What is a PEM screw?

PEM® Fasteners. 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.

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.

In this regard, how do you install PEM studs?

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 do you remove PEM nuts?

The next couple steps will do that for you. Step 2: Insert a 5/16″ bolt with flat washer through the PEM Nut Removal tool and thread the bolt into the PEM nut. Step 3: Tighten the 5/16″ Bolt until the removal tool is snug on the removal tool and the removal tool is flat to the aluminum around the pem nut.

What is a Nutsert?

Nutserts® Nutserts® are inserts that, when installed, provide threads in materials too thin for tapping, or in blind holes. Nutserts® are ideal for use in areas where sheet metal screws can’t achieve the clamp load and pull-out values required.

How do you install a self clinching stud?

What is a self clinching stud?

Self-Clinching Studs. Self-Clinching studs are pressed into a hole in a sheet to be installed, this embeds the head of the stud creating a secure lock into the sheet with high torqure-out and pushout resistances.

How do clinch nuts work?

Forcing the clinching ring into softer material, with an arbor press or by tightening a screw through the hole, causes it to plastically deform (swage) into the annular recess in the shank. This locks the nut into the hole.

How do you use a rivet nut?
