Square Head Bolts
Introduction to Square Head Bolts
Square head bolts, as the name implies, feature square-shaped heads and function well in applications that have limited accessibility. They are among the earliest fasteners used in construction and manufacturing, with roots going back to the early Industrial Revolution. The design allows for easy gripping with tools to facilitate smooth installation in hard-to-reach or challenging areas. The flat surface allows a wrench to connect and securely tighten while reducing slippage, even if the user cannot see the installation point.
Typically made from durable steel, these bolts are ideal for heavy-duty applications because they can withstand high levels of stress and wear. The bolts are available in full or partial coarse threads, as well as in diameters ranging from 1/4in. - 1in. and lengths ranging from 1-1/4 in. - 12 in. to accommodate a wide range of connection needs.

Square Head Bolts Compared to Other Bolts
The main design difference between square bolts and other bolts is the shape of the head; square heads provide a strong grip for wrenches in awkward or limited spacing. However, hex bolts, shoulder bolts, and similar fasteners all offer unique designs that make them suitable for different applications.
Using Square Head Bolts with Square Nuts and Washers
Square head bolts are sometimes used with square nuts to maintain a uniform look, but most of the time this is purely for aesthetics. Square washers are used when the application requires them, but generally, these fasteners are often used separately from each other.
