Jack Nut ® - a threaded insert for
all materials
|
|
 |
The JACK NUT threaded insert is a steel blind fastener designed for use in thin, soft, or brittle materials. When tightened, the body
of the jack nut collapses to form legs which grip the inside of the mounting surface, leaving a permanent, reusable threaded insert.
Jack nuts are available in plated steel only, small packs of 5+ or regular packs of 50, 100, 500 or 1000 Jack nuts fastens in a blind hole, but unlike other blind rivet nuts, they are not as hole sensitive. Won't distort or deform soft plastics or thin sheet metals and fastens securely despite burrs or uneven substrate. |
