AC-M3-1
Floating Self-Clinching Fasteners A4, AS, AC - Metric
Locking and Non-locking Threads These fasteners provide load-bearing threads in thin sheets and permit up to 0.76mm adjustment for mating hole misalignment. The self-clinching feature offers fast and simple assembly. The fasteners are squeezed into prepared holes using any standard press. The sheet remains flush on one side, and the fastener is permanently locked in place. Extra strength and support in assembly is obtained by the threads of the floating nut extending fully into the retainer shank (a unique PEM feature). A self-locking version of the fastener is also offered. Thread locking torque performance is equivalent to applicable NASM25027 specifications. Non-locking Type A4 and self-locking Type LA4 fasteners provide load-bearing threads in stainless steel sheets as thin as 0.97mm with hardness up to HRB 88 on the Rockwell “B” scale. Many PEM Type AS and AC self-clinching floating fasteners correspond to sizes in US NASM45938/11 specifications.
