In engineering, ISO 7035 corresponds to , the standard for slotted castle nuts used with a cotter pin to prevent loosening due to vibration. It is common in the automotive and machinery industries.
In the global industrial landscape, many facilities are transitioning from regional German standards to international ISO guidelines. The direct historical predecessor and closest equivalent to ISO 7035 is .

Unlike chemical thread-lockers or nylon insert nuts, an ISO 7035 nut relies on a physical interference fit. When the nut is torqued down onto a bolt with a pre-drilled radial hole, a cotter pin (split pin) is inserted through the slots and the bolt hole, then bent flat. This completely prevents the nut from backing off the thread under extreme dynamic load conditions. 2. ISO 7035 vs. DIN 935: The Conversion Differences
Unlike standard hexagonal nuts, an ISO 7035 nut features built-in slots (or "crenels") cut into a cylindrical crown at the top of the nut. This design is engineered specifically for positive locking systems. When the nut is threaded onto a bolt or axle that has a pre-drilled hole, a split cotter pin or safety wire is inserted through the slots and the hole. This mechanical physical barrier physically prevents the nut from backing off or loosening over time.

A hexagon slotted castle nut features vertical slots cut into a cylindrical crown atop a standard hex body. These specialized slots are designed to accommodate a cotter pin or safety wire, which passes directly through a pre-drilled hole in the mating axle or shaft. This physical block makes it practically impossible for the nut to spin free, offering an exceptionally reliable locking method where conventional friction-based nylon insert nuts might fail due to environmental heat or aging.
