Customer Reviews (4.0 / 5 · 5 reviews)

Elizabeth ★★★★★

Needed 4x3/8 washers for some plastic shelving repair work, and the nylon material really is perfect for avoiding scratches on painted surfaces. The .040" thickness gives just enough lift without being bulky, and a thousand of them means I've got spares for years.

Victoria ★★★★☆

Just what I needed for a small electronics project—these nylon washers are lightweight and don’t scratch the board. The .040" thickness feels sturdy enough for light-duty use.

Richard R. ★★★★☆

These nylon washers are nice and lightweight, which is perfect for protecting surfaces on my small electronics projects. The 1000-count package is great for the price, though I wish they were slightly thicker for heavier-duty applications. They fit the #4 screws exactly as expected.
