Using this type of blind rivet requires a pre-drilled hole through the materials being fastened, into which the blind end of the rivet is inserted. The standard blind rivet design features a tubular form with a mandrel running through the center. Unlike normal rivets which require access to both sides of a joint, blind rivets only require access to one side to fasten materials together.
Blindīlind rivets, also referred to as POP rivets, are fasteners which enable materials to be joined together when the back side of the joint (i.e., the blind side) has limited access or is entirely inaccessible.
This allows the two riveted surfaces to rotate with respect to one another, and so produce a permanent, hinged joint on a stepladder, for instance. It limits the deformation to the tail of the rivet without expanding the shank. The hollow tail serves another purpose, though. These holes permit the rivets to be upset using about a quarter of the force required for deforming solid rivets of like dimensions. Tubular rivets, sometimes called semi-tubular rivets, are similar to solid rivets except with holes in the centers of their tails. Solid rivets are available in a host of sizes and materials, with SAE 1010 and screw-machine steel being common, and brass, nickel-silver, bronze, copper, stainless steel, and aluminum being popular, as well. The other three methods offer significant improvements in the quality of the finished head and its strength. Staking is often done manually with a rivet gun and mandrel, or bucking bar. Four methods are used to clinch the unheaded side, including staking, spin-roller forming, orbital forming, and radial forming, with staking being the fastest and cheapest method but one which leaves the formed head relatively unfinished. They are available as cold- and hot-headed varieties in flat, cone, button, and countersunk head styles. With their full-bodied design, solid rivets represent the strongest of the rivet varieties and, installed red-hot, were the rivets employed in structural-steel buildings and the like before bolted- and welded-joint techniques supplanted them.
