A rivet is a permanent mechanical fastener best suited for supporting shear loads. The most common type of rivet is called a blind (Pop or open-end) rivet. Blind rivets are used to join materials when you only have access to one side. They consist of a rivet and a mandrel, and require a setting tool for installation. Domed heads are suitable for most applications and provide a low profile and clean, finished appearance. Wide domed heads provide a larger head for extra holding strength for oversized holes or soft, thin materials. Countersunk blind rivets have an angled head and sit flush when installed.
Rivet and Mandrel Material & Corrosive Resistance
Stainless steel rivets and mandrels may be mildly magnetic and offer superior corrosion resistance. Aluminum rivets and mandrels and non-magnetic and are corrosion resistant. Aluminum/aluminum rivets have the lowest tensile and shear values of all break mandrel rivets. They should be used only when fastening materials with similar properties. Zinc plated rivets with steel mandrels have good rust resistance. The steel/steel style gives this rivet greater tensile and shear values compared to all aluminum rivet varieties. The all steel rivet should be used when fastening materials similar to carbon steel. Aluminum rivets with steel mandrels are corrosion resistant and non-magnetic. The steel mandrel gives this style rivet greater tensile strength and shear values than aluminum rivets with aluminum mandrels.
AFT carries a large variety of rivets, though only a few are displayed on the site. Additional styles include: full and semi-tubular rivets, solid rivets, drive pin rivets, and multi-grip rivets.
