Insert the tool into a drill, position the guide onto the rivet head, and drill the head off and the rivet out.Typically used by aircraft mechanics, the tool consists of a drill bit and guide that positions the bit over the center of the rivet.If you have a lot of rivet removals in your future-let’s say you’re restoring an Airstream trailer or an old Cessna-you might consider buying a dedicated rivet removal tool. Option 1: Drill it Out With a Dedicated Tool There are a few methods to remove a rivet. For instance, when replacing sections of gutter or downspouts, you may need to remove rivets to disassemble the parts. Occasionally, you’ll need to reverse the procedure and remove the rivet. ![]() As involved as that sounds, the whole procedure takes less than a couple of seconds. The mandrel then breaks off at a predetermined weak spot, leaving the rivet flush with the surface of the material. As the mandrel is withdrawn, it causes the tube to swell, locking the two pieces together. The rivet is inserted into the hole and, using a rivet gun the mandrel is withdrawn through the tube. How to Install a Pop RivetĪfter the two sections to be riveted are aligned, a hole that’s the diameter of the rivet is drilled through the layers to be joined. Made of a soft metal, usually aluminum or copper, a pop rivet consists of a small nail, called a mandrel, inserted into a tube. Around the house, they are most typically used to join sections of gutters and downspout fittings. Pop rivets are used to join two pieces of thin material, such as plastic or aluminum, from one side, eliminating the need to access the back of the workpiece. (“Pop rivet” is actually a genericized term for the Stanley Engineered Fastening’s POP brand rivets.) ![]() These days, the rivet you will most likely encounter is a smaller, lighter-duty version called a blind or “pop” rivet. While one worker applied pressure to the head, another worker then peened over the tail protruding from the steel with a manual or pneumatic hammer. These rivets were thick iron plugs with mushroom-shaped heads that were heated until they were red-hot and placed into holes in the steel. Before the widespread use of the structural bolt, rivets were used to join steel plates that became bridges, skyscrapers, tanks, airplanes, and ships. ![]() Posted in Reference Data, What's New Tagged bit, Drill, Rivet, Shear, Sizes, StrengthIf you hear the word “rivet” and immediately think of an industrious woman named Rosie, your point of reference would be sometime in the last century. You can browse all of our spreadsheets hereįor more references on rivets in the Technical Library click here There is a spreadsheet available for this method here This compensates for the reduction in rivet shear strength resulting from high bearing stresses on the rivet at t/D ratios less than 0.33 for single-shear joints and 0.67 for double-shear joints. ![]() In calculating protruding-head rivet design shear strengths, the shear strength values obtained from Table 8.1.2(b) should be multiplied by the correction factors given in Table 8.1.2.1(b). For the double shear strength of a rivet, the values in the table below can be doubled. These strengths are the solid rivet shear strengths and describe the shear strength of the shank of the rivet. Rivet Shear Strengths are taken from (MIL-HNDBK-5H, 1998) Table 8.1.2(a) and Table 8.1.2(b). Rivet Shear Strengths for common rivet materials, drill bit sizes and modification for sheet thickness
