What does PEM nut stand for?
Power Entry Module. PEM nut or self-clinching nut.
What is a PEM in manufacturing?
PEM brand fasteners are hardware components that provide threaded attachment points for thin parts like sheet metal brackets and printed circuit boards (PCBs). The fastener (in this case a nut) has been pressed into a thin bracket. The bracket is attached to a mating part with a screw.
How do you install a self clinching nut?
Installation is neat and easy, simply locate the fastener into a pre-prepared (punched or drilled and reamed) hole and apply a parallel squeezing force to embed the fastener into the panel. Self-Clinching fasteners work by utilizing a special clinch feature.
How does a PEM nut work?
HB-4 PennEngineering • www.pemnet.com roadly defined, a self-clinching 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 do you fit clinch nuts?
Place the Nuts spigot end into the hole on the side opposite the mating face. So that nut rests on the serrations. Ensure both plate and nut are aligned along the same axis. If the nut is not seated ‘square’ in the hole, the joint will be imperfect and mating threads will mis-align.
How do you install a PEM 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.
Are there any PEM nuts that are self clinching?
PEM® brand self-clinching nuts install permanently in aluminum, steel or stainless steel sheets. Many PEM self-clinching nuts in this bulletin are dimensionally equivalent to nuts manufactured to NASM45938/1 specifications.
What kind of nuts are used in stainless steel sheets?
SP™, PEM 300® nuts provide strong load-bearing threads in stainless steel sheets as thin as .030”/0.8 mm- PAGES 4 and 5 PEM RT® free-running locknuts are free-running until clamp load is induced.
What kind of nut is a 6 / 6 wing nut?
These nylon 6/6 wing nuts are chemical resistant, nonconductive, and lightweight. Brass wing nuts are corrosion resistant in wet environments and electrically conductive. The flange distributes the load over a large area and reduces stress where the nut meets the material surface.
Which is stronger PTFE nuts or nylon 6 / 6 nuts?
They withstand temperatures up to 550° F and resist acids, bases, and salt solutions. Fiberglass nuts are stronger than nylon 6/6 nuts. They resist acids, solvents, salt water, and oil. PTFE nuts withstand temperatures up to 500° F. They resist oil, grease, detergents, and most mineral acids.
