AttaBox non-metallic industrial enclosures offer significant economic savings over metallic alternatives such as stainless steel while providing comparable or superior physical properties. AttaBox models are available…
Self-clinching nuts and studs provide permanent threads in thin steel sheets
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…
Inserts for plastic assemblies provide reusable metal threads
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 eliminate loose fasteners in thin metal sheet attachment applications
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…
Two-part epoxy adhesive for structural bonding has long pot life
Master Bond EP21ND-LP was created for structural bonding applications involving large surface areas. It has an advantageously long working life of 2-4 hours at 75°F for a 100 gram mass. Its smooth paste consistency makes it convenient to apply and use. Shore D hardness is 70-80 when mixed in a one to one mix ratio…
ATLAS SpinTite blind threaded inserts provide permanent threads in thin sheet applications with only one-sided access
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…
Epoxy features low coefficient of thermal expansion
Master Bond EP30LTE-2 has been developed for joining dissimilar substrates exposed to thermally or mechanically induced stresses. It can be used for sealing, coating and encapsulating, especially for small to medium sized castings where a very low coefficient of thermal expansion (CTE) is required. EP30LTE-2 is a highly dimensionally stable epoxy system with low linear…
Self-clinching fasteners stack and space components securely
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…
When adhesives go wrong
Too often the adhesive selection for a medical device is left to the end of a project. It doesn’t help that there are so many adhesives as to make the choice overwhelming. With so many potential negative outcomes, here are tips on making the right choice. Tony Kaufman, New Business Ventures in 3M’s Critical and…
