This penny washer is designed for use with M12 bolts or threaded rods, featuring a flat steel construction with a bright zinc plated finish. The 40mm outside diameter provides a larger bearing surface, which helps distribute loads when fixing into softer materials or oversized holes.
Commonly used in timber work, metal fabrication, and general construction, it is suitable for situations where a standard washer may not offer sufficient support. Its robust design makes it useful for securing panels, brackets, or fixings on site with added stability.
