Description & Specs

The Hobson Engineering M16 50 x 50 x 5mm Square Washer is a hot dip galvanised mild steel washer that spreads the load of a bolted joint over a larger area. Its 50 x 50mm square plate increases the bearing surface under M16 nuts and bolt heads.

  • Suit bolt size: M16
  • Size: 50 x 50 x 5mm
  • Shape: Square
  • Material: Mild steel
  • Finish: Hot dip galvanised

Place it under the nut or bolt head to distribute clamping force, reduce scouring of the mating surface and prevent local crushing of softer materials. The square shape gives a wide bearing footprint, and the hot dip galvanised finish adds corrosion resistance for exposed and outdoor fixings.

Brilliant Aussie deal

Been buying Hobson gear for years and this is one of their better ones. The Hobson Engineering quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.

Worth every cent

Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.
