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. Testing is recommended before final selection and use in product.
2. 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.
3. After determination of strength required by diameter and alloy, the total thickness of materials to be joined must be considered. Select the Rivet grip range which included the total thickness of the material to be joined.
4. Recommended hole sizes listed for each rivet diameter should be followed closely. An under size 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.
5. The various head styles are offered to accommodate different assembly needs. The most popular is the button head, whose lower profile head is approx. Twice the diameter of the rivet body. This provided adequate bearing surface for nearly all applications. The large flange head rivet provides greater bearing surface for fastening soft or brittle facing materials. The countersunk head rivet is for electric or electronic applications.
6. Besides the sizes, alloys and head styles listed, State Engineering Works manufactures a wide range of special rivets to accommodate a variety of customer needs for strength, head style and rip range.
