This 1-inch flat washer with a 10mm centre hole is a large-diameter galvanised steel washer designed to spread the clamping load of an M10 / 10mm fastener over a wider surface area. The combination of an approximately 25mm outside diameter and 10mm centre hole makes this style particularly useful where a standard M10 washer does not provide enough bearing area.

Why Use a Large-Diameter Washer?

  • Compared with a conventional M10 flat washer, the larger 25mm OD provides more surface area beneath the bolt head or nut. This can be beneficial on slotted brackets, thinner steel sections, trailer roller brackets and adjustable mounting assemblies.
  • Standard M10 washers can be only around 20mm OD, illustrating the additional bearing area provided by the 25mm version.

Suitable Applications

  • Suitable for compatible boat trailer roller brackets, tube adjusters, winch-post brackets, skid supports, yokes, mounting plates and general trailer hardware requiring a 10mm hole with a larger 1-inch bearing surface.
