20 Pack 1/2 Inch ID Stainless Steel Lock Washers - 304 Grade Split Washer Assortment

About This Product

This 20-pack of 1/2 inch ID stainless steel lock washers is exactly what every DIYer and mechanic needs in their toolbox! Made from high-quality 304 (18-8) stainless steel that provides excellent strength and corrosion resistance - these washers won't rust like cheaper alternatives. The inside diameter is 0.5 inch with a thickness of 0.125 inch, meeting ASME B18.21.1 measurement standards. The split design with offset ends is what makes lock washers so effective - they bite into the mating material to provide that crucial locking feature when tightened beneath a nut. Perfect for applications where vibration or corrosion could cause loosening over time - think automotive work, machinery, construction, furniture assembly, and pretty much any project using bolts where two pieces need to be drawn together securely. The 304 stainless steel composition means these washers can handle outdoor applications, marine environments, and any situation where moisture might be a concern. No coating or exterior finish means you're getting pure stainless steel performance. The 20-piece pack gives you plenty for multiple projects or to keep as spares in your workshop. Ideal for woodworking, cabinet making, kitchen worktops, tables, cribs, and all kinds of furniture assembly. Whether you're a professional tradesperson or a weekend DIY enthusiast, having quality lock washers on hand makes all the difference in creating secure, long-lasting assemblies that won't come loose over time. Much better than trying to reuse old washers or using inferior quality fasteners that compromise your projects!
