A hexagon head bolt is a threaded fastener featuring a six-sided external hexagonal head and a threaded shaft. It is commonly installed together with a nut and washer to create a strong and removable mechanical connection.
The hexagonal head design allows easy tightening and removal using standard tools such as wrenches and torque tools. Compared with other bolt head designs, hex bolts provide higher installation efficiency and better torque control.
Hexagon head bolts are available in both:
Metric Hex Bolts (M thread system)
Imperial Hex Bolts (UNC / UNF thread system)
Common materials include:
Carbon Steel
Alloy Steel
Stainless Steel 304 / 316
High Strength Steel
Typical strength grades include:
Grade 5 Hex Bolts
Grade 8 Hex Bolts
Grade 9 Heavy Duty Hex Bolts
ISO 898-1 Class 8.8 / 10.9 / 12.9 Bolts
Industrial hex bolts are designed to withstand high tensile loads and shear forces. Their robust structure ensures reliable fastening performance in heavy-duty applications.
