Floating self-clinching, locking thread fasteners LA4, LAC, LAS - Unified
Enhance assembly efficiency with our floating self-clinching fasteners, featuring both locking and non-locking threads for secure installations in thin sheets. Offering up to .030” adjustment for hole misalignment, these fasteners are effortlessly squeezed into prepared holes using a standard press, with the sheet remaining flush on one side for a seamless finish. The unique design, with the threads of the floating nut fully extending into the retainer shank, ensures extra strength and support in assembly. For added security, opt for the self-locking version, meeting NASM25027 specifications for thread locking torque performance. Suitable for stainless steel sheets as thin as .038”, these fasteners, available in Type A4 and Type LA4 variants, provide load-bearing threads with durability up to HRB 88 on the Rockwell “B” scale. Compliant with RoHS standards, these fasteners are a reliable choice for a wide range of applications, including those in the aerospace and military sectors. Explore our complete range of floating fasteners on our website, with many models corresponding to US NASM45938/11 specifications, ensuring quality and compatibility.
