New microPEM® TackScrew™ fasteners from PennEngineering® integrate proven self-clinching technology for permanent sheet-to-sheet attachment while also incorporating a unique thread-like feature to allow fastener removal when necessary. This combination adds functionality to the original microPEM TackPin™ fastener product line for thin sheet attachment applications, especially compact electronics. TackScrew fasteners can even be reinstalled one time if desired.
These hardened stainless steel Type TS™ fasteners ultimately can serve as highly practical solutions to attach a top sheet or panel to a base material in applications ranging from laptops, notebooks, and tablet computers to smart phones, gaming and hand held devices, and wearable electronics, among others. As suitable replacements for micro screws, TackScrew fasteners will not require the added costs of locking patches, threaded inserts, tapped holes or driver bits for initial installation, or potential rework due to cross threading and driver bit “cam out.” The clinch technology resists vibrational loosening in service and the fastener’s low-profile head can add cosmetic value.
