Steel, stainless steel, and brass hex head screws

Hex head screws provide a reliable solution for strong and secure fastenings, and are therefore widely used in industries such as mechanics, construction, and plant engineering. The hexagonal head allows for quick and precise installation with standard tools, offering high tensile and shear strength.
