Floating self-clinching, locking thread fasteners LA4, LAC, LAS - Unified
Enhance the structural integrity of your assemblies with our innovative Locking and Non-locking Thread fasteners. Designed for thin sheets, these components allow for up to .030” adjustment to accommodate mating hole misalignment. Featuring a self-clinching mechanism, installation is quick and effortless with any standard press, ensuring a secure fit with the sheet remaining flush on one side. The unique PEM feature of the floating nut extending fully into the retainer shank provides extra strength and support. In addition to the standard version, we offer a self-locking variant with torque performance meeting NASM25027 specifications. Made from high-quality 300 Series Stainless Steel, our fasteners are suitable for stainless steel sheets as thin as .038”, with hardness up to HRB 88. Compliant with RoHS standards, these fasteners are not only reliable but also environmentally friendly.
