Precision Cylinder Pin

A precision cylinder pin, commonly referred to as a dowel pin, is a type of fastener that is primarily used to locate components with respect to each other and to maintain an accurate alignment between them. These pins are cylindrical and are precisely machined to have tight tolerances, making them essential in high-precision engineering applications.

Precision Cylinder Pin Standards and Specifications

DIN 6325: A widely recognized international standard for precision dowel pins that specifies dimensions, tolerances, and material properties, including diameter and length tolerances such as H6 or H7.

ANSI/ASME B18.8.2: An American standard detailing dimensions and tolerances for dowel pins, ensuring uniformity and compatibility in North American applications. It covers different pin types and their specific measurements.

ISO 2338: An international standard that outlines the dimensions and tolerances for dowel pins, ensuring global consistency and interchangeability in precision applications.

Materials and Finishes: Precision cylinder pins are typically made from high-carbon steel, stainless steel, or other durable alloys. They may undergo surface treatments like coating or grinding to enhance properties such as corrosion resistance and smoothness.

Tolerance Classes: Tolerance classes, such as H6 and H7, indicate the precision of the pins. For example, H7 provides a tighter tolerance compared to H6, ensuring higher accuracy for demanding applications.
