Hexagon Thin Nut (DIN439) is a low-profile metric hex nut designed for applications where limited space, reduced nut height, or locking adjustment is required. Compared to a standard hexagon nut, a thin nut has a lower height, making it suitable for compact assemblies, adjustment points, and applications where a full-height nut may not fit.

Also commonly known as a jam nut or lock nut, Hexagon Thin Nut (DIN439) can be used together with another nut to help lock the fastening position. When tightened against a standard nut, it helps create a jamming effect that can reduce loosening caused by vibration, movement, or adjustment changes. This makes it suitable for machinery, automotive, construction, metal fabrication, equipment assembly, threaded rod systems, and industrial maintenance applications.

With Steel, Stainless Steel 304 (A2), and Stainless Steel 316 (A4) material options, Hexagon Thin Nut (DIN439) can be selected based on strength requirement, corrosion resistance, working environment, and application needs.
