Washers are thin, flat discs placed between a fastener (bolt or nut) and the surface being secured, distributing load and preventing damage to surfaces. Ideal for furniture assembly, machinery, automotive components, structural joinery, and shelving, they reduce loosening under vibration and improve the overall stability of bolted assemblies. Browse our range of washers, including flat and square plate designs, in zinc-plated and stainless steel finishes. With variations in inner diameter, outer diameter, and thickness, they provide differences in load distribution, corrosion resistance, and suitability for light- to general-duty fastening applications. Meeting the needs of DIYers, builders, carpenters, joiners, engineers, and trade contractors, our washers feature precise dimensions and smooth surfaces to help prevent scratching.
