VERSATILE HOLD: Designed for hollow + solid installs—concrete, brick, stone, and drywall—this TOGGLER anchor grips securely under load, while the flanged head boosts stability in cavities for reliable concrete wall anchors performance. SMART EXPANSION: Corrosion-resistant polypropylene expands and elongates in solid substrates to spread force evenly, then opens “jaws” behind hollow surfaces as the screw drives in, making heavy duty wall anchors for drywall tougher and steadier. INCLUDES SCREWS: Made in the USA and supplied with #10 x 1-1/2" sheet metal screws, so you can fasten right away without extra parts, ideal for mounting brackets, fixtures, shelving, and household hardware. STRENGTH RATINGS: Tested ultimate tensile strength reaches 69 lb in 1/2" drywall and up to 675 lb in 3,500 psi concrete when used with the included #10 sheet metal screw, supporting demanding mounting applications. SAFE LOAD GUIDANCE: For safer real-world use and to meet local regulations, set working loads at one-fourth or less of the published maximum values, helping reduce risk while maintaining consistent, reliable performance.
