Bulk Pack: Incredible value bag of 1000 caps for large-scale inventory maintenance.
Safety First: Protects workers and pedestrians from sharp, exposed scaffold bolt threads.
High Visibility: Bright yellow finish highlights protruding bolts to prevent snags and injuries.
Corrosion Protection: Keeps threads clean and free from mortar, grit, and rust.
Universal Fit: Flexible design fits all standard scaffolding bolt threads.
Our Yellow Thread Caps are a simple, cost-effective solution for improving site safety and extending the life of your scaffolding fittings. Designed to push-fit over the exposed ends of scaffold bolts, these caps provide a protective barrier that benefits both your equipment and your crew.
Exposed threads on scaffold couplers can be incredibly sharp, often causing cuts to hands or snagging expensive PPE and high-visibility clothing. By fitting these bright yellow caps, you create a smooth, blunt surface while simultaneously making the protruding bolt much more visible to anyone working on or near the scaffold.
One of the biggest causes of seized fittings is “thread contamination.” When mortar, cement, or grit gets into the threads during a project, it makes striking the scaffold significantly harder. These caps seal the thread, ensuring that when it’s time to dismantle, the nuts spin off freely.
Professional Appearance: Using thread caps gives your scaffold a tidy, finished look that reflects well on your company’s safety standards.
Durable Plastic: Manufactured from weather-resistant polyethylene that won’t crack or fade easily in the sun.
Fast Application: Easy push-on design requires no tools and stays securely in place until removed.
Reusable: Can be easily popped off and returned to the yard for use on the next project.
