Concealed Joist Hanger 2x4 Steel Brackets, 12 Pack

Concealed joist hanger hardware secures 2x4 beams with a clean, hidden look for outdoor frames, swings, and pergolas. Designed for standard 1.93 x 3.62 in (49 x 92 mm) lumber, each concealed-flange joist bracket wraps the beam for added stability while the included M6x30 self-tapping screws speed up installation. Built from 2 mm steel with a black anti-rust coating to handle rain, heat, and long-term exterior use.

• Fits standard 2x4 lumber (internal 1.93 x 3.62 in / 49 x 92 mm) for a snug, supportive seat.


• Includes 12 concealed-flange hangers + 120 M6x30 self-tapping screws for a complete install kit.


• Delivers added rigidity with L-shaped reinforcement and four-sided coverage to reduce twisting.


• Installs fast with 10 pre-drilled holes—mount, slide in the joist, and tighten; no welding needed.


• Supports versatile builds like pergolas, swing sets, fences, wooden slides, decks, and cabins.

Keep your outdoor project aligned and visually neat with concealed mounting hardware that hides fasteners while reinforcing the connection point. The thick steel construction and corrosion-resistant coating are suited for exposed environments, helping maintain frame integrity through seasonal changes. Whether you’re upgrading a swing chair frame, building a pergola, or reinforcing a fence structure, this 12-pack gives you the quantity and matching screws to finish without last-minute hardware runs. Grab yours today and build with a cleaner finish and confident support.
