DIN 6334 Hexagonal Coupling Nuts, also known as extension nuts, are elongated, fully threaded hexagonal nuts designed to join two externally threaded fasteners, such as threaded rods. These coupling nuts are typically three times the major diameter of the thread in height, providing a secure and stable connection. Available in sizes ranging from M5 to M30, they are commonly manufactured in A2 and marine-grade A4 stainless steel for enhanced durability and corrosion resistance.
DIN 6334 is a German standard that outlines the dimensions, design, and performance specifications for flanged blind rivet nuts. These fasteners are ideal for creating strong, threaded connections in thin panels or materials where access is limited to only one side. The standard ensures consistent quality and reliability, covering various sizes and tolerances for dependable installation. DIN 6334 coupling nuts are widely used in automotive, electronics, and manufacturing industries, providing secure connections in demanding applications where precision and strength are critical.
