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 component attachment. The “blind” installation capability especially suits applications such as tubing, extrusions, and others where access to the back side is either limited or nonexistent. Continue reading

PEM® TSO4™ Self-Clinching Threaded Standoff Fasteners Securely Stack or Space Components in Ultra-Thin Stainless Steel Assemblies

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 .025” / 0.63mm and become permanent parts of an assembly. The standoffs ultimately will reduce the amount of required hardware in an assembly, promote thinner and lighter designs, and minimize typical handling issues associated with loose hardware.

New Stainless Steel PEM® TK™ TackSert® Pins Ideal Alternatives to Screws for Attaching Thin Panels in Assemblies

New stainless steel PEM® TK™TackSert® pins from PennEngineering® introduce ideal alternatives to screws for attaching thin panels in assemblies. They can securely attach panels of any material to base panels manufactured from common casting materials (such as AZ91D) or plastics (such as ABS and printed circuit boards). Unique design features promote reliable performance in service.

PEM TK TackSert pins deliver multiple advantages over screws by eliminating any need for mating threads from tapped holes or inserts and the rework frequently required due to screw cross-threading and driver bit “cam-out.” Patches intended to prevent fastener loosening in service are unnecessary.

Among pin design features, a tapered tip assists in pin location to enable easier alignment into a base panel, a specially engineered diagonal broaching knurl (instead of threads) creates a firm interference fit without hole-tolerance issues, and a low-profile head minimizes protrusion on the attached panel.

The pins are offered in a variety of lengths and can successfully attach sheets with thicknesses from .067” / 1.7mm to .185” / 4.7mm, depending on pin length. For plastic bases, simple press-in installation without using heat or ultrasonics is performed by preparing properly sized mounting holes in the top sheet and base panel, placing the pin through the hole in the top sheet and into the through or blind mounting hole of the base panel, and then applying sufficient squeezing force using punch and anvil until the head of the pin contacts the top sheet. Pins can even be installed automatically for high-volume jobs.

PEM® FHX™ Self-Clinching Flush-Head Studs with X-Press™ Thread Profile Quickly Mate with Push-On Plastic Fasteners or Wire Ties

PEM® FHX™ self-clinching flush-head studs from PennEngineering® uniquely feature an X-Press™ thread profile enabling 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. The thread design additionally accommodates paints and coatings without compromising fastener performance in service.

The studs install permanently in metal sheets as thin as 1mm. They press easily into place using any standard press or can be installed automatically during the stamping process using an automated PEMSERTER® press equipped with in-die technology. Upon installation, the head of the stud mounts flush in the metal sheet for a clean and attractive finished appearance. Domed stud heads are available on special order.

The studs are manufactured from hardened carbon steel and finished with zinc plus clear chromate as standard or a rust-preventive oil finish as an option. They can be supplied in 5mm or 6mm thread sizes and in lengths from 10mm to 25mm.

PEM® PFC4™ Self-Clinching Captive Panel Screws Enable Easy Access to Stainless Steel Enclosures Without Loose-Hardware Risks

PEM® PFC4™ self-clinching captive panel screws from PennEngineering® install permanently into stainless steel enclosures to enable easy access whenever necessary and eliminate risks associated with loose screws. The captivated screw remains reliably in place where designed in a door or panel and will not loosen, fall out, or damage internal components. Expanding their application potential, these spring-loaded fastener assemblies comply with UL 60950 equipment access standards. Continue reading

New microPEM® Flaring Standoffs for Compact Electronic Assemblies Provide Ideal Miniature Fastener Solutions to Attach and/or Space Components

New microPEM® MSOFS™ flaring standoffs from PennEngineering® provide ideal miniature fastener solutions to attach and/or space components in compact electronic assemblies. They install permanently in thin panels of any hardness and material, including stainless steel, other metals, plastics, and printed circuit boards. A unique flaring feature adds value by allowing for installation into multiple panels. Continue reading

PEMHEX® Self-Clinching Prevailing Torque Locknuts Integrate Nylon Hexagonal Insert to Prevent Mating Screws from Loosening

PEMHEX® self-clinching prevailing torque locknuts from PennEngineering® integrate a trademarked blue nylon hexagonal insert designed to prevent mating screws from loosening in service due to vibration, thermal cycling, or other application-related factors. The reusable locking element provides the necessary torque resistance to securely grip mating screws and allow for their repeated installation and removal over time. The primary advantage of this locking method is to greatly reduce the possibility of conductive debris being generated from repeated installation and removal of mating screws. Thread-locking torque performance is equivalent to applicable NASM25027 specifications. Continue reading

Aluminum and Stainless Steel microPEM® TackSert® Pins for Compact Electronics Provide Cost-Effective Alternatives to Screws for Attaching Top Panels in Assemblies

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 ABS and printed circuit boards). The pins ultimately eliminate many of the costs and issues associated with screws and integrate unique design features promoting reliable and effective performance. Continue reading
