The Genie 1258418GT is a genuine OEM Hi Collar Lock Washer, 1/2 designed for the GTH-1056 telehandler. Sourced directly from Genie, this washer is built to the same specification as the original hardware installed at the factory, ensuring correct torque retention and fastener integrity. Cross-reference part number 1258418GT against your GTH-1056 parts manual to confirm application before ordering.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Genie's material and dimensional standards for zinc-alloy plated (ZAG) lock washers, delivering consistent clamping force and corrosion resistance in telehandler service conditions.
- High-Collar Profile for Positive Locking — The raised collar design bites into mating surfaces under load, resisting fastener loosening caused by vibration during telescoping and travel cycles.
- Direct Replacement for GTH-1056 — This washer installs in place of the original hardware with no modification, maintaining the correct fastener stack-up on the GTH-1056 telehandler.
- Protects Fastener Joint Integrity — A worn or missing lock washer allows bolted connections to back off over time, leading to loose assemblies, accelerated wear on mating components, and potential structural movement where tight joints are critical.
- Operational Safety on Lifting Equipment — On a telehandler, secure fastener joints throughout the boom, carriage, and frame are essential to safe load handling. Using the correct OEM washer helps maintain the integrity of those connections.
A hi collar lock washer is a hardened fastening component placed under a nut or bolt head to prevent loosening under vibration and dynamic loading. The raised collar increases the washer's contact height against the fastener face, improving grip compared to a standard flat or split lock washer. On a machine like the GTH-1056 telehandler — which experiences constant extension, retraction, and load-shifting forces — maintaining tight, secure bolted joints is critical. When a lock washer is missing, corroded, or deformed, fasteners can gradually back off, causing play in assemblies that depend on clamped connections to function safely and accurately.
