Types of rivets

When working with metal structures or mechanisms, one inevitably encounters the issue of fasteners. While there is a wide variety of fastening technologies and materials, only a few basic ones are used in everyday life. Retail store, wholesale warehouse of fasteners Krepkom offers competitive prices on a wide variety of fasteners and components. In addition to its wide selection, the company also offers competitive prices.

Types of fasteners and choosing the optimal solution

All types of connections can be divided into two types: detachable and non-detachable. The former includes all fasteners that can be repeatedly assembled and disassembled without damage. The latter group includes so-called "blind" or permanent connections, such as welding, soldering, and riveting. You can learn more about all the different types of fastening technologies by at least occasionally looking at news from the world of fasteners.

While welding and soldering largely depend solely on the quality of the electrodes/welding material and the skill of the worker performing the work, rivets are a slightly different matter. There is a wide variety of rivet products, and they can be divided into three main groups:

• With a solid rod – high strength, tightness, but difficult to install;
• Semi-hollow – the stem is solid near the insert head and hollow near the closing head. They are easy to install, maintain a tight seal, and bear less load;
• Hollow - the entire rod is hollow, easy to install but cannot provide a tight seal or high strength connection.

According to the type of head, they are also bottled as:

• Semicircular (spherical/high/low) are the most durable and dense;
• Cylindrical and conical;
• Hidden and semi-hidden.

Rivets also differ in the materials they are made from, with various alloys and plastics available. All rivets are similar in their clamping principle, but some models operate not by clamping sheets of material together with two heads, but by friction and the effect of "biting notches" into fibrous material (knurled rivets). There is also a wide range of expansion and petal rivets, designed for fastening loose or soft materials. It's best to choose the best option in-store, consulting with experienced salespeople, such as those at Krepkiy.
