Need some reliable washers for your next project? This pack from uxcell has you covered. You get 20 pieces of plain, flat washers in the M20 size. That means the inner diameter (the hole) is 20mm (about 0.8 inches), the outer diameter is 36mm (about 1.4 inches), and they're 1.9mm (about 0.08 inches) thick. They're made from 304 stainless steel, which is a great all-purpose grade that's corrosion-resistant and strong, so they're perfect for outdoor use or in damp environments where regular steel would rust. The silver tone is clean and simple. These washers are used to distribute the load under the head of a bolt or nut, protecting surfaces and preventing the fastener from digging in. They're essential for DIY, automotive work, machinery, furniture assembly, you name it. At 20 pieces, you'll have plenty for your current job and some leftovers for the toolbox. Just grab the right size bolt (M20 refers to the bolt thread size) and you're good to go.
