Pin Shafts

Precision pins and short shafts for pivots, locating features, and light-duty drive links. Ground or turned to tight diameter and length tolerances for jigs, fixtures, linkages, and small mechanisms in CNC and automation work.

Pin Shafts

Overview

•

Dowel, pivot, and clevis-style pin shafts

•

Diameter and roundness suited to press or slip fits

•

Chamfers, grooves, and cross-holes as specified

•

Through harden or case harden when wear matters

•

Fast cycles for fixture and automation spares

Frequently Asked Questions

What is a pin shaft?

A pin shaft is a short, usually cylindrical shaft used as a pivot, locator, or light-duty drive element. It may include shoulders, grooves, or cross-holes for retention.

Press fit or slip fit—what should I choose?

Press fits locate permanently; slip or close-running fits suit pivots. Share the mating hole and we recommend diameter tolerance and finish.

Can pins be hardened?

Yes. We through-harden or case-harden common steels and can grind after heat treat to restore diameter.

Do you make custom lengths from standard stock?

Often yes—cut, chamfer, and finish grind from precision bar or tube when it meets your grade and diameter.

Minimum order quantity?

Prototypes from a handful of pieces; production from dozens to thousands. Swiss turning keeps unit cost low as quantity rises.
