Product description
Penny (repair) washers, zinc-plated, M10 – box of 500. The large-diameter washer that lets an M10 bolt clamp against timber or thin material without pulling through.
M10 is a common heavier-duty size – joist bolts, brackets, fixing thicker timber sections – and that's exactly where a plain washer isn't enough. The penny washer's wide face spreads the clamping load, so the bolt head or nut bears on a big area instead of sinking into the timber or tearing through sheet.
- Thread size: M10
- Finish: bright zinc plated (BZP) – for interior/dry use
- Pack: box of 500
Fit one under the head and one under the nut for a bolt through timber, and match it with an M10 bolt and nut. Outdoors or in damp conditions, choose galvanised or stainless – zinc plating suits dry, interior fixings.
