Self-Clinching Nuts and Studs work with hard sheet materials.

December 8, 2014

PEM® self-clinching nuts and studs, which include SH™ hard panel nuts and HFLH™ hard panel studs, are designed for permanent installation into hard sheet materials and suit automotive component attachment applications. Manufactured from hardened alloy steel, products enable close-to-edge mounting without risking panel buckling, eliminate need for embossing operations, and can be installed automatically using standard press or in-die technology.

Heavy-Duty Studs clinch permanently into thin metal sheets.

August 29, 2014

Available in lengths up to 2 in., PEM® Type THFE™ Studs feature enlarged head diameter that distributes axial tightening force over wide area to minimize compressive stress on host panel, optimize pull through performance, and develop full thread strength. Self-clinching studs install into steel or aluminum sheets as thin as .031 in. with hardness of HRB 85 or less on Rockwell B scale and HB 165 or less on Hardness Brinell scale. Thread sizes range from ¼-20 through 5/16-18 and M6–M8. Read More

Self-Clinching Studs attach thin metal assemblies.

March 13, 2014

Designed to install permanently using standard press, PEM® Self-Clinching Threaded Studs include flush-head models for use in aluminum or stainless steel sheets as thin as .040 in. and stainless versions for corrosion resistance in even thinner stainless steel assemblies. Other types include low-displacement flush head studs for close-to-edge installation; non-flush studs for sheets as thin as .020 in.; and heavy-duty studs whose heads project above sheet to distribute axial tightening force.

Self-Clinching Flush-Head Studs meet corrosion resistance needs.

April 26, 2013

For attachment applications requiring corrosion resistance, PEM® Type FHP™ self-clinching flush-head studs are manufactured from A286 stainless steel and install permanently into stainless steel sheets as thin as .040 in. Products mount flush and permanently, becoming integral parts of assembly with only mating nut required for final component attachment. Studs can be supplied in thread sizes No. 4–40 through No. 10–32 and M3–M5 and in range of 10 standard lengths. Read More

Swaging Collar Studs accommodate multiple panels, materials.

February 22, 2011

Used for attaching dissimilar panel materials and/or multiple panels, PEM® Type SGPC(TM) studs torque-out resistance and allow for close centerline-to-edge distance to suit limited-space applications. Studs install into sheets as thin as .024 in. and in multiple panels whose total thickness does not exceed max sheet thickness of .047 in. Manufactured from 300 Series stainless steel, products can be used in sheets of any hardness and comes in thread sizes No. 2-56 through ¼-20 and M2.5-M6. Read More
