DOWEL PIN

A DOWEL PIN is a precision shaft-like component used for part alignment, maintaining relative position, and carrying shear loads. It is installed into mating holes between two or more workpieces to improve assembly accuracy and allow components to be reassembled in their original position after disassembly.

Improves Assembly Accuracy

A DOWEL PIN can restrict lateral movement and rotation of the workpiece, helping components align accurately in their intended positions.

Maintains Repeatable Positioning

After equipment disassembly, maintenance, or component replacement, the original dowel holes can be used to restore the components to their previous positions, reducing the time required for realignment.

Helps Carry Transverse Shear Loads

A DOWEL PIN can carry part of the lateral load acting across the joint surface, reducing the amount of shear force that must be carried entirely by screws or bolts.

Multiple Structural Options Available

Depending on assembly requirements, cylindrical dowel pins, tapered pins, shouldered pins, threaded locating pins, or custom-designed configurations can be selected.

Suitable for Precision Equipment

DOWEL PINS are commonly used in molds, jigs and fixtures, automation equipment, machinery, automotive and motorcycle components, electronic equipment, and precision instruments.
