Crown Thread Locking Adhesive CR061004-026 – CR61004-026

This thread locking adhesive is manufactured by Crown for use on Crown lift trucks, applied to threaded fasteners to keep them from backing out under the vibration a forklift generates during normal operation. Threadlocker works by curing into a semi-rigid resin inside the threads once the fastener is torqued down, filling the microscopic gaps between the threads so the bolt or nut cannot rotate loose on its own.

On a forklift, this kind of adhesive is typically used on fasteners in high-vibration locations such as mast, chassis, or hydraulic component mountings, where a bolt backing out even partially can lead to a loose assembly or a leak path at a fitting. Because it is a chemical product rather than a mechanical part, its performance depends on proper surface preparation and correct torque at application rather than on wear over time.

At roughly 0.02 pounds, this is packaged in a small container consistent with a threadlocker tube or bottle rather than a bulk industrial size. Ordering against the manufacturer part number ensures the correct locking strength for the fastener application on the Crown truck it is used on.
