Which of the following is not listed as an anchor type?

• A. Nylon
• B. Cross-plate
• C. Expansion
• D. Screw

Answer: (A)

Anchor types are defined by how they work to hold in the wall, not by the material they're made from. Cross-plate anchors spread behind the wall to grip, expansion anchors rely on the anchor body expanding or the sleeve pressing outward as you tighten the screw, and screw anchors create a secure hold by the screw biting into the substrate. Nylon refers to the material used in some anchors, but it isn’t a distinct mechanism or type of anchor. It describes what the anchor is made of rather than how it functions, so it isn’t listed as an anchor type. The other options fit the mechanism-based categories, which is why they are considered anchor types.
