Long-lasting corrosion resistance - with 304 stainless steel

304 stainless steel construction gives inherent corrosion resistance suitable for damp or greasy workshop environments, as stated in the description. User feedback also references a durable 1mm construction that contributes to robustness.

Corrosion-resistant material keeps fixings rust-free and reliable, reducing the need for premature replacement and extra maintenance.

Secure load spreading - with flat penny washer design

Flat, wide profile increases the contact area around an M6 fastener, distributing clamping forces across a larger surface. The outer diameter of 18mm provides a stable seating surface for bolts and screws.

Reduced risk of workpiece damage and fewer loose connections under vibration, making assemblies last longer and perform more reliably.

Ready supply for repairs - with a 30-piece set

Thirty identical M6 washers supply multiple assemblies and spare parts for routine maintenance and DIY projects. The consistent sizing simplifies replacement and stock management in small workshops.

Having a 30-piece pack on hand keeps jobs moving without interruption and cuts down on trips to suppliers.
