How Much Weight Can Drywall Anchors Hold In Your Home?
This blog post details a HomeLAB test conducted to determine the actual weight capacity of various drywall anchors, comparing their performance against manufacturer claims. The experiment was initiated due to skepticism regarding the stated weight limits of drywall anchors, which are essential for hanging items in areas without wall studs. The testing methodology involved installing each drywall anchor into a standard one-half inch drywall panel, strictly adhering to the manufacturer's installation instructions. A tension scale was then connected to the installed anchor, and this scale was subsequently attached to a hook screwed into a 2x4, which was securely fastened to wall studs. A turnbuckle was used to gradually increase the tension on the anchor, and the weight at which the anchor failed or buckled was recorded. This systematic approach ensured consistent and measurable results for each anchor type.
Seven different types of drywall anchors were put to the test: Everbilt Ribbed, Cobra TripleGrip, Pop Toggle, E-Z Ancor Twist-N-Lock Medium Duty, Toggler SNAPTOGGLE, Cobra DrillerToggle, and WallClaw Anchors. The Everbilt Ribbed, with a claimed capacity of 22 lbs, remarkably held 80 lbs, exceeding its rating significantly. The Cobra TripleGrip, rated for 45 lbs, performed similarly to the Everbilt Ribbed by holding 90 lbs. The Pop Toggle, with a 60 lbs claim, demonstrated exceptional strength, supporting 130 lbs—more than double its stated capacity. The E-Z Ancor Twist-N-Lock Medium Duty, marketed for 75 lbs, successfully held 100 lbs and was noted for its ease of installation without requiring pre-drilling.
The Toggler SNAPTOGGLE emerged as the best overall performer, rated for 80 lbs but capable of holding an impressive 180 lbs, reaching the maximum tension the testing apparatus could apply. The Cobra DrillerToggle, with a 90 lbs claim, held 140 lbs, featuring a unique design where a metal arm tightens against the drywall as a screw is driven in. In contrast, the WallClaw Anchors, also rated for 90 lbs, met their claimed capacity but failed by popping out of the drywall when exceeded, creating a large hole. The comprehensive testing revealed that nearly all anchors exceeded their advertised weight ratings, providing a practical guide for consumers on selecting appropriate drywall anchors based on actual performance.
