12/10/2023 0 Comments Rivet bolt connectionsHowever, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft).įastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term rivet was introduced and, where they are remembered, are usually classified among nails and bolts respectively. To distinguish between the two ends of the rivet, the original head is called the factory head and the deformed end is called the shop head or buck-tail.īecause there is effectively a head on each end of an installed rivet, it can support tension loads. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. On installation, the rivet is placed in a punched or drilled hole, and the tail is upset or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. The end opposite the head is called the tail. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. Brown (December 2014).Ī rivet is a permanent mechanical fastener.

Learn more about their most common rivets below or download their conversion chart on their most common rivet selections. We’re proud to partner with Brighton-Best International, manufacturer of some of the world’s most reliable fasteners. Rivet guns are available in a variety of application styles including manual and cordless as well as hydraulic and pneumatic rivet guns. Solid rivets are ideal for use in permanent fastening applications and offer reliability, durability and strength.īack up rivet washers are to be used with blind rivets to create a larger surface area and prevent pull-through as it distributes force and pressure over a larger space. Pin-drive rivets are ideal when there is limited access to the joined parts and can be used in through-holes or closed-end holes. Multi-grip rivets offer flexibility in applications that require materials of various thickness or in rivets of multiple sizes. Otherwise known as POP rivets, these are ideal for use when there is limited or no access to the rear or blind side of the joined parts. We carry many different types of riveting tools and rivets for every need, including those made from steel, aluminum and stainless steel. In fact, choosing the wrong size for the application can lead to joint instability and failure.Ĭommon types of rivets include solid rivets, high strength structural steel rivets, blind rivets, drive rivets, countersunk rivets and flush rivets, but there are countless options to choose from. Cost and strength requirements are among the top considerations, but size does matter as well. No matter the job, there’s likely a rivet that can meet your needs. What are the most common types of rivets and rivet tools? That’s good news if you want a long-lasting joint that can resist vibration and be used in both high-tension and shear loads, but bad news if the joint needs to be disassembled for repair or replacement.Īdditionally, riveting may be the right solution for your mechanical fastening needs if you are unable to access the other side of the joined surface, otherwise known as the blind.ĬONTACT US TODAY TO DISCUSS YOUR NEEDS OR TO SCHEDULE AN ONSITE CONSULTATION AT 31 OPTION 4. The downside is that it cannot be easily disassembled and must be drilled out to remove. The benefit of using a rivet is that it creates a strong and reliable joint even in high vibratory conditions. To break the connection point of a rivet, it must be damaged and cannot be reused. While both types of fastening systems can offer strong connection points, rivets are designed for permanent or semi-permanent joints whereas bolts can be unscrewed and then reassembled. If you break it down, the function of a rivet is very similar to that of a nut and bolt, with a few exceptions. At-home applications like door and ceiling installationĪre rivets better than bolts in your joint assembly?.Residential and commercial construction.Today, they are used in a variety of projects including: In the past, rivets were used primarily in heavy industrial fastening applications.
