Product Description
The B-M3-1ZI is a self-clinching blind nut designed to provide high-strength metric internal threads in thin metal sheets. The primary advantage of this fastener is its closed-end (blind) design, which creates a barrier against dirt, dust, and moisture while simultaneously preventing screw penetration. By containing the screw within the nut, it protects sensitive internal components from damage caused by over-long hardware. Its self-clinching profile ensures high pushout and torque-out resistance, and because it is installed into a bottomed-out hole, the reverse side of the host sheet remains completely flush and smooth.
Closed-End Design: Seals the assembly against environmental contaminants and protects internal parts from screw damage.
Flush Rear Surface: Ensures the back side of the metal panel is smooth and unobstructed for aesthetic or clearance requirements.
High Strength Threads: Provides superior load-bearing capabilities compared to standard tapped holes in thin materials.
Permanent Attachment: Becomes an integral part of the assembly once squeezed into place, eliminating the risk of loose or lost hardware.
Corrosion Protection: Carbon steel construction is finished with zinc plating for enhanced durability.
