Metal Nuts

Hex Nuts

Hex and square standard nuts are primary internally threaded fasteners designed to mate with external machine threads to create secure structural joints. Hex nuts feature a six-sided profile that allows for efficient 60-degree wrench rotation, maximizing accessibility in confined spaces across general assembly applications. Conversely, four-sided square nuts offer an increased surface bearing area and higher resistance to rotational loosening, making them optimal for heavy-duty structural steel, railway infrastructure, and blind-location installations.
