Square head bolts (square head screws) are essential fasteners across industries. Their defining feature is the square - shaped head, which delivers practical advantages. Material - wise, they can be fabricated from diverse metals; stainless steel variants (such as 18 - 8 (A2), A4, SUS304, SUS316, SUS316L) are highly favored for their superior corrosion resistance, enabling use in harsh settings like marine or chemical facilities. In coastal regions with high saltwater exposure, these bolts withstand corrosion and retain structural integrity. The square - head geometry enables straightforward manual tightening/loosening via wrenches or sockets. Unlike round - headed bolts that may slip under torque, the flat square - head surface ensures a stable grip, simplifying installation and maintenance—especially in confined spaces or when power tools are inaccessible. Available in sizes like M2, M8, M12, M16 and strength ratings (e.g., A2 - 70, A2 - 80, A4 - 70, A4 - 80), they meet specific load demands. High - strength square head bolts are frequently employed in structural applications (e.g., buildingames, heavy fr- machinery assembly) to guarantee structural stability and safety.
| 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. |
