Dome Nyloc Nuts Zinc Plated DIN986

Dome Nyloc Insert Nuts are manufactured to DIN986 standard, but share many of the characteristics of DIN1587 Dome Nuts.

The dome nyloc nut is a torque prevailing nut which uses a plastic nylon insert which is located towards the nut, therefore reducing its inner diameter. This deforms over the mating thread, capturing the bolt or screw and provides a locking feature, causing resistance or prevailing torque, keeping the nut locked into position and resistant to vibration.

The domed design feature of the nut means that the screw threads do not damage the nylon section.
