LAC-M3-1MD
Floating self-clinching, locking thread fasteners LA4, LAC, LAS - Metric
These fasteners feature both locking and non-locking threads, offering convenient load-bearing solutions for thin sheets with up to 0.76mm adjustment for hole misalignment. Their self-clinching design ensures easy assembly by simply squeezing them into prepared holes with a standard press, permanently locking them in place. The floating nut threads extend fully into the retainer shank for enhanced strength and support. Available in non-locking Type A4 and self-locking Type LA4 variants, they provide reliable performance in stainless steel sheets as thin as 0.97mm. Meeting high standards for hardness and torque performance, these fasteners are ideal for a wide range of applications in aerospace and military industries.
