Will the positioning pin rust?

Products without surface treatment will rust. It is recommended to regularly apply antirust oil for maintenance or choose products with surface treatment (no-electro nickel plated), which can prevent rust in normal atmospheric environments. No-electro nickel plated surface can effectively prevent rust.

What tools are suitable for measurement of positioning pin outer diameter?

If the outer diameter tolerance of the positioning pin is within 0.02mm, common vernier calipers and other measuring tools with general accuracy are not suitable. It is recommended to use a high accuracy external plug gauge or an internal micrometer for measurement.

Will the outer diameter of the positioning pin become smaller after installation?

It will become smaller, and m6 will shrink more than p6 after installation, so please pay attention during hole machining. For detailed change values, please refer to the precautions: change in inner diameter of the fixture bushing during press-fit.

What are the options for positioning pin outer diameter tolerance?

Optional tolerances for the outer diameter of positioning pin: m6, p6, m7, g7. Basically it can meet the needs of installation and positioning under general conditions.

What fixture bushings are commonly used together with positioning pins?

The fixture bushing is of basic shape, which is usually suitable for supporting positioning pins, checking insertion pins for fixtures, etc.
