Welcome To Our Jack Nut Collection

The Jack Nut, also called the ‘Molly Nut’, is a ‘light-duty’ alternative to the Plus Nut. Featuring a flat head and slotted body, the Jack Nut is a blind nutsert designed for soft or brittle materials such as plastic, paper, or glass. During installation, the body of the Jack Nut crimps creates a permanent and reusable thread, while four legs expand behind the parent material, providing excellent pull-out resistance, particularly in soft materials. 

RivetLab offers steel Jack Nuts in various grip ranges from M4 to M6 and the ¼” imperial size, available in packs starting from 50 pieces. In addition to Jack Nuts, we stock various other rivet nuts and fasteners. For large quantities, please don't hesitate to contact us directly or email sales@rivetlab.com to discuss bulk discounts.
