STANDARD BUTTON OR ROUND HEAD RIVET DIMENSIONS STANDARD 90 Degree (+/- 2) COUNTERSUNK HEAD RIVET DIMENSIONS Virtually no scrap is produced during the manufacturing process.Inexpensive alternative to threaded fasteners.Permanent fastener that cannot be removed without destroying one of the rivet heads.Material grain flow structure of solid rivets, along with the shank swelling during assembly, creates the strongest riveted joint.
Rivets feed automatically in impact Rivet Machines that cycle in approximately 3/10th of a second Pre-punched or drilled work-piece holes are required for use on most solid rivet applications. Spun/orbital/radial rivet clinches require less tonnage to form than impact or pressed rivets therefore, do not have the same shank swelling capability. A lower head height than standard domed head rivets provides a more finished appearance. They are lightweight, nonmagnetic, and chemically treated for good corrosion resistance, leaving a gold-colored finish. We sell the most common sizes in bulk packages of 100 or 1,000 pieces. Made of heat-treated aluminum, these rivets meet MIL-C-5541. Swelling of the shank occurs most by the clinched head end of the rivet. These solid aluminum rivets are made to expand in the hole and securely lock two. When impact or press clinched, the force required to form the clinched head of the rivet swells the entire shank of the rivet to completely fill the work-piece hole. A solid head is formed (upset) to create the clinched head of the rivet. To fasten the rivet, the end of the shank is impacted, pressed or spun after the rivet has been inserted into a work-piece. VFG manufactures solid rivets with a variety of head styles in addition to flat heads. Many solid rivets are ordered with a plain finish as they are painted after assembly. Rivet plating and coating options are selected dependent on the application.
Rivets can be hardened for some applications to improve strength and durability. Secondary heat treatment (anneal) to the rivet can make the rivet more ductile prior to clinching in certain applications. Common head styles are oval, truss, round, button, universal, pan, countersunk and flat.Īluminum solid rivets are the strongest rivets used in fastened joints. A die point can be manufactured into the shank end to aid alignment during assembly. The shank of the rivet can be produced with a straight cut-off or a chamfered cut-off end. A solid rivet has a manufactured head on one end and a solid shank on the other end. Valley Fastener Group manufactures a variety of solid rivets, including stainless steel, copper, aluminum, brass and steel flat head rivets.
