Which component is used for wood subfloor anchoring?

• A. Platform Gate
• B. Control Box
• C. Lag Screws
• D. Masonry Anchors

Answer: (D)

When anchoring to a wood subfloor, you need fasteners that bite into wood fibers and resist pullout and lateral movement. Lag screws are designed for wood applications because their coarse threads and relatively thick shank grip the wood securely, providing strong withdrawal and shear strength to hold equipment bases or brackets in place. Drilling a pilot hole first helps prevent splitting the wood and ensures the lag screw seats properly to create a solid anchor.

Masonry anchors, by contrast, are intended for concrete or masonry surfaces and rely on expansion or wedge mechanisms into hard material; they won’t perform as reliably in wood and can fail or loosen. Platform gates and control boxes aren’t anchoring devices themselves; they are components/services within the system, not means of attachment to the subfloor. So the best choice for wood subfloor anchoring is lag screws.
