Harbor Freight Dowel Pins

Description:

1. The positioning pin should be selected as a standard part, and there are many kinds of positioning pins to choose from.
2. The hole for installing the positioning pin needs to be reamed with a reamer, and there is a reamer matching the positioning pin.
3. The strength of the positioning pin should be smaller than the strength of the parts to be positioned. In this way, when a large shear force occurs, only the positioning pin is damaged, not the parts are damaged. At best, change the positioning pin.
4. All the parts should be installed (or debugged) to the best state and fastened, then the hole can be drilled.
5. If high-strength positioning pins are used, the loss of damaged parts will be large in the event of an accident.

Common metal materials used in Dowel Pins manufacturing include:

Aluminum, lightweight, ductile, conductive and very resistant to oxidation.
Brass is strong, ductile, conductive, corrosion-resistant, and has low magnetic permeability.
Stainless steel is high pressure rated and chemically resistant.
Hardened and ground steel is compacted to produce a very hard but brittle metal. It goes through a hardening process such as quenching or induction. Unhardened steel is more ductile, but still suitable for many applications.
Titanium is strong and has good temperature and corrosion resistance. It is 44% lighter than steel.
