LAC-M4-1MD
Floating self-clinching, locking thread fasteners LA4, LAC, LAS - Metric
These self-clinching fasteners provide a reliable solution for creating load-bearing threads in thin sheets, offering up to 0.76mm of adjustment for hole misalignment. With a simple press-fit installation process, they securely lock into place, ensuring stability in assembly. Featuring a unique design with the floating nut extending fully into the retainer shank, they offer enhanced strength and support. Available in both non-locking and self-locking variations, these fasteners are suitable for use in stainless steel sheets as thin as 0.97mm, meeting stringent hardness requirements. Corresponding to US NASM45938/11 specifications, they are ideal for aerospace and military applications. For a visual demonstration of their assembly, you can view our animation. Compliance with RoHS regulations guarantees their environmental sustainability.
