PEM® brand miniature fasteners are designed to fit into tight spaces while offering robust, reusable threads. Featuring self-locking capabilities, types FE, FEO, and UL ensure secure fastening with thread locking torque performance meeting NASM25027 standards. Some sizes can even adhere to NASM45938/7 specifications. With a knurled collar embedded in the sheet, rotation is prevented, and pushout resistance is enhanced by filling the undercut cavity with displaced sheet material. The dry-film lubricant applied to these stainless steel fasteners guarantees smooth, non-galling torque performance for reliable locking and reusability. Immediate visual indication of proper installation is provided, making them ideal for applications where precision and durability are essential.
