Parallel Pins with Internal Thread DIN 7979 ISO 8735 Cylindrical spindles Dowel Pins for auto parts fastener

Our DIN 7979 Parallel Pins with Internal Thread offer a reliable and straightforward solution for precise alignment and secure joining in various automotive assemblies. The internal thread allows for easy extraction using a puller screw, simplifying maintenance and disassembly processes.

Key Advantages for Your Automotive Applications:

• Precise Alignment: Manufactured to DIN 7979 standards, these parallel pins ensure accurate positioning and alignment of components, crucial for the precise operation of automotive systems. The tight tolerances guarantee a snug fit, minimizing play and ensuring the integrity of the assembly.
• Simplified Disassembly: The integrated internal thread enables easy and damage-free extraction using a standard puller screw. This significantly reduces downtime during maintenance, repair, or component replacement in automotive manufacturing and service environments.
• Secure Joining: When used in conjunction with interference fits, these parallel pins provide a strong and durable connection between automotive parts, capable of withstanding the vibrations and stresses encountered in vehicle operation.
• Versatile Application: Suitable for a wide range of materials commonly used in the automotive industry, including steel, aluminum, and various alloys. The availability in different sizes (e.g., diameter 6mm to 12mm and lengths up to 80mm, as seen in the reference) allows for adaptation to diverse assembly requirements.
• Durable Materials: Typically manufactured from high-quality steel, often hardened (e.g., HRC 60 ±2 as per the reference) to ensure resistance to wear, shear forces, and deformation, contributing to the long-term reliability of automotive assemblies.
• Cost-Effective Solution: Parallel pins offer a simple yet effective joining method, providing a cost-efficient alternative to more complex fastening solutions in many automotive applications.

Ideal for Automotive Applications Such As:

• Alignment of Transmission Components: Ensuring precise alignment of gears, shafts, and other critical components within automotive transmissions for smooth and efficient power transfer.
• Locating Engine Parts: Accurately positioning engine components like cylinder heads, manifolds, and brackets during assembly.
• Securing Suspension Elements: Providing precise alignment and secure connections for certain non-critical elements within the suspension system.
• Indexing and Positioning in Fixtures: Used in automotive manufacturing jigs and fixtures for accurate workpiece positioning during welding, machining, or assembly processes.
• Dowel Pins for Mold Alignment: Ensuring precise alignment of mold halves in the production of plastic and composite automotive interior and exterior parts.
• General Purpose Alignment and Joining: Suitable for various other alignment and joining tasks in automotive sub-assemblies where ease of disassembly is a consideration.
