This bolt consists of three parts: a hexagonal head, a flange face, and a shank. The hexagonal head and flange face are integrally formed, with the flange face providing enhanced support, while the shank is used to connect the fastened components. This unique design results in a larger "ratio of support area to stress area" for the hex flange step bolt compared to standard hexagonal head bolts, enabling it to withstand higher preload forces and offering superior anti-loosening performance.

| Aluminum | Excellent thermal/electrical conductivity but naturally soft. May produce gelatinous buildup during processing. |
| Titanium | EDM machining recommended. Requires deionized water to control heat during processing. |
| Steel | Very strong metal. Wire cutting machines often preferred for complex features. Requires heat management. |
| Brass | High tensile strength, easy to machine but requires slow cutting speed due to softness. |
- Reusable medium carbon steel construction
- Easy installation and disassembly
- Time-Saving: Eliminates the need for additional washers, streamlining assembly
- Improved Joint Integrity: Maintains consistent preload, reducing joint failure risks.
- Durable wholeness
