Square Head Bolt

These bolts are commonly used in applications where traditional hex head bolts might be difficult to install or where a secure, high-torque connection is needed. Square head bolts are utilized in applications where strong fastening is needed but visibility is restricted. These bolts are simple to tighten with a wrench and have large, flat sides. Square heads work best in small, dim areas where a fabricator or machinist must blindly tighten the bolt. Even without any visible marks, it is easy to fit a tool across the square head, reducing the likelihood of tool slippage. The square head provides a larger surface area for gripping with a wrench, making it easier to install and tighten, even in difficult-to-reach areas.
