Stainless steel equipment is fabricated to exhibit damage, defects, and surface-affecting substances such as dust, embedded iron powder, heat-tempered colors, oxidized layers, rust spots, abrasive burrs, weld stains, spatters, fluxes, weld imperfections, oils, greases, residual adhesives, paints, and markings.
Bolt: A mechanical part, cylindrical threaded fastener with nut. Consisting of a head and screw (cylinder with external threads), designed to be fitted with a nut for fastening two parts with through holes. This type of connection is called bolted connection - a detachable connection where parts can be separated by unscrewing the nut.
Bolts are indispensable in daily life and industrial production, often called "industrial meters" due to their wide usage:
| Automotive | In high-strength applications such as automotive engines, heavy-duty machinery, and bridge construction, preferred for larger support area and better 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 | For connecting power generation equipment and transmission lines in the energy industry. |
| Architectural | In construction engineering, shipbuilding, and petrochemical industry for connecting structures, improving navigation safety, and ensuring equipment stability. |
| Aluminum | Excellent thermal/electrical conductivity but naturally soft. Requires proper operation to avoid processing difficulties. |
| Titanium | Requires EDM machining with deionized water medium to control heat during processing. |
| Steel | Very strong metal that generates significant heat during processing, requiring special precautions. |
| Brass | High tensile strength, easy to machine but requires slow cutting speed due to softness. |
- Thicker bolt head provides resistance to deformation under vibration
- Flange design allows slight deformation for more secure locking
- Compact head design enables use in confined spaces
- Flange plate enhances fastening capability
- Flat washer design prevents material perforation in softer applications
