DIN 1481 Spring Type Flat Pins (Coil Pins), Heavy Type - ISO 8752 Spring Type Flat Pins, Slotted, Heavy Duty

Roller pins, or flat slotted spring pins, defined in the DIN 1481 standard published by the German Institute for Standardization (DIN), are hollow and divided along the entire length of the pin. It is used to align and fix components relative to each other. The resting diameter of the pin is larger than the hole diameter in which it will be inserted. When inserted into the hole, the pin tightens to fit the smaller diameter. The force applied to the wall of the hole tightens the seat as the pin tries to expand to the original diameter. This creates holding power against shock and vibration. At least one end of the pin is threaded to facilitate pin insertion.

Similarly, the ISO 8752 standard published by the International Standards Organization (ISO) describes the characteristics of a heavy-duty, corrugated spring-type flat pin with a nominal diameter of 1 mm to 50 mm, made of steel or austenitic or martensitic stainless steel (ISO 8752). Spring type flat pins - Slotted, heavy duty).

The requirements for heavy-duty, slotted spring pins (coil pins) are included in the DIN 1481 standard under the following headings:

• Mechanical properties of stainless steel for heavy type slotted spring flat pins (coil pins)
• Chemical composition of stainless steel for heavy type slotted spring flat pins (coil pins)
• Mechanical properties of steel for heavy type, slotted spring flat pins (coil pins)
• Chemical composition of steel for heavy type slotted spring flat pins (coil pins)

Stainless steels are divided into three groups as austenitic, ferritic and martensitic. Austenitic steel is by far the most common type (more than 90 percent of commercial fasteners). Steel groups and strength classes are indicated with four-digit letters and numbers as shown in the table in the standard.

Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, within the scope of DIN 1481 standard, for heavy, spring type flat pins (roll pins) and within the scope of ISO 8752 standard. also provides testing services for slotted, heavy duty, spring type flat pins.
