Taper Pins — Applications & Typical Uses

Taper Pins are used primarily for precise location and light shear duty between two parts. This page summarizes where they fit, the industries that rely on them, and the practical points to get right when you specify them — to ISO 2339 / DIN 1. Stocked across roughly M0.6 to M50, they cover general to heavy-duty work.

Typical Applications for Taper Pins

The most common settings where these are specified:

  • General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
  • Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
  • Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.
  • Jigs & fixtures: precise location of tooling plates and locating features.
  • Linkages & hinges: pivot points carrying light shear.

How to Specify Taper Pins for Your Application

  • Size: Match the nominal size to the mating thread or hole. This product spans M0.6–M50; check the full table below for the exact dimensions of each size.
  • Material: Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
  • Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
  • Standard: This product is supplied to ISO 2339 / DIN 1. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

Where Taper Pins Are Not the Right Choice

Not for carrying significant tensile or repeated heavy shear loads — use a bolt or a keyed joint for that.

Technical Drawing

Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Frequently Asked Questions

How do I choose the right size of Taper Pins?

Match the nominal size to the mating thread or hole. This product is available from M0.6 to M50; the full dimension table on this page lists each size.

What material should Taper Pins be for outdoor use?

For damp, coastal or chemical environments specify A4 (316) stainless or a suitably coated steel. For indoor or dry use, A2 (304) stainless or zinc-plated steel is normally adequate.

Are Taper Pins made to a recognized standard?

Yes — they are manufactured to ISO 2339 / DIN 1, so dimensions are interchangeable between suppliers when you quote the standard on your order.

What are Taper Pins used for?

Precise location and light shear duty between two parts. They are supplied to ISO 2339 / DIN 1.

Can I get a quote for Taper Pins in the size and material I need?

Yes. Use the technical drawing and quote form on this page to set the size and options, then send the exact configuration to our team for pricing and lead time.
