Spring (Roll) Pin — ISO / DIN (Series 103) 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 / DIN. Stocked across roughly M2 to M16, they cover general to heavy-duty work.
Typical Applications for Spring (Roll) Pin — ISO / DIN (Series 103)
The most common settings where these are specified:
- Machine alignment: dowelling mating housings so they reassemble in the same position.
- 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.
How to Specify Spring (Roll) Pin — ISO / DIN (Series 103) for Your Application
- Size: Match the nominal size to the mating thread or hole. This product spans M2–M16; 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 / DIN. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Where Spring (Roll) Pin — ISO / DIN (Series 103) Are Not the Right Choice
Not for carrying significant tensile or repeated heavy shear loads — use a bolt or a keyed joint for that.
