Structural rivets, also known as Huck Rivets, Lock Rivets or Monobolt(r) provide exceptional shear and vibration resistance. They feature an internal lock that ensures mandrel retention to prevent pull-out. They have a wide grip range that allows one rivet to be used for multiple thicknesses, reducing the number of different fasteners to keep in stock.
Bulb-Tite
Gesipa Bulb-Tite structural rivets are ideal for use in applications requiring high tensile and shear installation values. They can be used to join aluminium, steel or Monel materials and are supplied with a neoprene sealing washer. Their large blind-side bearing head evenly distributes the rivet’s high clamp force allowing soft, thin or even brittle materials to be joined without damage. Unlike standard rivets, their mandrel breaks flush with the rivet head to resist pull through in high tension applications.
They can be installed using a standard rivet gun and are available in a wide range of diameters, with the option of a Shaveable series for repair work to solid riveted assemblies. These rivets have a protruding mandrel that is trimmed with the RV57 trimmer or a HS310 shaver installed in a standard 3/8" drill shaves the rivet head to match the appearance of a brazier head solid rivet. This feature also allows the use of a thinner rivet for elongated holes, reducing inventory and handling costs.
Tri-Fold
Tri-Fold rivets (also known as Oscar rivets) are similar to blind rivets but with the shaft splitting into three separate legs during installation. This allows the rivet to fold and flare out creating a large bearing surface which helps resist pull-out or cracking in plastics and other brittle or soft materials. These rivets also have locking mandrels to prevent loosened rivets and a wide grip range from 1mm to 12mm.
These rivets are ideal for lightweight material applications. They are commonly used in car body assembly and repair, RVs, kayaks, sporting goods, appliances and plastic components. The split tail on these rivets creates a propeller shape anchor on the blind side of the rivet during setting, allowing the clamping force to be spread over an increased area, making them a great alternative to solid or bucking type rivets in lightweight material applications.
These rivets are designed for use with the pneumatically or electromagnetically actuated squeezing tools but can be upset by hand using a ball-peen hammer. They provide superior shear and tensile strength compared to other types of rivets, making them an excellent choice for high-vibration applications.
Allok
Unlike common blind rivets that can fall out during the setting process, structural rivets have a built in locking mechanism so that the mandrel stays in place. This design also helps prevent galvanic corrosion between dissimilar metals.
These rivets expand under the closing head during the setting process creating an extremely powerful grip and also provide excellent vibration resistance. They are available with a wide variety of head styles including dome, large flange and countersunk.
When choosing a rivet you must determine the type of material and thickness the rivet will be used in, a good starting point is to consider its “material grip range”. The grip range is based on how much the rivet can be installed without being damaged.
Magna-Lok
Also known as Huck rivets or lock rivets, these super strong industrial clamping fasteners are perfect for high vibration resistance applications. They are commonly found in heavy fabrication such as truck trailers & security fencing.
An air or cordless battery powered huck gun will be your best bet for frequent use. Air huck guns are easy to use, economical, install quickly and consistently. Cordless huck guns have the added benefit of being portable, but aren’t as powerful as their air counterparts. They still require a steady hand and physical exertion.
