Product Description

In the 1830’s, square headed bolts were superseded by the hex head. The widespread use of hex head nuts and bolts came about due to innovation in engineering and metallurgy. Hex head nuts and bolts and the tools to use them require close tolerances, whilst square heads required less accurate tolerances.

Square headed bolts were commonly used in early applications. When machinists used cast iron and cruder forms of steel, square bolt heads were easier to make with the tools, metals and techniques of the time. As machinery became smaller and more compact, however, the hex head evolved to meet the need for more compact bolt heads.

To complement our range of fixtures and fittings, we have sourced a range of vintage style industrial black oxide square headed bolts. They available in variety of sizes and lengths to suit various applications such as furniture construction, woodworking projects, lighting design and any general vintage industrial project.
