Grooved pin, full length parallel grooved with pilot DIN1470 ISO 8740

——

These solid cylindrical pins feature multiple parallel grooves pressed along their entire length. When driven into a pre-drilled hole of the appropriate diameter, the displaced material from the mating part flows into these grooves, creating a strong mechanical interlock. The pilot end facilitates easy insertion and accurate initial alignment, streamlining the assembly process. This full-length grooving ensures maximum holding power and resistance to vibration and shear forces, crucial in demanding automotive environments.

Designed for Ease of Use:

Our Full Length Parallel Grooved Pins with Pilot are designed for efficient and straightforward assembly:

  • Pilot End for Easy Insertion: The pilot end allows for quick and accurate initial alignment of the pin and the mating components, simplifying the assembly process, especially in blind hole applications.
  • Press-Fit Installation: Installation requires only a simple hammer or press, eliminating the need for complex tooling or specialized skills.
  • Self-Retaining Mechanism: The grooved design creates a strong interference fit, ensuring the pin remains securely in place without the need for additional fasteners like cotter pins or washers in many applications.
  • Ease of Disassembly (if required): While providing a secure hold, these pins can be removed with appropriate tools if disassembly is necessary for maintenance or repair.

Key Advantages for Your Applications:

  • Precise Alignment: The pilot end ensures accurate positioning of connected components, vital for the functionality and longevity of automotive systems.
  • Strong and Reliable Fastening: The full-length parallel grooves provide maximum holding power and resistance to vibration, a common factor in automotive environments.
  • Simplified Assembly: The press-fit installation and pilot end reduce assembly time and complexity.
  • Cost-Effective Solution: Offers a durable and reliable fastening method without the need for additional hardware in many cases.
  • Versatile Applications: Suitable for a wide range of alignment and fastening tasks within the automotive industry.
  • Standardized Dimensions: Conforming to DIN 1470 and ISO 8740 ensures interchangeability and predictable performance.

Ideal for:
