This assists in achieving correct shear and tensile strength whilst ensuring the longevity of the rivet. Best practice dictates that the middle grip range of a rivet should be used and not the minimum/maximum sizes. ![]() For example, if two 1.5 mm plates/items need to be riveted, a blind rivet with a material grip range between 2- 5 mm is required. The material grip range refers to the material thickness or the depth the rivet can be effectively installed. ![]() Refer to the table below covering diameters and corresponding hole sizes. Referring to the hole diameters before drilling is an easy way to avoid issues later. If the rivets diameter is too small for its hole the fastener will fail. The larger the diameter the stronger the rivet. Rivet diameter selection is guided by the material gauge, for instance use small diameter rivets with lightweight fascia covers and larger diameter rivets in the fabrication of checker plate tool boxes. When reviewing material, you will also need to consider environmental factors, such as extreme temperatures or salt sprays. Stainless with stainless, aluminium with aluminium, etc. ![]() Avoid using aluminium and stainless steel together, we recommend keeping the metal material like for like for maximum life. Use steel rivets for heavy duty applications and aluminium rivets for lightweight jobs.Įnsure the rivet material is compatible with the material being joined to minimise galvanic corrosion. As a general rule an aluminium body with aluminium pin is not very strong aluminium body with steel pin are a a little stronger steel body with steel pin are stronger still and stainless-steel body with either steel or stainless-steel pin are the strongest. Rivet material type provide a good guide to their strength. These fasteners typically come in steel, stainless steel (304 & 316 grade stainless steel), or aluminum or in a combination of these materials. For example, you will read “aluminum/steel”, which means an aluminum body with a steel pin. The rivet is categorised by the material of the body and then the material of the pin. Now lets consider rivet material, rivet diameter size, and thickness of the material you are riveting. Rivet selection is a little easier after you have settled on the right rivet type. There are numerous rivetlabels for the same rivet type and in this blog we have incorporated the different descriptions into the title. Your rivet selection criteria should be based on the application connection you believe is required, whether your job involves installing lightweight guttering & fascias or heavy duty truck fabrication. Blind pop rivets are the most common style of rivet on the market. Here we list the different types of blind rivet sub-categories plus some specialised industrial strength structural rivets. There are many other different types of rivets like semi-tubular, split rivets, and solid rivets however in this blog we are reviewing blind rivets.
