Design Information

The shear and tensile strength of the rivet selected and the number of rivets used in the application should equal or exceed the joint strength requirements. Typical ultimate shear and tensile strengths are listed by diameter and alloy in each rivet specification chart. Testing is always recommended before final selection and use in product.

The rivet body material should be compatible with the materials to be joined to resist galvanic corrosion which may result in reduction of joint strength. If dissimilar materials are widely separated on the galvanic chart, it is advisable to separate them with a dielectric material such as paint or other coating.

Marson can paint colors to match, as well as anodize or plate to your specifications.

After determination of strengths required by diameter and alloy, the total thickness of material to be joined must be considered. The grip range for each rivet is listed in each rivet specification chart. Select the rivet grip range which includes the total thickness of materials to be joined. Please note that the rivet barrel length (L) is not the grip range.

Recommended hole sizes for each rivet diameter listed on the specification chart should be followed closely. An undersize hole will not allow insertion of the rivet body; an oversize hole will reduce shear and tensile strengths, and may cause improper rivet setting, all of which promote joint failure.

The various head styles are offered to accommodate different assembly needs. The most popular Klik-Fast rivet is the buttonhead, whose lower-profile head is twice the diameter of the rivet body. This provides adequate bearing surface for nearly all applications. The large flange Klik-Fast rivet provides greater bearing surface for fastening soft or brittle facing materials. The countersunk Klik-Fast rivet is available for applications where a flush appearance is required. And the closed-end rivet is ideal for electric or electronics applications.

Besides the sizes, alloys and head styles listed, we manufacture a wide range of special rivets to accommodate a variety of customer needs for strength, head style and grip range.
