What is a DIN 7 Dowel Pin?
DIN 7 defines cylindrical parallel dowel pins as standard fasteners used to ensure accurate positioning and alignment of two or more components.
DIN 7 cylindrical parallel dowel pins are generally made of hardened steel and are a solid cylindrical bar. It has a smooth appearance, high surface hardness, is wear-resistant and can withstand shear forces without deformation. It is used for precise connections between two or more parts.
Characteristics:
- Uniform cylindrical shape
- Precise diameter and length
- Press-fit installation
- High positional accuracy
