5 Tips for Using Blind Rivets Effectively
Fastening with blind rivets can be a cost-efficient method for fastening… some tips are
#1. The shear and tensile strength of the blind rivet selected and the number of blind rivets used in the application should equal or exceed the joint strength requirements.
#2. The blind rivet body material should be compatible with the materials to be joined to resist galvanic corrosion that may result in a 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 coatings.
#3. The total thickness of materials to be joined must be considered. Select the rivet “grip range” which includes the total thickness of materials to be joined.
#4. Use recommended hole sizes for each blind rivet. An undersized hole will not allow insertion of rivet body and an oversize hole may cause rivet failure, joint failure and could adversely affect rivet shear and tensile strengths.
#5. Various head styles are offered to accommodate different assembly needs. The most popular is the button head, whose lower-profile head is twice the diameter of the rivet body. This provides an adequate bearing surface for nearly all applications. The large flange rivet provides a greater bearing surface for fastening soft or brittle facing materials. The countersunk head rivet is available for applications where a flush appearance is required.
