Why Washers Matter

It's easy to overlook a washer, but it plays an important role in joint integrity. A hardened washer under a bolt head distributes the clamping force evenly, preventing the bolt head from embedding into a softer surface and losing preload. A spring washer resists loosening from vibration. A flat washer maintains the correct stack-up height in the assembly.

Using the wrong washer — too soft, wrong size, or missing entirely — can lead to loosening fasteners, fluid leaks at gasket joints, and component misalignment.

When to Replace

• The washer is deformed, crushed, or cracked
• Corrosion or pitting visible
• The washer has taken a permanent set and no longer provides spring force
• The fastener was removed during service — inspect the washer and replace if damaged
