Floating Self-Clinching Fasteners A4, AS, AC - Unified
These fasteners offer a versatile solution for creating load-bearing threads in thin sheets, with the ability to accommodate up to .030” of adjustment for hole misalignment. Featuring a self-clinching design, they allow for quick and easy assembly using a standard press. The floating nut extends fully into the retainer shank, providing extra strength and support during installation. Made of 400 Series Stainless Steel, they are suitable for use in sheets as thin as .038” with hardness up to HRB 88. Available in both non-locking and self-locking variants, they meet stringent performance standards, including NASM25027 specifications. Designed for durability and reliability, these fasteners are ideal for a wide range of applications in aerospace, military, and industrial settings.
