A DIN 439 mild steel nut is a low-profile hexagonal fastener, commonly referred to as a jam nut, thin nut, or half nut. It is approximately half the height of a standard hex nut (like DIN 934).
When made from mild steel (typically property class 04), it is designed for light-to-medium duty applications where space is restricted or high clamping force is not the primary requirement.
