Studs And Pins For Sheetmetal

Concealed Head – Types CFHA, CFHC, CHA, CHC

PEM self-clinching concealed-head studs install permanently in steel or aluminum sheets as thin as .062" / 1.6mm to provide strong and reusable threads for mating hardware in a wide range of thin-metal assembly applications.

Flush-Head - Types FH, FH4, FHA, FHP, FHS

Available in steel, aluminum and stainless steel, PEM standard flush-head studs are designed to be installed in sheets as thin as .040" / 1 mm.

Flush-Head Studs with X-Press™ Thread Profile - Type FHX

Self-clinching, flush-head studs with X-Press™ threads are typically used with push-on or other plastic fasteners. The course thread design of the thread reduces assembly time and provides high retention force.

Flush-Head, Low Displacement - Types FHL, FHLS

Flush, low-displacement head studs install closer to the edge of a sheet than PEM Types FH/FHS studs without causing that edge to bulge.

Heavy Duty, Non Flush - Types HFH, HFHB, HFE, HFHS


Heavy duty studs are designed with an enlarged head diameter which projects above the sheet metal and provides maximum pull through in sheets as thin as .040" / 1mm.

Hard Panel Studs - Type HFLH™

PEM® Type HFLH installs into thin, harder, high strength steel materials. They allow for overall weight reduction for all vehicles. As well as address environmental / recycle concerns, provide lower installed costs, and allow component standardization.

High Tensile Strength, Non Flush - Types HF109, HFG8

Studs and Pins

Heavy duty high tensile strength studs are manufactured for the most demanding applications from medium carbon alloy steel, then heat-treated to high strength and hardness qualities.

Thin Sheet, Non Flush - Types TFH, TFHS

Studs and Pins

Thin sheet studs are for sheets as thin as .020 inches / 0.51 mm. They may also be used in thicker sheets where flush head studs are not required. TFH studs are installed in the sheets in the same manner as flush-head studs; however different punches and anvils are required.

Thin Sheet, Non Flush - Type THFE

Studs and Pins

The clinch design provides high-strength in sheets as thin as .031" / 0.8 mm. The enlarged head diameter reduces stress on the panel and the thicker head allows for a larger hole in the attached panels. The THFE is recommended for use in steel or aluminum sheets HRB (Rockwell "B" Scale) 85 or less and HB (Hardness Brinell) 165 or less.

Unthreaded, Flush - Types TP4, TPS, TPXS

Studs and Pins

Flush-head pilot pins satisfy a wide range of positioning, pivot, and alignment applications. The chamfered end makes mating hole location easy.

Installs Into Stainless - Types FH4, FHP, TP4

Studs and Pins

One of the very basics of self-clinching is that the fastener must always be harder than the host sheet to ensure proper and permanent installation. Threaded types FH4, FHP and unthreaded type TP4 are specifically designed for installation into stainless steel sheets as thin as .040'" / 1 mm.

microPEM®, Self-Clinching - Type MPP™

Studs and Pins

Type MPP, self-clinching micro pins are ideal for today's compact electronic assemblies. They can be installed into a variety of sheet materials up to HRB 92 / HB 195 in hardness and they offer excellent corrosion resistance.

Swaging Collar Studs, Non Flush - Type SGPC™

Studs and Pins

Type SGPC swaging collar studs can be installed into most panel material, provide strong torque-out resistance and are suitable for close centerline-to-edge situations. These studs can also accomodate multiple panels as long as the total thickness does not exceed the maximum sheet thickness.
