description

This genuine size‑20 flat washer is stamped from high‑quality steel with flat, uniform surfaces. Heat treatment and anti‑rust surface treatment deliver stable bearing capacity. During tightening, the washer spreads clamping pressure evenly over the workpiece to avoid indentation and compensates for minor unevenness on mating surfaces. It relieves stress concentration under long‑term vibration on pavers. Deformation, cracking, heavy rust or crushing leads to uneven pressure distribution, loose connections and abnormal noise. Replace damaged washers during overhaul.

FAQ

Q: Can a slightly deformed washer be reused?
A: Reuse is not recommended. Warping or indentation causes uneven pressure and loose connections. Replace it directly at heavy‑load positions.

Q: What is the difference between a flat washer and a lock washer?
A: A flat washer spreads pressure and protects surfaces, while a lock washer relies on elastic bite for anti‑loosening. They are often used together under heavy load.

Q: What is the correct assembly order?
A: Standard order: bolt through workpiece → flat washer → nut. If a spring lock washer is added, place the flat washer against the workpiece and the lock washer between flat washer and nut.
