Square head bolts were the fasteners of choice before hex head bolts came along, but they are still used for a variety of applications. Threaded bolts from Agri Supply come in many different styles because we believe in carrying something for everyone. We have threaded fasteners of different strengths, lengths and head types. We have 307a bolts, for instance, made of low carbon steel for low-pressure and normal temperature applications.
Square head bolts are used in period-faithful restoration work of old homes or machines. These threaded bolts are also good for dark or cramped spaces because it is easy to get a tool on the angled corners of their heads. These threaded fasteners are popular because they don’t require special hex-headed tool; you can turn them with a pliers. We have the fasteners you need for whatever project you are tackling.
