Keeping park bench bolts tight is crucial for public safety and longevity. Over time, vibration, weather, and regular use can cause nuts and bolts to loosen. To prevent this, start with the right hardware. Use lock washers, like split washers or internal/external tooth washers, under the nut. These create constant tension and bite into the surfaces, resisting rotation. For a more permanent solution, apply a thread-locking adhesive (like Loctite) to the bolt threads before assembly. This chemical compound hardens to lock the fastener in place. Regular inspection is key. Schedule maintenance checks every few months to tighten any fasteners that have worked loose. For critical joints, consider double-nutting (using two nuts jammed together) or installing nylon-insert lock nuts. By combining mechanical locking devices, chemical adhesives, and consistent upkeep, you can ensure park benches remain sturdy and safe for years of public use.
