Always torque the ISO 7035 nut to the design load specifications using a calibrated torque wrench. Do not loose-fit the nut simply to align the slots.
ISO 7035 PDF: Comprehensive Guide to Hexagon Slotted Castle Nuts
is an international standard that specifies the characteristics of hexagon slotted nuts with a reduced shaft, commonly referred to as "castle nuts" or "crown nuts". These nuts feature vertical slots—or a "crown"—on one end, designed to be used in conjunction with a cotter pin or safety wire. iso 7035 pdf
ISO 7035 specifies the test methods for determining the tensile properties of metallic fibers and yarns, including their tensile strength, elongation, and elastic modulus. The standard covers metallic fibers and yarns made from various materials, such as steel, copper, and aluminum, used in textiles, composites, and other industrial applications.
is technically defined as part of the ISO 703 series, which relates to Hexagon socket set screws (often referred to generically as Allen screws or grub screws). While many ISO standards focus on the dimensions of the screw head or the length of the thread, ISO 7035 specifically addresses the Hexagon Sockets . Always torque the ISO 7035 nut to the
Follow these key procedural guidelines to ensure the positive locking mechanism functions correctly:
Used when non-magnetic properties or specific electrical conductivity is required. Strength Classes These nuts feature vertical slots—or a "crown"—on one
The ISO 7035 standard defines the specifications for (also known as crown nuts) with metric threading, typically with a nominal thread diameter ranging from M8 to M80. These nuts are designed for high-stress applications where the fastener must be secured against loosening due to vibration or torque.
