Square head bolts (square head screws) are widely adopted fasteners in industries and construction projects. Their key feature is the square - shaped head, which brings multiple benefits. In terms of material, they can be made from various metals, and stainless steel (e.g., 18 - 8 (A2), A4, SUS304, SUS316, SUS316L) is a popular option. This material offers excellent corrosion resistance, making them suitable for harsh environments like marine or chemical plants. For example, in coastal areas with abundant saltwater, these bolts can resist corrosion and maintain their integrity over time. The square - head design allows for easy manual tightening or loosening with a wrench or socket. Unlike some round - headed bolts that may slip under torque, the flat surface of the square head provides a stable grip, facilitating installation and maintenance, especially in tight spaces or where power tools are not readily available. Square head bolts come in different sizes (e.g., M2, M8, M12, M16) and strength grades (e.g., A2 - 70, A2 - 80, A4 - 70, A4 - 80) to meet specific load - bearing requirements. High - strength square head bolts are often used in structural applications, such as building frameworks or heavy - machinery assembly, to ensure the stability and safety of the structure.
| 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. |
