A Square-Head Bolt is a fastener used to secure two or more pieces of material together. It has a square head that is designed to mate with a corresponding square-shaped hole in the material being connected. The bolt is then tightened, which pulls the material together and creates a firm connection.

Square-head bolts can be used in large-scale applications, from general construction to electrical work.
One of the most common uses for square-head bolts is as an anchor point in concrete. 
The large surface area of the head helps to distribute the weight of the load, making it less likely to pull out. 
Square-head bolts are also often used in machinery and heavy equipment, where they can help to secure moving parts.

Until the early 20th century, square bolts were commonly used in a variety of applications. These bolts consist of a head with foursquare corners and a body that is also square in cross-section. Square bolts are easy to manufacture and provide a high degree of strength and resistance to shearing forces. However, they are also more likely to loosen over time due to the increased surface area of the square head. For this reason, hexagonal bolts became increasingly popular for use in high-stress applications. Square bolts are still used in some applications where their resistance to shearing forces is valuable, but they are no longer as common as they once were.

In addition to bolts, we also supply a variety of other fasteners. We have a wide selection of nuts, screws, washers, and rivets in a variety of sizes and materials. Whether you’re looking for something to hold together metal plates or secure a wood panel to a wall, we have the perfect fastener for the job. Our knowledgeable staff can help you choose the right product for your needs. So come on down and take a look at our selection today!

In addition to the standard bolts that we manufacture, we also offer hook bolts, rod end bolts, flange bolts, etc. Hook bolts are designed for use in applications where a traditional bolt would not be able to provide a secure hold. They are commonly used in construction and heavy engineering. Rod end bolts are used to connect rod ends to clevises, yokes, and other similar fittings. They are typically made from high-strength materials such as steel or titanium. Flange bolts are used to connect two flanges together. They are available in a variety of sizes and finishes, making them suitable for use in a wide range of applications.
