Title: Identify the functions of standard- and special-use fasteners used in aviation maintenance.
Course: Aviation Maintenance Technology II (20114-II) > Section: Exploring Aircraft Materials and Processes

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
- nuts
  - plain
  - Castle-nut
  - self-locking
- pins
  - roller
  - clevis
  - cotter
  - taper
- washers
  - plain
  - split-lock
  - high-strength
  - shake-proof lock.
