Description
Overview:
This Square Plate Washer is a heavy-duty, self colour steel washer designed for use with M12 bolts, set screws, threaded rod and anchor fixings. The square plate measures 1.1/2" (38 mm) across with a 3 mm thickness, giving a broad bearing surface to spread clamping loads and protect softer or uneven materials from damage. The round centre hole suits M12 fasteners for straightforward, secure assembly. Commonly used in construction, fencing, machinery mounting, formwork and plant repairs, it helps prevent pull-through and improves joint stability on timber, steel and masonry fixings. Plain (self colour) finish is ideal for users who wish to paint, galvanise or leave as-is. Sold individually for flexible purchasing. Manufacturer Part Number: 903 1184.
