Plastic Washers
These plastic washers are good electrical insulators.
Polycarbonate washers are more rigid than most plastic washers for high impact resistance. They have good moisture resistance and withstand oil, greases, and detergents.

Snap-In Fabric Grommets
No setting tools needed—snap the two parts together in a hole you've already cut to strengthen the hole and eliminate fraying. Use these grommets in tarps, covers, curtains, and other material. Grommet trade size refers to the grommet’s hole size once set. Made of plastic, these grommets are chemical resistant and won't dry out and become brittle when exposed to UV rays. They can be used outdoors. Cutting punches are sold separately.
