FAQs

Can I use these washers with M10 bolts?

No, these are specifically sized for M12 bolts. Using them on smaller bolts will result in an insecure fit.

Are these suitable for marine environments?

The stainless steel construction offers high corrosion resistance, making them generally suitable for outdoor and damp conditions.

How many washers are included in the box?

The box contains 200 individual washers.

What is the primary benefit of a 'penny' washer?

The wide surface area distributes pressure across a larger space, protecting thin or soft materials from bolt pull-through.

Will these rust over time?

They are made of high-quality stainless steel, which is highly resistant to rust under normal operating conditions.

Troubleshooting

Washer does not fit over the bolt

Verify that your bolt is indeed an M12 size; the washer has a specific inner diameter meant only for M12 hardware.

Washer is touching edges of surrounding components

The 'penny' style has a wide diameter. Ensure your mounting site has enough flat clearance to accommodate the washer's outer circumference.

Pros and Cons

Pros

  • High-quality stainless steel construction for long-term durability
  • Excellent resistance to oxidation and environmental corrosion
  • Large surface area prevents damage to the mounting material
  • Bulk pack of 200 is cost-effective for frequent users

Cons

  • Strictly limited to M12 bolt specifications
  • Not suitable for heavy-duty structural load-bearing beyond standard fastening
  • Large outer diameter may not fit in recessed mounting holes

Setup, Compatibility & Care

To install, ensure your bolt is an M12 gauge. Simply slide the washer onto the bolt shank before passing the bolt through the mounting hole. When tightening, ensure the washer sits flat against the surface to maximize the pressure distribution. While stainless steel is naturally resistant to rust, avoid contact with incompatible metals in highly acidic or saline environments to prevent galvanic corrosion. No specialized maintenance is required; simply wipe clean if exposed to road grime or dirt to keep them functioning optimally.
