THE BLIND RIVET, A FASTENING ELEMENT WHICH MAKES THE ASSEMBLIES PERMANENT
A blind rivet is a fastener used to join materials together permanently. At Würth, we have designed a wide range of blind rivets for professionals: split, fluted, petal, structural… This article will tell you a little more about their characteristics.
HOW DOES A BLIND RIVET WORK?
A blind rivet bears this name because it can be fixed ""blind"", that is to say without having access to one of the two sides of the assembly. It is made up of two parts: the body (a hollow tube with a head, also called a collar) and the nail (a rod responsible for deforming the body during crimping). To perform riveting:
• take a riveting pliers
• pull on the nail using the latter
• the swollen part of the nail will then enter the body ...
• … Until the nail breaks, leaving the rivet alone and perfectly fixed (hence the alternative name of ""break-rod rivet"").
DETERMINE THE RIVET TO USE: ALUMINUM OR STAINLESS STEEL, LARGE OR COUNTERSUNK HEAD, ETC.
• Are you looking to identify the most suitable blind rivets for your project? Remember that there are several parameters to consider, namely:
• the material of the nail (aluminum, steel, stainless steel, copper, etc.), which depends on the load to be supported and the material of the part to be crimped, to reduce the risk of corrosion
• the head of the rivet (classic flat head for hard materials, large head reserved for softer materials, countersunk head for an impeccable finish, etc.)
• the diameter of the rivet body, which should match the diameter of the hole minus 0.2mm
• the thickness of the part to be crossed, knowing that the rivet must not be too short, but must not exceed
• and of course the type of rivet, as we will see in the next paragraph.
FLUTED, EXPLODED, PETAL BLIND RIVET ... DISCOVER OUR DIFFERENT MODELS
At Würth, we have designed multiple models of blind rivets, adapted to all the needs encountered by professionals who have to perform riveting. Visit our online store and you will find rivets with various bodies:
• structural blind rivets, used for parts subjected to strong vibrations and high shear stresses, perfect for making hyper-resistant assemblies, for example for machines or truck bodies
• fluted blind rivets, with a body traversed by flutes which facilitate their fixing in wood or plastic
• burst blind rivets, which open in four parts, lose their head during installation and are intended for fragile materials
• petal blind rivets, quite similar to the previous ones but which retain their head during crimping and whose opening takes the form of three petals, etc.
