Double Hole Dowel Pin

Double hole dowel pins are headless locating pins featuring cross-holes on both ends, designed for applications that require securing with cotter pins, retaining clips, or locking mechanisms.

Commonly used in molds, jigs, and machine components, these pins support quick positioning, anti-loosening functionality, and improved assembly and maintenance efficiency.

Available in carbon steel or stainless steel, these pins can be customized in terms of tolerances, inner hole dimensions, chamfering, and stop features. They can also be paired with R-clips or safety rings based on application needs.
