Overview
Amazon Basics' square-corner hinge comes twelve to a box, sized 3.5 by 3.5 inches with a matte black finish and 90 degree corners, plus 72 screws for mounting up to six doors at three hinges each.
Square-cornered hinges need a squared-off mortise, unlike the rounded style most pre-hung doors ship with, so this pack suits new construction, custom carpentry, or anyone cutting their own hinge pockets rather than matching an existing rounded cutout. Steel construction and a matte black finish line up with current black-hardware trends.
- 12 hinges per pack
- 3.5 x 3.5 inch, square 90-degree corners
- Matte black steel
- 72 mounting screws included
Who it's for
Builders and DIYers hanging multiple interior doors who are cutting square mortises, or replacing hinges on doors that already have square-corner cutouts. Not a fit for doors with rounded 5/8 inch radius mortises, the more common factory-cut style.
Pros and cons
- 12 hinges and 72 screws in one box
- Square-corner profile for custom or new-construction mortises
- Matte black finish
- Enough for several doors from one purchase
- Square corners won't fit a rounded factory mortise
- Screws included fit only these hinges
Performance notes
Twelve steel hinges at 3.5 by 3.5 inches with a 0.6 inch leaf thickness give enough bearing surface for a standard interior door's weight. The 72 included screws match the hinge count for a full three-per-door install without buying hardware separately.
