Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100) 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 GB/T 120.1 / ISO 8735. Stocked across roughly M4 to M20, they cover general to heavy-duty work.
Typical Applications for Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100)
The most common settings where these are specified:
- Jigs & fixtures: precise location of tooling plates and locating features.
- Linkages & hinges: pivot points carrying light shear.
- 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.
How to Specify Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100) for Your Application
- Size: Match the nominal size to the mating thread or hole. This product spans M4–M20; 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 GB/T 120.1 / ISO 8735. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Where Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100) Are Not the Right Choice
Not for carrying significant tensile or repeated heavy shear loads — use a bolt or a keyed joint for that.
