Customer Reviews (4.6 / 5 · 5 reviews)

Aurora U. ★★★★★

Perfect for isolating those tiny #4 screws in tight electrical spots—the fibre material really does prevent shorts. I used a handful on a small terminal block project and they held up well under the fastener torque.

Natalie I. ★★★★★

Exactly 0.120" inner diameter, so these fibre washers fit snugly on #4 screws without slipping. Perfect for isolating terminal connections on my small electronics projects where metal washers would cause shorts.

William ★★★★★

The 0.120" inner diameter was a perfect fit for my #4 screw, exactly as specified. These fibre washers provide the electrical insulation I needed for a small terminal board repair. I've used a dozen so far and they hold up well under moderate torque.
