Flat washers spread the load of a screw head or nut and protect softer surfaces from being marred as a fastener is tightened, and this category covers nylon flat washers in common SAE sizes. Nylon is light and non-conductive, which makes these washers useful around electronics and finished surfaces where a metal washer might scratch or short.
Numbered Sizes
The range includes #2, #4, #6, #8, and #10 washers, each supplied in packs of six, so you can stock the sizes that match the screws you use most. Matching the washer bore to the screw keeps it centered and spreads the clamping force evenly.
Larger Bore Option
A larger washer measuring 1/4 inch inside diameter by 3/4 inch outside covers wider bearing needs where a numbered size is too small. Keeping a small assortment of washer sizes on the bench saves interrupting a build to hunt for the right one.
See the washers below to match a size to your fasteners.
