7/8"-9 Nylon Insert Lock Nut - Grade 8 Zinc/Yellow

(Priced per each / Pkg Qty = 25 per/box)

Nylon insert lock nuts are hex nuts that have a captive nylon washer mounted in their top to create a prevailing torque type lock nut. The undersized washer forms a compression grip that binds on the threads of the mating fastener to resist loosening. Due to limitations of the non-metallic insert, the nuts cannot be used at elevated temperatures or with certain chemicals but the nylon washer does provide a gas and moisture seal. Because the washer largely returns to its original form, nylon insert lock nuts may be reused a limited number of times. Lock washers are not used with prevailing torque lock nuts.
