Product Information

Full details

The Unifix Mudguard (Penny) Washers are designed for cyclists and DIY mechanics who require a secure, reliable mounting solution for bicycle mudguards. These washers offer excellent load distribution for M5 bolts, ensuring that hardware remains tight and stable during rides; however, users must ensure they match the M5 specification correctly, as they are not compatible with larger bolt sizes without the appropriate variant.

Extended Product Information

FAQs

What size bolt do these work with?

These specific washers are engineered for M5 bolts.

What is the outer diameter of the washer?

The outer diameter is 25mm.

Can I use these for non-bicycle applications?

Yes, they can be used for any project requiring a penny washer with an M5 internal diameter.

Are these washers stainless steel?

They are constructed for durability in professional and DIY applications, designed to handle standard cycling conditions.

How thick are these washers?

These washers have a thickness of 1.5mm.

Troubleshooting

Washer seems too small for the bolt

Check your bolt diameter; this washer is designed specifically for M5. If you have an M6 or M8 bolt, you will need the corresponding variant.

Mudguard still wobbles after tightening

Ensure the washer is pressed firmly against the mudguard bracket and check if the mounting hole in the frame or mudguard has enlarged due to wear.

Pros and Cons

Pros

  • High-quality, reliable hold for mudguards
  • Large 25mm diameter prevents material pull-through
  • Easy to install for DIY enthusiasts
  • Durable finish suitable for outdoor conditions

Cons

  • Specific to M5 bolts, not universal
  • Silver finish may show dirt/grime more than darker colors
  • Not intended for heavy structural load-bearing

Setup, Compatibility & Care

To install, simply slide the washer onto your M5 bolt before inserting it through the mudguard mounting bracket. Ensure the surface of the mudguard is clean and flat to allow the washer to sit flush. These washers are compatible with standard M5 bicycle hardware. For maintenance, periodically check that the bolt tightness remains consistent. If you ride in wet or corrosive conditions, a light coating of bicycle-grade grease on the threads during installation can prevent the bolt from seizing over time.
