Thin Type Nylon Insert Lock Nuts

Nylon Insert Thin Lock Nut or Nyloc Thin Nut is a nut approx. Half the height of a standard nylon insert lock nut that locks into place by creating pressure on the internal nylon material at the top of the thread against the fastener, so it will not vibrate and become loose. Applications are for light duty or low clearance or for fastening against a hex nut to hold it in place.
