The Unifix Mudguard (Penny) Washers in M8 are ideal for automotive mechanics, DIY enthusiasts, and trade professionals seeking a reliable solution to distribute load across a wider surface area. These high-quality steel washers feature a bright zinc-plated finish, offering excellent corrosion resistance for long-term durability in various environmental conditions, though they are specifically sized for M8 bolts and may not suit heavy-duty structural applications requiring hardened steel.

This indicates an inner diameter of 8mm for M8 bolts, an outer diameter of 25mm, and a thickness of 1.5mm.
No, these are steel washers with a bright zinc-plated finish for corrosion resistance.
Yes, they are excellent for wood projects as the wide diameter prevents the fastener from pulling through soft timber.
This specific pack contains 500 washers.
The zinc plating provides significant resistance to rust, but they are not rust-proof for permanent outdoor or marine exposure.
Loosen the bolt slightly, align the washer carefully, and retighten gradually to ensure even pressure distribution.
This is zinc oxide. Wipe it off with a dry cloth and ensure storage is kept in a low-humidity environment.
Check if the torque specification is too high for the fastener or if the surface being clamped is uneven.
To ensure proper performance, ensure the surface being fastened is clean and free of debris. Slide the washer onto your M8 bolt before threading it into the nut or tapped hole. When tightening, apply torque evenly to ensure the washer sits flat against the surface to maximize load distribution. While these washers are corrosion-resistant, they should be stored in a dry, cool place to prevent 'white rust'—the oxidation of the zinc layer—from forming inside the box. Avoid using these washers with bolts larger than M8, as the inner diameter will not fit, and do not use them on stainless steel bolts if galvanic corrosion is a concern in your specific application.
