The mid-range Pemserter Tech2t automatic press for installing self-clinching fasteners offers increased production rates and improved insertion quality
More secure attachment of vehicle components
Autospec self-clinching fasteners are designed to reduce the number of parts needed for attachment, accelerate assembly, and promote neater and lighter component designs
The RoHS-compliant studs can install permanently in copper sheets as thin as 1.3mm and have been engineered for high-strength attachment applications.
When they are properly installed, pushout values up to 1115N and torque-out values up to 25Nm can be realised, depending on the fastener's thread size and thickness of the host copper sheet.
Improved pull through resistance is enabled by their large-head design, which allows the stud's head to project above the sheet material and distribute the axial tightening force over a wide area.
Installation is easily accomplished by placing the studs in punched or drilled holes in the copper sheet and squeezing them using any standard press.
Sufficient squeezing force embeds ribs on the head of the stud into the sheet to permanently lock the fastener in place.
The studs become an integral part of an assembly.
Thread sizes for PEM Type HFHB busbar clinch studs range from 10-32 to 3/8-16 and M5 to M10.
Studs can be specified in a variety of lengths up to 50mm.
Complete specifications including electrical resistance data and CAD drawings (in most formats) for these fasteners are available free for downloading from the PennEngineering website.
