Round head bolts with square neck are essential components in many industries, especially in constructions and carpentry. Their unique shape and functionality make them ideal for several applications, providing a secure and reliable connection between materials. In this section, we will review the characteristics of these bolts, their development, technological innovations, current applications and a few examples of their practical use.

Background and development

The use of bolts and other fasteners dates back hundreds of years. However, DIN 603, ISO 8677 and UNI 5731 bolts, also known as round head bolts with square neck, are more recent. These bolts were designed in order to achieve greater stability and security in connections, especially in constructions and wood processing. Its square neck prevents the bolt from turning when tightening the nut, ensuring a firm and secure grip.

Technological evolution

Over the years, round head bolts with square neck have taken advantage from significant technological innovations. Today, they are manufactured from high-quality materials such as stainless steel and high-strength alloys, which offer greater durability and corrosion resistance. In addition, modern manufacturing techniques ensure more precise threads, further improving the security of joints and making them tighter.

Surface treatment technologies, such as zinc and nickel plating, offer additional benefits in terms of weather and chemical resistance, making these bolts ideal for both indoor and outdoor applications.

Modern applications

Round head bolts with square neck are used in a wide range of modern applications. Their ability to withstand mechanical stress makes them ideal to be used in the construction industry to assemble wooden structures, such as beams and panels. Moreover, they are also used in window and door frames, furniture manufacturing, gates, sheet metal products, streetscapes, benches, fences, gates and road guardrails. Their round head is less invasive than other shapes, thus reducing the risk of damaging surrounding materials and improving the aesthetics of the end result. In addition, its little protrusion, with no recess, notches nor edges on its head, makes this type of bolt especially suitable for anti-loosening functions.

In carpentry, these bolts are especially popular for the manufacturing of furniture and decorative structures. Its square neck ensures greater stability during assembly, making it easier to align parts precisely. In addition, its round head enables a clean finish, without sharp edges that could spoil the appearance of the wood.
