Product Description
18-8 Metric Steel Polished Passivation Round Parallel Dowel Pins are essential commercial fasteners used for positioning and fastening mechanical parts. Available in cylindrical and conical types, these pins are installed using pressing methods or soft metal knocking techniques.
Key Applications
| Automotive | High-strength applications including automotive engines, heavy-duty machinery, and bridge construction, preferred for their larger support area and superior anti-loosening performance. |
| Mechanical | Used in mechanical, electronic, automotive, and construction fields to connect various mechanical parts, circuit boards, engines, transmissions, and building structures. |
| Energy | Connects power generation equipment and transmission lines in the energy industry. |
| Architectural | Used in construction engineering, shipbuilding, and petrochemical industries to connect building structures, improve ship navigation safety and stability, and ensure petrochemical equipment safety. |
Material Specifications
| Aluminum | Excellent thermal and electrical conductivity but naturally soft. Requires proper handling during processing to avoid difficulties in cutting. |
| Titanium | Well-suited for EDM machining but requires deionized water as a medium to control heat during processing. |
| Steel | Very strong metal often machined using wire cutting machines for complex features. Requires heat management during processing. |
| Brass | High tensile strength and easy to machine, but requires slow cutting speeds due to its soft nature. |
