Nylon Insulating Sleeve Washers

These washers are designed to insulate screw threads, effectively blocking electrical currents and preventing short circuits. When installed in through holes, they form a protective barrier between the screw threads and the mating surface. This barrier not only safeguards against electrical interference but also extends the lifespan of your assembly by reducing the risk of galvanic corrosion — a phenomenon where contact between two dissimilar metals accelerates rusting.
