AC-M3-1
Floating Self-Clinching Fasteners A4, AS, AC - Metric
These fasteners provide essential load-bearing threads in thin sheets and allow for adjustment of up to 0.76mm for mating hole misalignment. Featuring a self-clinching design for quick and easy assembly, they are simply squeezed into prepared holes using a standard press, with the sheet remaining flush on one side while the fastener is securely locked in place. The floating nut extends fully into the retainer shank for added strength and support, with a self-locking option available for enhanced security. These fasteners, made of 300 Series Stainless Steel, are ideal for use in stainless steel sheets as thin as 0.97mm, meeting stringent hardness requirements. Their performance is in line with NASM25027 specifications, and they correspond to sizes in US NASM45938/11 standards, ensuring reliability and compliance.
