Jack Nuts Assortment (Jack Nuts, Wall Hook, & Friction Wrench) (59120)
by Paulin
Jack nuts are blind fasteners designed for assembly line use in thin, soft, or brittle materials. When tightened, the body collapses to form legs which grip the inside of the mounting surface, leaving a permanent, reusable threaded insert. Variants included in this Jack Nuts Assortment range from #6-32 to 1/4"-20 in coarse thread size. Full assortments of #59120 contain six (6) refills comprised of Hillman item numbers #59121, #59122, #59124, #59126, #59127, and #59129.
