4711 | غسالة كتف كيستون | قطر داخلي 1/4 بوصة | ليف أسود (50/عبوة)

The shoulder on these fibre washers is just the right thickness to keep my standoffs from shorting against the chassis. Installed a batch of 50 on a new control board and every one seated cleanly without splitting. Exactly what I needed for clean electrical isolation on those through-hole mounts.

Perfect fit for isolating those board standoffs I was replacing, and the black fibre material feels sturdy enough for repeated assembly. The 1/4" inner diameter held snug on the screw threads without any wobble.

Exactly what I needed for isolating a couple of power transistor mounting holes on a PCB. The 1/4" ID fit perfectly over the screw shaft, and the 0.093" thickness provides just enough standoff. Good to have a 50-pack on hand for future builds.
