FAQs
What does BZP stand for?
BZP stands for Bright Zinc Plating, a common surface treatment that provides a bright, corrosion-resistant finish.
Are these washers suitable for outdoor use?
Yes, the BZP finish is designed to offer good resistance to corrosion, making them suitable for most outdoor applications.
Can I use these washers with bolts other than M8?
No, these washers are specifically sized for M8 bolts. Using them with different bolt sizes is not recommended.
What is the purpose of the 'penny' shape?
The term 'penny washer' or 'mudguard washer' refers to its larger diameter relative to its hole size, which helps distribute load over a wider surface area, preventing damage.
How many washers are in a box?
Each box contains 100 Unifix Mudguard (Penny) Washers.
Can these washers be used with stainless steel bolts?
Yes, they can be used with stainless steel M8 bolts, although the galvanic compatibility should be considered in highly corrosive environments.
What is the outer diameter of the washer?
The outer diameter of these washers is 25mm.
Troubleshooting
Washer does not fit M8 bolt
Verify that the bolt is indeed an M8 size. These washers are precisely manufactured for M8 bolts and may not fit other metric or imperial sizes.
Corrosion appearing on washer
While BZP offers good protection, prolonged exposure to harsh chemicals or extremely corrosive environments can eventually affect the coating. Clean the affected area and ensure the washer is dry. For critical applications, consider stainless steel alternatives.
Bolt feels loose after tightening
Ensure the washer is correctly seated and that the bolt is properly torqued. If the material being fastened is soft, the washer distributes pressure, but the bolt's grip ultimately depends on the mating thread or nut.

Setup, Compatibility & Care
Setup:
These washers are designed for straightforward installation. Simply place them onto an M8 bolt before inserting the bolt through the mudguard and into its receiving hole or nut.
Compatibility:
- Bolt Size: Exclusively designed for M8 bolts. Ensure your bolts are M8 before use.
