Which of the following is listed as a stock form of metal?

• A. Sheet
• B. Screw
• C. Wire
• D. Bolt

Answer: (A)

Stock forms are the standard shapes metal is supplied in for fabrication. Sheet metal is a flat, thin form that teachers and suppliers use as a basic starting material because it’s easy to cut, bend and form into many different parts. This makes sheet a fundamental stock form. Screws and bolts aren’t raw shapes of metal they’re finished fasteners used to join parts, so they’re not considered stock forms. Wire is also a metal form, but in this context the emphasis is on sheet as the primary stock material ready for forming into components.
