🔍 Key Concepts

• Carefully study the section marked C in the illustration and notice the 1/4 - 20 NC - 2 notation and the way the hole is drawn. • Think about which fasteners are used with tapped (threaded) holes in solid metal versus which are used in thin sheet metal or hollow walls. • Review the typical uses and shapes of a countersunk flat head screw, a round head machine screw, a fitted/body bolt, and a molly screw.

💭 Think About

• Does the drawing show a threaded hole in solid material or an anchor that expands behind thin material? How does that affect which fastener can actually engage these threads? • If you placed a thin sheet of metal over this device, what kind of head shape would you likely want on the outer surface, and which of the choices is designed to work with a standard 1/4-20 tapped hole? • Which of the listed fasteners specifically requires a nut or tapped hole to function, and which one is meant for hollow walls rather than solid blocks?.

✅ Before You Answer

• Confirm which portion of the drawing (A, B, or C) represents a tapped hole (look for the thread symbol and the 1/4-20 NC callout). • Ensure you know that a molly screw is usually used in hollow walls or thin panels, not in a solid, fully threaded block like the one shown. • Verify which fastener type among the choices is a standard machine fastener intended to screw directly into a 1/4-20 tapped hole while clamping a thin plate.
