Blind rivets are used for fastening materials together without access to or seeing the back of the material being riveted. They are constructed with a mandrel through the center that breaks off after insertion into a hole with a rivet tool. The rivet tool pulls the mandrel into the rivet, which expands the blind end of the rivet, and then snaps off. Blind rivets can be used as an alternative to spot welding. They are commonly used in automotive, aircraft and electronics equipment as well as other commercial and industrial applications. Rivet Assortments are also available.
Blind rivets are commonly measured by both the body diameter and grip range. The grip range is the total thickness of materials being fastened with the rivet. The range should always be shorter than the rivet body.
It is important to determine shear and tensile strengths required for your application and then select the rivet to best meet that requirement. Shear strength is the force/load on the joints of the plate moving in opposite directions perpendicular to the rivet. Tensile strength is the force or load required to pull the plates apart parallel/along the length of the rivet. Style, material, diameter and fastener spacing all can be a factor in the ability of a rivet to hold the material properly.
Types of Blind Rivets:
Closed end sealing rivets have a cup-shaped end that seals tightly to prevent liquid and air from entering. They should be used where a watertight seal is required. They offer the benefit of great shear and tensile strengths as well as increased mandrel protection.
Color coded rivets are color coded based on material for easy identification.
Drive rivets have a small mandrel that is driven with a hammer.
Flush on both sides rivets have a head on both sides of the rivet. They are used in countersunk holes in low-clearance applications.
Lockbolt rivets have a locking groove design that provides strong, permanent connection in high-vibration applications.
Multi-grip rivets have a wide grip range to ensure the hole is filled. They are ideal for oversized, misaligned or oddly shaped holes.
Structural rivets with a locking stem have a locking collar on the stem that creates a watertight, vibration-resistant bond.
Screw mount rivets are reusable one-piece fasteners that have a pre-driven pin that quickly installs into a workpiece. They are vibration-resistant and ideal for low-to-medium applications.
Open end rivets are used when disassembly is difficult or not required. They produce a neat, low profile.
Peel rivets have four petals that bend outward and secure to the back of the workpiece.
Plus blind rivets are used in brittle or thin materials when only one side is accessible.
Push-mount rivets snap into holes using only a finger. They have legs that expand to secure materials and then release when the head is pulled.
Structural rivets are used in structural, limited-clearance applications. They have high strength properties and good resistance to corrosion and tampering.
Tri folding rivets have three legs that split behind the workpiece to secure the rivet in place.
More Rivets from MSC:
Panel rivets are push-in fasteners that resist shaking, vibration, loosening and abrasion. They are inserted into punched or predrilled holes in thin materials.
Solid rivets are strong, permanent fasteners used in structural applications such as bridgework and aircraft assembly. They are installed into punched or predrilled holes to fasten multiple workpieces together.
Semi-Tubular rivets have a partially hollow shank that buckles up and holds the workpiece. Split rivets have two legs that split apart and grip the workpiece after they are inserted into a hole. Semi-tubular and split rivets are used to permanently join lightweight or thin materials together, such as leather, wood, fiberboard and aluminum.
