DIN 1481 Spring-Type Straight Pin

DIN 1481 slotted spring pins are fasteners for securing parts in holes, providing a tight connection without rotation or displacement.

Specifications of DIN 1481 pins

The DIN 1481 spring pin consists of a cylindrical tube with a slot running along its entire length. The slot allows the spring to compress and expand, adapting to the dimensions of the hole. This feature allows the pin to be installed easily and held securely even with minor deviations in hole diameter. The cylindrical shape ensures even load distribution, making it suitable for heavy-duty operating conditions. The pin meets the requirements of GOST 14229 and ISO 8752.

DIN 1481 pins are made of high-quality steel, including stainless steel, which provides corrosion resistance and durability. This makes them suitable for use in aggressive environments and under increased loads.

Key features:

• Slotted design for adapting to hole dimensions.
• Chamfer at the end for smooth entry into the joint.
• Length and diameter in mm comply with standards (for example, 5×25 mm or 10×50 mm).
• Ability to handle high loads.

Applications of DIN 1481 spring pins

Slotted spring pins are used in mechanical engineering, machine tool manufacturing, construction, instrument making, and other fields where reliable and durable connections are required. They are suitable for securing shafts, axles, bearings, and other parts, ensuring high mounting accuracy and resistance to vibration.

Advantages of DIN 1481 pins:

• High fastening reliability;
• Resistance to vibration and mechanical loads;
• Ease of installation and removal;
• Versatility of application;
• Durability and corrosion resistance.
