QUESTIONA Clevis bolt is designed to be used in which type of loading?

  1. ATension loads only
  2. BShear loads only
  3. CCombined tension and shear loads
Show the answer and explanation

Correct answer: B. Shear loads only

  • A — incorrect The Clevis bolt is never used in tension. The eyebolt is the special-purpose bolt used where external tension loads are applied.
  • B — correct The Clevis bolt is used only where shear loads occur and never in tension. It is often inserted as a mechanical pin in a control system.
  • C — incorrect General-purpose hex head bolts serve tension or shear applications; the Clevis bolt is limited to shear loads.

BACKGROUND

Bolts designed for a particular application are classified as special-purpose bolts; Clevis bolts, eyebolts, Jo-bolts, and lockbolts belong to this group. The head of a Clevis bolt is round and is either slotted for a common screwdriver or recessed for a cross-point screwdriver. This bolt is used only where shear loads occur and never in tension, and it is often inserted as a mechanical pin in a control system. By contrast, the eyebolt is used where external tension loads are applied, such as attaching the fork of a turnbuckle, a Clevis, or a cable shackle.

STUDY TIP

Pair each special-purpose bolt with its load: Clevis bolt for shear, eyebolt for tension.

KEY POINTS

  • Clevis bolts are used only where shear loads occur, never in tension.
  • Clevis bolts have a round head that is slotted or recessed for a screwdriver.
  • Eyebolts, not Clevis bolts, take external tension loads.
