Identification could include fasteners such as

CherryBUCK—strong, one-piece, structural fastener
turnlock fastener—secure inspection plates, doors, cowlings, and other removable panels on aircraft
Dzus—secure doors that open frequently
Hi-Lok—a turnlock fastener that, once the wrenching device is tightened to the appropriate torque value, shears off, leaving the locking collar
Hi-Lite—a smaller, lighter version of the Hi-Lok, offering great strength-to-weight ratio
Hi-Tigue—preloads the hole it fills, resulting in increased joint strength, exerting radial force
Jo-Bolt—used in close-tolerance holes
rivet nut—threaded rivet, used to create a threaded hole that accepts a machine screw for attaching a deicing boot
Taper-Lok—the strongest special fastener used in aircraft construction; cork-like
solid rivets
