If have any doubt you can ask us in comments. I hope you like our article on “ types of rivets and riveted joint“, if yes then please share with your friends.

Leakage can be a problem for these types of joints but is overcome by special techniques.

It requires skilled workers to do the riveting process.Disadvantages of Rivet Jointsįollowing are the disadvantages of rivet joints: The operation of the riveting process is easy.The riveting process requires low maintenance cost.Dissimilar metals can also be added, even non-metallic joints are also done with riveted joints.The fabrication cost of the riveting process is cheaper.Advantages of Rivet jointsįollowing are the advantages of rivet joints: Rivets are also used in heavy vehicles like buses and trucks.The rivet joints are applied in Boiler shells.

Rivets are also very useful in Railway wagons and coaches.

Rivet joints are applicable in structure members and also used in bridge parts to handle the strong loads.

If the diameter of the rivet is, d = 24 to 48 mm, then Clearance is taken as, C = 2 mm Application of Rivet Jointsįollowing are the application of rivet joints:.

If the diameter of the rivet is, d = 12 to 24 mm, then Clearance is taken as, C = 1.5 mm.

Normally clearance is considered as per the following: Clearance is noted when riveting because the diameter of the rivet increases to some extent by pressing. To join the riveting parts, they are drilled with the help of a drilling machine. In this process, the rivet’s tail is transformed into a ‘head’ sometimes called a ‘shop head’. The open ended body allows for more flexibility by not limiting the length of the fastener that can be used. Both styles provide spinout resistance when torque is applied from tightening or loosening threaded fasteners. The equal and opposite force distorts the rivet and the tail section of the rivet is turned to head downwards, so the entire rivet sits on the plates. What are the common types of rivet nuts The most common rivet nut styles include knurled and hex open ended bodies. Riveting is carried out with the help of dies and backup dies that place a rivet in between them and, by the use of force, the rivet is set into parts to join. Rivets can be found in various sizes ranging from about 5mm to 19mm (0.2 in. They are used for securing a wide range of materials from steel and aluminum to leather, denim, canvas, etc. Usually, this type of joint will be found in the butt joints. They are made of brass, copper, steel and aluminum. Where d is the diameter of the rivet hole.As you have seen in the above figure, here the rivets are arranged in rows that are wide at the ends of the butt and taper at opposite sides which give the diamond shape of considerable size. It is denoted by m.Ī joint may fail due to the tearing of the plate at an edge.Īnd this can be avoided by keeping the margin, m = 1.5d,

Margin or marginal pitch: It is the distance between the centres of rivet hole to the nearest edge of the plate.

Diagonal pitch: It is the distance between the centers of the rivets in adjacent rows of zigzag riveted joints.

Back pitch: It is the perpendicular distance between the centre lines of the successive rows.

Pitch: It is the distance from the centre of one rivet to the centre of the next rivet measured parallel to the seam.

In addition to above, depending on the number of rows of the rivets They are classified as single riveted joint, Double riveted, triple, quadruple and chain riveted joints.

In a double strap butt joint, the edges of the main plates are placed against each other and two cover plates are placed on both sides of the main plates and then riveted together.
