Product details:

Waxed Nylon Insert Lock Nuts are treated with wax to act as an on-board anti-seize which saves time and money because an anti-seize solution does not have to be applied to every stainless steel fastener assembly. The anti-seize is already in the nut (via the wax). This time saving property makes Waxed Nylon Insert Lock Nuts ideal for assembly lines, factories, or anyone looking to skip a step and save time.
