SI® threaded inserts from PennEngineering® provide durable and reusable metal threads in plastic materials to accept mating hardware and subsequently allow for access to an assembly whenever required. Unlike fixed and unyielding joining methods, such as adhesives or rivets, the inserts ultimately offer the capability to disassemble and re-attach plastic components easily and quickly without damaging the threads, compromising attachment integrity, or otherwise adversely impacting an assembly. Brass, stainless steel, and aluminum types are available as standard.
New PEM® self-clinching flush-head studs integrating unique X-Press™ threads enable quick mating with push-on plastic nuts, wire tie products, or other plastic fasteners in thin metal assemblies. Their coarse thread design – larger threads relative to the stud’s diameter – reduces assembly time by allowing for easy mating of plastic parts and promotes especially high retention force of the stud upon installation. The thread design additionally accommodates paints and coatings without compromising fastener performance in service.
PennEngineering® (Danboro, PA, USA) has entered into a license agreement with EJOT® GmbH & Co. KG, Industrial Fastener Division (Bad Laasphe, Germany) covering EJOT® PT® and Delta PT® screws for plastic applications. The agreement allows PennEngineering to use EJOT® technical information, patent rights, and trademarks in connection with the manufacture and sale of PT® and Delta PT® screw products.
New PEM® ReelFast® surface mount spring-loaded captive panel screws (Type SMTPFLSM™) from PennEngineering® install precisely and permanently where designed on printed circuit boards to provide secure attachment and allow for subsequent access whenever necessary. These all-metal captive screw assemblies mount in one piece on boards using the pick-and-place method and will install in the same manner and at the same time as other surface mount components prior to the automated reflow solder process. The captive screw technology eliminates issues and risks associated with the handling, installing, and potential loosening of standard screws and can be easily actuated with the combination Torx®/slot drive.
