Overview
This Amazon Basics pack holds 18 rounded-corner hinges at 3.5 by 3.5 inches with a 5/8 inch radius, matte black finish, and 108 included screws, sized for the curved mortise cut into most factory interior doors.
Unlike the square-corner version in the same line, this is the profile that matches a standard pre-hung door straight out of the box, since most manufacturers round the hinge mortise to a 5/8 inch radius rather than squaring it off. Eighteen hinges is enough for a whole-house project rather than a single door.
- 18 hinges per pack
- 5/8 inch radius rounded corners
- 3.5 x 3.5 inch matte black steel
- 108 mounting screws included
Who it's for
Anyone replacing or adding hinges across several interior doors where the existing mortise has rounded corners, the standard factory cut. Skip it if your doors were mortised square.
Pros and cons
- 18 hinges, enough for a full-house project
- Rounded 5/8 radius matches most factory mortises
- 108 screws included
- Matte black steel
- Wrong profile for square-cut mortises
- Large pack size is wasted on a single-door job
Performance notes
Steel construction at 0.44 inch leaf thickness and 3.5 by 3.5 inch overall size matches standard interior door hardware. The 5/8 inch radius corner is the dimension that determines fit against a pre-cut mortise, so it's worth checking the existing hinge before ordering.

Frequently asked questions
What radius corner does this hinge have?
A 5/8 inch radius, the rounded profile used on most factory-mortised interior doors.
How many screws come with the 18-pack?
108 screws, six per hinge.
Will this fit a door mortised for square-corner hinges?
No, the rounded corners need a matching rounded mortise; a square-cut pocket needs the square-corner version instead.
