Thin Hexagon Nuts — DIN 439

FULLERKREG DIN 439 thin hexagon nuts (also known as half nuts or jam nuts) are manufactured to the DIN 439 standard with a reduced height profile compared to standard hexagon nuts. Their slim form factor makes them ideal for use as jam nuts, lock nuts, and in space-constrained assemblies where a full-height nut cannot be accommodated. Available in four material and surface combinations to cover a broad range of industrial, marine, architectural, and general-purpose applications.
