For all you DIYers and tradespeople, these TIMco square plate washers are one of those basic supplies you'll be glad to have in your toolkit. Each washer measures 8x40x5mm, giving you a nice large surface area to spread the load of your fastenings and prevent damage to whatever material you're working with. The zinc plating with 3-5 micron thickness provides solid corrosion resistance, and the passivation process helps them last longer without rusting. They come in a handy box of 100, so you've got plenty for multiple projects without constantly reordering. Square washers are particularly useful when you need that extra stability or when working with larger bolt heads - they distribute pressure way better than standard round washers. Whether you're building furniture, working on automotive projects, or doing general repairs around the house or workshop, having these on hand just makes things easier. The quality is exactly what you'd expect from TIMco - consistent sizing, clean edges, and reliable performance. They're one of those simple components that you don't think about until you need them, and then you're super grateful you have a box ready to go.
