Description & Specs

The Hobson Engineering M12 Zinc Plated Round Washer is a zinc-plated mild steel washer that distributes the load of a bolted joint and can also act as a spacer. The 28mm round plate spreads clamping force under M12 nuts and bolt heads.

  • Suit bolt size: M12
  • Size: 28 x 2.5mm
  • Shape: Round

Satisfied customer

Had been looking at the Hobson Engineering for a couple of months. Hobson build quality is obvious as soon as you open the box — feels solid and well finished. Easy to set up and works exactly as described. Delivery to Perth in only 3 days which is impressive. Will be buying more from SuperSaver AU for sure.

Absolutely love it!

Had the Hobson Engineering on my wishlist for a few weeks and finally pulled the trigger. Arrived in 2 days which was a nice surprise. Build quality is solid and exactly what the photos showed. My partner uses it every day now and has already asked me to grab another one as a gift.

Best buy of the year

Ordered Thursday and had it by Saturday. Packaging was really good — nothing moved around. Works exactly as expected and the price was well below what I saw in stores.
