing the fastener from embedding into or damaging the mating surface over time. When a washer is missing, undersized, or of insufficient hardness, bolt preload can be lost as the hardware settles or the surface deforms, leading to loosened joints that may require more extensive inspection and repair to bring back into specification.
