Nylock Jam Nuts are thin hexagon lock nuts with nylon collar insert that resists turning. Nylock jam nuts are also known by the names of nylon insert lock nuts, thin nylock nuts, nylon hex jam nuts, thin nylon stop nuts, etc. Nylock jam nuts cannot be used for high temperature applications. Nylock jam nut dimensions are defined in both metric and imperials sizes with unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN) and iso metric thread profile. These are produced across all material categories and astm specifications.
