Want to know about Types of rivets?
Then you landed in the right place. Here you will get a complete guide on types of rivets and their uses, from scratch to end.
⇒Here are some basics of Rivets, Have a look first-
Rivets are fasteners used for joining metal sheets and plates in fabrication work such as bridges, ships, cranes, structural steelwork, boilers, aircraft etc.
The rivet is often inserted and close by force so that it completely fills the holes and forms rigid rivets joint.
And, Riveting is the method of making permanent joints for riveting the plates to be joined are drilled or punched.
Now, let’s dig into the mainstream of the article, Where you will know types of rivets with diagram–
Types of Rivets-
Here are the most common 11 types of rivets-
- Solid rivets
- Split rivets
- Blind rivets
- Tubular rivets
- Snap head rivets
- Pan head rivets
- Mushroom head rivets
- Countersunk rivets
- Conical head rivets
- Pan head with tapered neck rivets
Solid rivet’s shank is solid and is used for general purposes. This rivet is the strongest of all kinds.
It is the simplest and reliable rivet founded in the Bronze age and can be fitted through a hammer or rivet gun.
The material used in manufacturing can be aluminium, brass, copper, stainless steel etc and comes in many colours and sizes.
Split’s shank is divided into parts and identified by pairs of legs on their tails which are folded back on themselves after installation.
it is used in small and light works like tin plates, textiles, leather, plastics and use in bicycle seats.
As the name suggests, It is split into two parts from the body side and has a single head at the top. It is also known as a Bifurcated rivet.
As the name suggests, Blind rivets are actually used where you can not access the other side of the surface like something hollow.
Metal sheets and other hard materials are fastening through blind rivets with the help of the rivet-gun.
The common uses of these rivets refer to brittle and soft materials, electrical parts, automobiles, hand tools, locks, and home appliances etc.
Commonly, It is also known as POP and Break stem rivet.
Tubular’s shank is hollow in nature and the rest is just similar to the solid rivet. It is used to drill in shoes and file covers etc.
This can also be used to fasten aluminium, thin metals sheets, plastics, leather and on the pivot points where movement is required.
This is also known as Hollow rivet, due to the hollow shape at the body end.
This is classified into two categories-
(I) Full Tubular
(II) Semi Tubular
Snap Head Rivet-
Snap head or cup head rivet is the most commonly used rivet and it gives a very strong joint.
These rivets are widely used and meet the requirement of various industries like the manufacturing and construction industries to provide maximum strength in general.
The diameter of Shank is approx 1.6d and the length of the head is 0.7d.
Pan Head Rivet-
It has the unique design of a slightly rounded head and slopping down from the top of the head(see diagram) to provide a tighter grip during the fastening process.
This can be made up of carbon steel, brass, copper, aluminium and stainless steel with a length range from 6mm to 100mm in general.
Pan heads are used in Heavy structural work to provide maximum strength and grip.
Mushroom Head Rivets-
A mushroom head is used to deduce the rivet head height on the metal surface and provides the locking needed for maximum strength.
As the name suggests, these rivets are mushroom-like heads and have a lower profile than standard rivets.
Materials are used to manufacture these rivets aluminium alloys, titanium, and nickel alloys.
Countersunk head rivets are used where the top surface of the plate is required to be free from projecting rivet heads.
It is used in countersunk or dimpled holes and mostly in aircraft for aerodynamic flexibilities. It is also known as the Flush rivet.
These rivets are three types, based on their neck angle-
(I) 120° Shank
(II) 90° Shank
(III) 60° Shank
Round, flat and solid cylindrical in design, is perfectly suitable for fastening joints, rotating parts and other industrial needs.
This requires less force to penetrate than solid rivets. This is also known as a slotted rivet.
Conical Head Rivet-
This rivet comes with a little bit of complex design having a neck angle of 60° with 0.125d of length from neck to bottom(Shank) including a head height of 0.8d.
Pan Head with Tapered Neck Rivet-
This has a head height of 0.7d or top tampered area diameter is 1.6d with 15° of the neck angle.
Applications of Rivets-
Here are some applications and rivets use-
- Structural Work
- Power Plants
- Aero Engineering
- For Vibration Reduction
