Round Washers

Metric round flat washers in BZP, HDG, and A4 stainless steel for use with bolts, nuts, and threaded rods from M6 to M24. Flat washers distribute the clamping force of a nut or bolt head over a larger surface area, preventing damage to the material and reducing the risk of the fastener pulling through.

Manufactured to DIN 125, our round washers are available in packs for trade quantities or in smaller quantities for project use. Match your washer finish to your bolt and nut for a consistent, compatible assembly.

Not sure which finish to choose?

We stock fasteners in three finishes to suit every application. BZP is ideal for indoor and sheltered use. HDG gives heavy-duty protection for outdoor, structural, and timber work. A4 Grade 316 Stainless is the right choice for marine, coastal, and chemical environments. Read our guide to pick the right finish for your project.
