What is DIN439 Hex Thin Nut？

DIN 439 is a standard specification for hexagon thin nuts made of various materials such as stainless steel, brass, and plastic. These nuts have a reduced thickness compared to regular hexagon nuts and are commonly used in applications where space is limited. They are also known as half nuts or jam nuts and are often used in conjunction with regular hex nuts or other fasteners to lock them in place. The DIN 439 specification ensures that the nuts meet specific dimensional requirements, including thread size, pitch, and height.
