💡 How do brass flat washers keep bolted joints tight over time?

They act as a handy metal spacer that takes the abuse off direct thread contact during heavy machinery runs.

- The smooth brass ring reduces friction so bolts hold their tension longer in vibrating equipment

- Wide outer diameters distribute load across larger surface areas to stop wood or thin metal from cracking

- Thick base plating seals out moisture and keeps fasteners corrosion free during long term outdoor use
