Miniature Self-Clinching Fasteners - Types U, UL, FE, FEO, FEOX, FEX - Unified
Our PEM® brand miniature fasteners are designed for compact spaces, offering strong and reusable threads. Featuring self-locking Types FE, FEO, and UL, they ensure secure installations. Compliant with NASM25027 specifications, they meet high standards for thread locking torque performance. The knurled collar, embedded in the sheet, prevents rotation, while the undercut cavity enhances pushout resistance. With a dry-film lubricant for smooth, non-galling operation, these fasteners provide reliable and efficient assembly solutions.
