Product Description

The Φ3.5x5 dowel pins and Φ3.5x5 spring pins are precision-engineered metric components designed for secure alignment and assembly in industrial applications. These cylindrical fasteners feature a nominal diameter of 3.5mm and a length of 5mm, manufactured to tight tolerances for consistent performance. The dowel pins provide rigid positioning in machinery, automotive systems, and electronic enclosures, while the spring pins offer flexibility for vibration-resistant connections. Constructed from hardened steel with optional corrosion-resistant coatings, both variants operate in temperatures ranging from -30°C to +120°C. Their compact metric sizing ensures compatibility with standard mounting interfaces, though installation requires precise bore alignment. Primary applications include CNC equipment, automation systems, and precision tooling assemblies where reliable component registration is critical. Key advantages include high shear strength, repeatable accuracy, and minimal maintenance requirements, though permanent installation limits reusability.
