Nail-in anchors are rated from 500-1,500 pounds for a tensile load in concrete.

• A. Nail-in anchors are rated for horizontal loads only.
• B. Nail-in anchors are rated from 100-300 pounds for a tensile load in concrete.
• C. Nail-in anchors are rated for tensile loads in concrete but not specified in range.
• D. Nail-in anchors are rated from 500-1,500 pounds for a tensile load in concrete.

Answer: (D)

Nail-in anchors are evaluated by their tensile (pull) capacity in concrete, not by horizontal loading alone. The published ratings reflect how much axial load the anchor can safely carry in tension, and for nail-in anchors that capacity typically falls in a 500 to 1,500 pound range. The exact value depends on the specific anchor size, embedment depth, concrete strength, and installation quality. That’s why stating a range of 500–1,500 pounds for a tensile load in concrete accurately describes their performance. Other statements don’t match how these anchors are rated: some imply only horizontal loads, some give a much smaller or unspecified range. Always use the manufacturer’s data for the exact anchor you’re using.
