Pal Nuts or Counter Nuts (DIN 7967)
Pal nuts are made to DIN 7967 and most commonly referred to as a Counter Nut, stamped sheet metal Check-Nuts or self locking Counter Nuts.
These locknuts are made from a spring-like steel which allows them to distort under load pressure, before returning to their original shape in the threaded area.
They are very lightweight and host a low profile and the ability to be tightened with an internal wrench or fingers. This provides a vibration resistant locking action whilst remaining usable in small and tricky areas suffering from space restrictions.
Pal Nuts or Counter Nuts are manufactured as standard in Steel Galvanised, Steel Zinc, Self Colour and A2 or A4 Stainless Steel, with other materials also available.
Sizes range from M4 to M80 as standard, with specials including M84 and M85, available to order.
Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
