Nylon Flat Washers
Nylon flat washers are light, non-conductive and corrosion-free, used for insulation, surface protection and sealing light-duty fixings. We supply nylon washers across a wide range of metric sizes.
Also known as: plastic washers, insulating washers, polyamide washers.

Materials & strength
Insulating
Non-conductive and non-magnetic, isolating fixings electrically and preventing galvanic corrosion between dissimilar metals.
Surface protection
Softer than metal washers, protecting paint and polished finishes from marking during tightening.
What are nylon washers used for?
Nylon washers insulate electrically, prevent metal-to-metal contact and galvanic corrosion, protect painted or polished surfaces, and act as a light seal or anti-rattle element in low-load fixings.
What temperature and load can nylon washers take?
Nylon is a light-duty material: service temperature and clamping load are both well below metal washers, so it suits low-stress fixings rather than structural joints. Send us your requirement and we can advise a suitable washer.
