Square head bolts are fasteners with a round threaded shank and a square head that allows for more tightening than a hex head. A square head bolt is often made from various grades of steel, such as grade 5 and grade 8, and this grade is indicated with markings on the square screw head. The higher the grade, the more strength it has. Square headed bolts may also include a finish or coating for corrosion resistance. Stainless steel square head bolts offer the strength of their steel counterparts, while also providing resistance to corrosion. Some may be mildly magnetic. Tensile strength and hardness, as well as any specifications met, should be indicated for each fastener. Most square head bolts include head height and width, which can help determine tightening capacity. They may mate with square nuts or fit
into an existing mechanical system.
