Based on the DIN 1587 standard, our type A dome nuts differ by having a solid dome. This allows us to offer a cost advantage to customers but at the expense of a reduced thread length, requiring more precise measurement of the exposed thread on the component.
A little heavier than DIN1587 but still lighter than steel, type A nuts have a cost advantage and all the advantages offered by polyamide (nylon) as the manufactured material.
Lightweight and non corrosive, the type A is specific to Bülte.
A useful alternative to standard hex nuts where protection and safety are desirable.
