New from Marson, the MJN-1 hand-held Quad Leg Nut Installation tool is designed to
effortlessly set quad leg nuts and Jack Nuts® in sizes ranging from 6-32 – 1/4-20, and
M4 – M6. It works by threading the bolt to the quad leg nut, then dropping the component in
the slot of the tool, inserting it into the pre-drilled hole, and squeezing until set. Pressing the
release lever releases the tool. Then tightening the exposed bolt completes the installation.
Jack Nut® is a registered trademark of The Black & Decker Corporation.
