Product Description
The BS-0420-2 is a stainless steel self-clinching blind nut designed to provide high-strength internal threads in thin metal sheets. This fastener features a closed-end (blind) design, which acts as a protective 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.
Environmental Protection: The closed-end design seals the assembly against contaminants and prevents external leakage.
Component Safety: Limits the depth of screw travel, protecting internal circuitry or fragile parts from mechanical damage.
Corrosion Resistance: 300 Series Stainless Steel construction provides enhanced durability in demanding or corrosive environments.
Flush Rear Surface: Ensures the back side of the metal panel remains unobstructed and aesthetically clean.
Shank Code 2: Specifically engineered for installation into thicker sheets starting at 1.4 mm / .055 in.
