What is a self clinching standoff?
Self-clinching standoffs provide a solution when design engineers need to space panels and components in their metal enclosures. They are used to stack parts or keep components a defined distance from the panel in which they are installed.
What is a PEM standoff?
PEM® KEYHOLE® standoffs are designed so that a PC board or panel can be quickly slipped into place and then removed from an assembly by simply sliding the board sideways and lifting it off. Type SKC can be used for spacing or hanging of replaceable components.
What are self clinching fasteners?
Broadly defined, a self-clinching fastener (also known as clinch or captive fastener) is any device, usually threaded, that, when pressed into ductile metal, displaces the host material around the mounting hole, causing it to cold flow into a specially designed annular recess in the shank or pilot of the fastener.
How are PEM standoffs installed?
PEM® self-clinching standoffs install with a squeeze in properly sized round mounting holes and become permanently mounted in the thin sheet. These standoffs enable components to be stacked or spaced away from the panel in an assembly. All standoffs are installed into round mounting holes.
What are clinch nuts?
Clinch nuts are self-clinching, internally threaded nuts that are pressed into the base material. Often times, these high strength fasteners are used in material that is too thin to tap threads.
How do you use a PEM fastener?
PEM® Brand Fasteners Installation Demo
- Prepare properly sized mounting hole in sheet.
- Place shank of nut into mounting hole, preferably the punch side.
- With punch and anvil surfaces parallel, apply squeezing force until the head of the nut comes into contact with the sheet material.
How do you install a self clinching stud?
PEM® self-clinching studs are easily installed by placing them in properly sized holes in sheets and squeezing into place with any standard press: Install permanently in aluminum, steel or stainless steel in sheets as thin as . 020” / 0.51 mm. High torque-out and pushout resistances.
How are clinch nuts installed?
Clinch nut installation is achieved when the self clinching nut is pressed into ductile metal, which displaces the host material around the mounting hole, causing it to cold flow into a specially designed annular recess in the shank pilot of the fastener.
What is PEM hardware?
PEM® brand fasteners utilize self-clinching, broaching, flaring, surface mount, or weld technology to provide strong, reusable, and permanent threads and mounting points in thin sheet metal, P.C. board materials, and other ductile or non-ductile thin material.
