PEM SMTSK unthreaded standoffs permanently surface mount on printed circuit boards to enable quick attachment and removal of stacked components without requiring screws or tools. Their barrel design allows for a stacked board or panel to be slipped easily into place and then detached by simply sliding the component sideways and lifting it off. These…

PEM self-clinching SH nuts and HFLH studs from PennEngineering successfully install in high-strength thin steel sheets to provide permanent threads for mating hardware in automotive component attachment applications. These hard panel nuts and studs manufactured from hardened alloy steel ultimately exhibit stronger thread strength compared with conventional fasteners. The fasteners additionally eliminate the environmental-related issues…

SI inserts permanently install in plastic assemblies to provide durable and reusable metal threads for mating hardware and allow for repeated disassembly and re-attachment whenever required. By promoting quick and easy access to an assembly, SI inserts offer highly practical joining solutions in contrast to fixed and unyielding methods, such as adhesives or rivets. Repeated…

PEM SFN spinning flare nuts from PennEngineering become permanently captivated upon installation in thin metal sheets and, when paired with a self-clinching stud or other fixed externally threaded hardware, can eliminate all loose fasteners (including flange nuts) in attachment applications. These one-piece, flanged hex nuts additionally will spin freely in a sheet enabling quick attachment…

ATLAS SpinTite blind threaded inserts from PennEngineering provide strong, permanent, and reusable threads in thin sheet materials where only one side is accessible for hardware installation. Installation is performed from the accessible “front” side using spin-spin tooling technology. The inserts then become permanently mounted on the “back” side to accept a mating screw for final…

PEM TSO4 self-clinching threaded standoffs from PennEngineering offer reliable fastener solutions to securely stack or space components in ultra-thin stainless steel assemblies. These hardened stainless steel fasteners clinch into stainless sheets as thin as 0.025 in. / 0.63 mm and become permanent parts of an assembly. The standoffs ultimately will reduce the amount of required…

Mating screw applications that require secure attachments can rely on self-clinching locknuts, which self-lock threads to reduce loosening and can be removed repeatedly without affecting performance. By Michael J. Rossi, Marketing Services Supervisor, PennEngineering By all measures, the hardware specified to attach components is expected to perform reliably in service. But sometimes application-related factors —…

Aluminum and stainless steel microPEM® TackSert® pins from PennEngineering provide cost-effective alternatives to micro screws for attaching top panels to base panels or chassis in compact electronic assemblies.  They will attach top panels of any material to a base or chassis manufactured from common cast metals (such as magnesium and aluminum) or plastics (such as…

The PEM® VariMount® fastening system from PennEngineering® enables the use of PEM® self-clinching fasteners for attachment applications in composites, plastics, metal, and any rigid material or panel. The system integrates a self-clinching nut, stud, or standoff pre-installed permanently into a steel or stainless steel base plate. The base plate with multiple radial holes effectively becomes…
