Floating self-clinching, locking thread fasteners LA4, LAC, LAS - Unified
These self-clinching floating fasteners offer a secure solution for assembly, featuring both locking and non-locking threads for versatile applications. Designed to provide load-bearing threads in thin sheets with up to .030” adjustment for hole misalignment, they ensure precise and durable fastening. The self-clinching feature allows for easy installation with any standard press, permanently locking the fastener in place while keeping the sheet flush on one side. With the floating nut extending fully into the retainer shank, enhanced strength and support are guaranteed. The self-locking variant meets stringent torque performance standards, offering reliability in critical operations. Made from 300 Series Stainless Steel, these fasteners are suitable for use in stainless steel sheets as thin as .038”, even with high hardness levels. Whether for industrial or aerospace applications, these fasteners comply with RoHS regulations, ensuring environmental responsibility in your assembly processes.
