FAQs

What is the inner diameter of these washers?

These DIN 125A M12 washers have an inner diameter of 13.0mm.

Are these suitable for outdoor use?

Yes, their brass construction provides excellent natural resistance to rust and corrosion in most outdoor environments.

How many washers are included in the box?

Each box contains 200 pieces.

Can I use these with M10 bolts?

No, these are specifically designed for M12 bolts. Using them on M10 hardware will result in an insecure connection.

Are these magnetic?

No, because they are made from brass, they are non-magnetic.

Do I need special tools to install these?

No, these work with standard manual or power-assisted tools used for tightening bolts.

Troubleshooting

Washer sits loosely on the bolt

Verify that your bolt is indeed an M12 size; if the bolt is smaller, the washer will not provide proper load distribution.

Washer appears deformed after tightening

Check if you have exceeded the recommended torque for the assembly, as excessive force can deform brass components.

Washer is difficult to slide onto the bolt

Check the bolt threads for burrs or debris that may be obstructing the washer's inner diameter.

Pros and Cons

Pros

  • High-quality brass material offers superior longevity
  • Excellent resistance to corrosion compared to standard steel washers
  • Standard DIN 125A dimensions ensure universal compatibility with M12 bolts
  • Bulk box of 200 reduces the need for frequent replenishment
  • Provides a clean, professional finish for aesthetic and functional projects

Cons

  • Specifically sized for M12 bolts; not suitable for other thread diameters
  • Brass is softer than stainless steel, which may limit use in high-torque heavy-duty industrial applications
  • Gold finish may tarnish over long periods depending on environmental exposure

Setup, Compatibility & Care

To achieve the best results, ensure that the surface is clean before placing the washer. These components are fully compatible with any standard M12 threaded bolt or screw. When installing, simply slide the washer onto the bolt shank until it meets the surface of the material, then tighten the nut to the required torque specification. Maintenance is minimal; however, if used outdoors, an occasional wipe with a clean cloth can prevent dust accumulation. If the finish dulls over time, a mild brass polish can be used to restore the original luster.
